Brilliant, and fascinating! Many thanks for recording as you went on tour. I don't have the budget for UK manufactured speakers (800 series) but note the trickle down effect to 700... Particularly interesting to hear some of the details that make the sound so great.
AVS paid off to botch the detail shots! Lol j/k, love you AVS, thanks for the tour! I absolutely love how overengineered their speakers are, I had no idea that they were so solid. I am honestly not sure how they are able to sell them at their current price point. That guy knew his stuff, you can tell he has an engineer brain by how passionate he looks about every detail without smiling one time. xo
Quality engineering and manufacturing is never cheap folks. I compared the 803D 3's with others in their price range and they won out every time with their uncolored, neutral sound. They sound great with all genres!
I mean, factually, objectively, they are quite heavily coloured/not neutral - the entire 800 series have a significant peak in frequency response around the 10k area, which is what causes them to sound sibilant in so many systems. But I do agree they are some of the best performing speakers on the market, outside of that (likely intentional) issue.
@@LordVictorHalgaard have you heard all of them? I have and the 800 d3 and the 802 d3 do not exhibit that behavior but the rest of the line does without question and yes the amps are VERY important - McIntosh is the most synergistic
when I first got mine I put a couple pairs of sweat socks over the tweeter. Then a passive equalizer , which worked great to tame the “ headphone sound “ .
I'm a retired woodworker, home builder, cabinetmaker, Mold and Model maker. I have to say, this manufacturing process and attention to detail is inspired and inspiring. As a retired Social Worker/Case Manager i will never afford the 800 Series Diamond speaker pair. But i am nearly in the market for a new pair of front speakers. Currently, my 5.1 system is connected to 4, DM303's and an HTM62 center. I've updated my interconnects and speaker cabling with Furutech in nearly every instance and i have found the 303's just sound better and better. The sound is so clear, detailed and with an amazing sound stage. In fact, i cannot identify the speaker placement they seemingly disappear into the sound-stage. Anyone who listens to this humble system looses control of their jaw as their jaw drops to the floor. With todays lossless audio formats, well recorded music gives me the cymbal crashes and the sharp crack of the snare drum and the chirping chord change from the strings of the acoustic guitar and so much more... Recently, I've been looking to up my system to a 7.1 array (probably more than i need). However, lately i've been hearing and reading great reports regarding the Continuum driver in the new 600 and 700 series speakers. I've been thinking i might try the B&W 607's..., does anybody have thoughts or experience with listening to any of the new continuum driver configurations. Whatever i land on will probably remain in my system for eternity (obviously). With the asking price on B&W speakers in general i'd be bummed if in a few years i feel i'm missing something in sound reproduction. I know any system can be improved upon. With upgrades, tweaks and positioning at times it's hard not to tweak the system for every new song. Any thoughts will be helpful. (sorry about the length of my comment) Well done B&W and thanks.
@MAD GRUMPYMAN Thanks for your comments. i totally agree with your thought/experience with quality front speaker pairs. Two speaker systems can act as a more than adequate sound reproduction tool. i've lived with a few decent even nice speaker pairs in the past. The Mission 765's and Celestion SL12si's to name a few. i felt these were exceptional speakers. i was happy even satisfied with the above speaker pairs especially, but of course not every recording is created equally and one frustration seemingly leads to another and all too frequently i would find myself at the controls attempting to dial in the magic..., sometimes it worked. To make a much longer story, very brief - a friend (Roger) i've known for a very long time has an unavoidable impulse to own every vintage and popular speaker to ever cross his path and he has room after room of speakers in storage as evidence. Unfortunately for me, he believes every speaker he owns is worth its weight in gold..., maybe true but he offers no financing (lol). In any case, Roger had a sub/sat speaker system set up on one day i happened to drop by. That day i left with a slightly muddy sounding PhaseTech passive subwoofer. A 14" cube with a 10" down-firing Morel driver, i think. The idea of a subwoofer playing the longer sound waves below 80hz freeing the 5-7" drivers to focus their energies on the upper range musical details sounded logical. Since the 80hz sound wave, even half a sound wave below 80hz fills any conventional room with sound, it's then, an easy task to believe the LF sound is coming from any point within the sound stage. To be brief, I'll end with, in my more productive years, my son lived with me and as a single dad, there are priorities. So, the newest car i've owned was a 3yr old Subaru and i am not complaining, i loved that car. As long as i've owned a Subaru i've never been snowbound and i have seen some incredible scenery in my home state of Maine. If car dealers ever offer a 0% financing for 6 or 8 years i may yet qualify to purchase a new car. As for a 6-9 thousand dollar pair of speakers - i've been looking, ever since i noticed Music stores have been offering 0% financing for 48 months on instruments. That may up my investment in a better quality speaker pair like the B&W 707's. But i'm not holding my breath. Besides, i have read several great reviews, very flowery and flattering reviews about the B&W 607's and add that to the idea Roger has always preferred a 5.25 driver he says it makes for a better sounding Sub/Sat speaker array. I don't disagree, for vocals he is absolutely correct (i think) but i find with some 6-7" drivers there are added layers of detail and with new technologies and reviews raving about the B&W 607's... Bottom line it'll take the federal government awarding the American People the full $2000 CoVid-19 relief amount - if that does happen i may be able to make an offer on an even better quality, epic, used pair of B&W speakers. Again, i am not holding my breath. Hope your able to stay safe thru these Holydays with family. Best Wishes for your New Year. my apologies for the longer reply
That's the reason the are so good ...because they are not the new design ...Most 60s 70s 80s stuff was brilliant.....man made better quality. the new series just has to much emphasis on computer based technology
Wow, amazing video and shows how much work goes into making these fantastic speakers and that NOT ALL speakers are made the same! Thanks for the video!
They're worth the money just for that level of attention to detail and quality of components! I've never listened to anything in this price range, but I'm guessing once purchased, they'll produce quality sound for a couple of generations at least 😂
No they're not and I've listened to a few. Get a Genelec 8531 and be happy. It's more reasonable priced, has matching amplifiers built in and is filled to the brim with quality engineering and manufacturing. If you need more low-end, get multiple subs and set them up properly with the guides you can find online.
@@iliketoast-q9b yeah, figured as much! I'm using diy line arrays with quad 12" subs. Now the room has the most scope for improvement. Figuring out the cheapest way to make effective acoustic panels is almost as much fun as building speakers 😉
12:04 They use a diamond dome to be able to present the finest details in music and then 16:21 they use ferro fluid to wipe out some of the details again... Okay, to be fair, the material of the voice coil former also plays an important role in that.If it's made from aluminium it's also decreasing detail.
@@DanielFSmith : I'm sorry but your example doesn't fit here. In a car you want a smooth ride. The electrical equivalent would be DC. In a speaker movement is the main purpose. To use your analogy: I want to experience not only every bump in the road and each small stone I go over, I want to feel every tiny bug I accidentally crush under my tyres. I want the finest changes of the signal to be presented to me. That's why I dont want a _controlled_ movement.
@@mariusloubeeka5810 When you ask your mechanic for more "road feel", would they install performance shocks or weaker ones? Sure, the damper removes sound energy. That's what you need! Look at/measure the resonance curves for undamped speakers as you bounce down the road. (Would be a good topic for your podcast, in fact ;-)
@@DanielFSmith : As I said, the car example doesn't really fit. My speakers (link to one of my videos about them below) do have quite strong cone break-up resonances because they have stiff diaphragms (beryllium dome & fibre-reinforced paper). That is also the reason why all resonances are shifted to higher frequencies (woofer: >5 kHz, tweeter: ~30 kHz) where they are either filtered out by the crossover (@ 2 kHz, 3rd order) or in a non-relevant range (>22 kHz). I dare to say that they can compete from let's say 300 Hz to at least 40 kHz with any B&W diamond speaker. With a good soobwofer even below 300 Hz. Thanks for mentioning my podcasts! I think I already said something about that topic in one of them. My _Illuminata 15_ speakers: ruclips.net/video/gMyE3SUvSeM/видео.html
@@mariusloubeeka5810 I'm sure you appreciate that a non-relevant range is only non-relevant if everything in your system (cone, enclosure, room) is perfectly linear! If you get enough energy accumulating at 22kHz anything can start to resonate. You're only really safe when the air becomes your attenuator (at the relevant distance to the object).
Mygoodness. The depth of engineering is Phenomenonal! Unfortunately, I'd never be able to afford these ever and will have to go with my Japanese/US combo.......
i knew the 800 series was good after B&W sent me a DVD with all the info like 10 years back.... but my god i didnt realise the engineering that went into them... these things are sooo sweet!.. but seriously overkill for anyone who isnt an audiofool!
I've heard that the diamond tweeters has a high weight disadvantage and that's why more high end speaker manufacturers don't use it in their monitors. And that Beryllium is a bit harsh. Would the Kii Three's gain anything by using super premium drivers? They seem to be the ultimate rated monitors/most accurate yet they use $70 third party tweeters in their $30k speakers.
So basically he's saying my brand new 600 plebeian series speakers have crappy magnets, sheet metal tweeters and a cabinet built like an Ikea flat pack.
I dream off the 800 series pretty much every night maybe when I get older and am earning more I might be able to afford some I’m using the CMS2 range at the moment not bad
but why copper coil on the tweeter, Why not aluminum, which has a much better weight to conductivity ratio??? it does not make sense. Is it because the copper coil will be small enough for the power rating?
So, the 800 series tweeter's voice coil is surrounded by a ferro-fluid material to dissipate heat into the aluminium structure/heat-sink; that's going to introduce damping. It would be interesting to see the FEA models of the tweeters (I assume they do FEA on the tweeters as well as on the cone designs) since a traditional second order ODE of the form x'' + (c/m)x' + (k/m)x = some function (m=mass, c=damping coefficient and k stiffness) would be too simple. There's an idea for a future RUclips vid: the underlying modelling work carried out for the tweeter in the 800 series.
The ferrofluid will evaporate - leaving behind nano-magnet-dust (that's when they start sounding funny and burn out). KEF tried ferrrofluid designs lang ago. Owners will need to get a refill from time to time
Ok so They press it to make the shape. I was always thinking they carve baffles from wood. This way can whatever shape they desire, using designed pressing tool
@MAD GRUMPYMAN Yes. For the price you pay for these speaks I am shocked that this has happened. And no I didn't have kids for 10 years when these got pushed in so kids are not the culprit. They collapsed on their own from used from some strange reason. The center channel is the only one not caved in and I this that is because it is the least used.
@MAD GRUMPYMAN I lived in So Cal and the speakers where there for 10 years until I got married. For whatever reason the tweeter covers got removed from several of the speakers when I moved and were lost. I just ordered new ones. They have been missing for about 15 years and I finally got tired of not having them. I found a B&W website that sells parts and ordered the tweeter cones also. I love these speakers but my wife hates them. If I die look for them on Craig's list because they will be sold before I am cold. LOL Thank You and enjoy. Also the reason I said it wasn't kids was that I posted before and people always says it is kids who poke them in. My kids after I got married used a crayon or something on one of the speaker screens but that is the worst thing they have done to them.
the problem with his logic about tweeters is: you're limited to the frequency response of the amplifier (i recognize a class a/b is gonna be able to play higher than class d, but upper limits is probably 40k), and the upper limit of frequencies that instruments can play is like 16k, so even though a record is capable of playing 50khz, the amplifier might only be able to play 20, and the music itself will only have up to 16. 20 is basically overkill, 70 is just to show off
Its always good practise to operate a driver well away from its break up point. Music harmonics - especially a pipe organ, can go as high as 50 kHz. Ok that is besides the point. Assuming your parameters then its nice if your driver breakup is 2 or 3 octaves away from the highest sound its expected to do. So 16 kHz for your music - one octave higher is 32k, two octaves is 64k.. so this tweeter is really only offering 2 octaves of safety. When a tweeter hits break up, the peak resonance is pretty nasty. Better to keep it a long way away.
@@theprof291166 Feeding a tweeter frequencies above 20 kHz (which is already very generous) is pointless and needlessly heats up the voice coil which introduces distortions and can lead to driver-failure at high volume-levels. Unless the resonance is within or right above the tweeters intended frequency-bandwith it will be completely inaudible anyway, so this supposed 2-3 octave safety factor is complete overkill.
likewise here. I like the look and dont mind the overengineering, but i dont love sounded speakers, like B&W definitely are. Perfect speakers in my opinion are very neutral, like studio monitors or a decent pair of Nubert`s
@@chewieone1064 Actually, B&W are extremely neutral. That's their calling card. And that's why some people don't like them because they're too stark. They don't sweeten the sound like, say, a JBL, which some prefer. To each his own.
You know , Magnet is not a Premium component , its actually low grade stuff . Because Magnet loses its magnetism on impact and distortion . And what is a speaker its a vibrating component . The Best speaker uses Electro Magnets , now you supply the power not the magnet so the distortion in the magnet is no more and is transfered to your power supply , and you dont care about that . . While you are at it you put in few extra things , like Servo control . This is something i would expect in a 30K speaker , and will do more for you then that Diamond tweeter playing at 50khz. And it wouldnt cost that much , nothing . And there are more things but not to overdo it here .
There is no appreciable loss of magnetic field strength at normal operation after years of use. Even at really high-power levels at which the voice coil fails you are usually not reaching temepratures high enough around the magnet to cause demagnetization. Hence why busted drivers are regularly reconed and re-used in pa-systems which get fed kilowatts of power rather than a few watts and at most a few hundred watts in home-use situations.
@@iliketoast-q9b you didnt understand . there is magnetic loss as soon as you kick the magnet , try it at home , actually you dont have to do that you have online people that have done it , when magnet is kicked it losses its magnetism , let alone after years of use it becomes softer less clear sound , you really dont know electronics i see that , and they count on that . As Soon as Voice coil pushes the magnet it looses a percentage of its strength , and that = distortion . You know what also introduces distortion , filtering , those Analog 100 year old crossovers being able to filter at 12dB per octave , that is ridiculous , hence below 12dB your tweeter and bass play the same tune , and Tweeter being smaller reacts faster , and then you have phase issues , that is why its PARAMOUNT to have cut off frequency exceeding 24dB per Octave , you know what octave is , doubling in frequency , that way this filtering and phase issues happen below 24dB , and scientifically humans can not hear the sound that is 30dB lower then main sound , so actually the best crossover is 48dB per octave of filtering , but it is also 18dB overkill , so they mostly use 24dB and this is in the ball park of 30dB. Even in the days of Valve Amplifiers , people have made active crossovers with Valves , and each driver in the speaker would have its own amplifier , not to affect the other speakers . because when driver works , its Impedance changes and this is reflected up on Amplifier , so your bass driver kicks , impedance goes down or up , and then your tweeter if its on the same amplifier gets more power or less resulting in distortion . That is why it is also paramount for each driver to have its own amplifier , and even better to have each speaker with its own power supply , and even better have those speakers connected to Power Conditioner , making sure that it always gives 110/220V because , as your speaker works voltage varies depending on the amount of current pulled , or the Load , its Ohms LAW , so to get around that , you get Active power supply for your speakers , that all have their own amps for each driver , and active crossover with at least 24dB per octave , ideally at 2khz give or take . And that formula , being the best is employed in Studio Speakers where Clarity is of great importance . For mixers to hear their mixes properly , and so on . Only after all of this has been satisfied you can enjoy your Beryllium Tweeter , putting it on a passive speaker will not even work as titanium one that has its own amplifier . As you may have noticed i am Electrical engineer so i chose that 19 years ago , its Behringer Turth B2031A , they worked for 19 years and are still working , they have even been outdoors on rain at partys blasted at 100% , but they have the limiter built in so no mater what i do , i cant blow them . Actually i was planing to make a video about them , for im sure there are not many 19 year old Active speakers out there that have never been turned off , they are always on . You know why ? Because Amplifier circuit is a passive thing , has no moving parts , only thing that damages it is change in temperature . Leave them ON , tempreture is constant and there is no damage . That is why they work still after 19 years , but they do give a bit softer sound due to magnets being softer now , and rubber being softer , and all that . Capacitors being dry , things like that , but i dont want to change them , i want them in condition they are , untouched .
@@dedskin1 First off, congrats on your old B2031A still going strong, they're an awesome speaker for a very affordable price, I've recommended them often, but prefer to build my own speakers. If it ever dies on you, try the JBL LSR308 or Presonus Eris E8 XT. I'm a material scientist, former ee-student. Sorry, but what you wrote there is just plain wrong in so many places. You don't seem to have a proper grasp of system-theory or magnetism for that matter. Also learn the difference between the qualitative and quantitative. The induced magnetic field from the voicecoil interacts with the magnetic field of the ferrite magnet and that potential energy is then transformed into kinetic energy by moving the voice coil, NOT the magnet-structure. Permanent magnets have been used for decades with great results and there is no appreciable loss of force over time as long as you handle your speakers properly. Heck even in live-sound you don't see the effects you're describing, even though pa-speakers need to be hauled around a lot, taking a few hits here and there. I've build my fair share of both hifi- and pa-speakers and almost none of what you claim has been my experience. Now I'm a fan of active speaker designs myself, though I highly prefer DSP-solutions to opamps. But what you said about crossovers is just wrong. Both a high-pass and low-pass introduce positive group-delay since the slope of the phase changes. So while you may not hear that in the tweeter's signal down low, you will hear it from the midrange since it has a low-pass matched to the tweeter. So no, a 48db/oct-filter is not necesarrily the best option, especially when crossing over around the most common 2 kHz-range where our ears are most sensitive for gd-distortion. Also dome-tweeters are hardly the end all be all, not even with a diamond or beryllium dome since they only push the dome-breakup-mode up higher, but they beam about just as much as a silk-dome and don't go low enough to stay out of that sensitive midrange-bandwidth above 700 Hz or so. And yes I have seen more measurements than I care to remember where this was obvious.
@@iliketoast-q9b let me tell you something , there are many speakers that are good all that are made with active crossovers and amp for every driver , boxed well leveled well , there are many , like Mackie 8s , Behringer 2031a being a copy of it , but Mackie has SMPS power supply , while Behringer has Toroidal transformer , and do you know that Transformers are better , because they react faster to changes in load current demand .Yet Mackies are more expensive , because people dont know what they are buying , 90% of time . Everything ive said is based on my experience , a long experience since i have B2031A for 19 years , and that is only 5 years after i finished Engineering school . The magnets lose their strength no doubt about it , mine lost 30% over that 19 years . And it doesn't matter if you use kinetic energy or electro magnetic energy . Makes no difference , It is Electromagnetic force either way , becase on Atomic level , there is no touching , nothing touches the Magnet even if you kick it with a hammer , they dont touch . So Voice coil being an electromagnetic magnet does so to say Dance with the Magnet , its not all perfect . This is measurable ,you have parasitic currents , parasitic magnetic currents , this is all reaction of electromagnet with a magnet . That is made by heating it then applying Electric field . You remember in Shop when you buy something and the clerk on the table demagnetizes the holder ? Everything i have said is known , its nothing new , there are Servo Drivers to fix the issue of magnet and coil dance . And JBL 308 do not have a separate amp for the tweeter far as i know , i wont google it but i think they dont . I am not fermiliar with 8XT I am familiar with coaxial design of Fluid audio 8 inch , it really does sound like you have head phones on . this may be good for some , bad for others , but it does present Stereo Image better then B2031A due to box design , rest is i think the same . one being Coaxial the other 2 way vertical . If you think im wrong and magnets do not lose their strength then i wont stop you , i know they do . And i also know Voice coil and stationary magnet do play a dance , once you can write books about , there is much to say , but is irrelevant at this point . The most important thing in Sound System is not the System it self, but its positioning , the Room they are in . That is why B2031A is a near field monitor , made to be listened closly in small rooms , there are models made for bigger rooms . And there are models made for Hifi experience . But you must know that Human eyesight is garbage , we cant even see colors correctly without having something to compare it to , our Ears are even worse . So one should never base his opinions on what he hears , he must know what to listen for and that comes with knowledge , when you know ever corner on the speaker box is a tweeter on its own due to sound diffraction , then you know Egg shaped boxes are the same , but also expensive . And i fully support DIY projects , but they are almost always more expensive then just buying what you want .
@@dedskin1 So what, 30% lost over 19 years is totally fine. You just lose a bit efficiency and maybe your frequency-response changes noticably. But you're an EE, so you can fix that easily, especially since it's active. I don't have the time or patience to read that much poorly formated text though so please fix that. The JBL LSR308 does have a seperate amp-channel for each driver, but on the same die. EEV-blog did a tear down a few years back and experts who know more about audio than you or I combined have also said those LSR308 are about as good as it gets for the price. The E8 XT and a few others are also very good and similar in design of course. System-design is the most important actually, even more important than driver selection. Of course it should be done with the target, i.e. the room, in mind. I just built a double-18 sub for a pa-system a few months ago btw. Cost: just under 1000€, Celestion-drivers with ferrite magnets, plywood-cabinet. Performance: Worth about 4-8 times that, comparable to a KS28. Now of course if I were to pay myself an hourly wage it would be much more epxensive, but it's not like I would work and earn money if I wasn't building speakers in my spare time. I would be doing something else for fun and not for profit. Oh and my Crown XLi 1502 has a SMPS and can deliver plenty of power to my sub and fullrange-speakers just fine. Go ahed and have a look at audiosciencereview.com and see the measurements for yourself.
David Brent has a new audience... Having owned what must have been over five pairs of the 800 series loudspeakers I am very glad to have moved on to altogether 'proper' loudspeakers afterall. Its funny how carried away these manufacturers get, it's hardly aerospace engineering...
Zingali twenty evo 1.2 - I see zingali have just found a distributor in the US so these should be available for you to go hear for yourself to in Canada... I use the Gryphon Diablo 300 with them... I have heard there are better results to be had with diablo 120 due to the loudspeaker high sensitivity @ 6 ohm...
B&W speakers definitely come with grills. I think it must be that they find it easier to show them when they are off. A lot of people also choose to leave them off. It just depends if you have pets and kids. Though cats just love speaker grilles !
I could be wrong but I doubt most of the employees I saw on this video (apart from Andy Kerr) would have the finances or motivation to assemble a system which included an 800 series speaker. You never know though..
I didn’t get the comparaison with an exotic car better performing at 100kph than a cheap one: Il the speaker is rated +/-3db between 20hz and 20Khz, this means that it performs at its best within this range... why would we need to go much higher if that doesn’t improve the audible performances?
It DOES improve the audible performance, that's the entire point. A point of failure is never 'immediate', its gradual, so the closer you get to it, the more small issues will start appearing, which is why you want to move the point of failure as far away as possible. Put it this way: if I asked you to run 24+ km/h, you probably cant do that for very long, because its close to the average human limit, your failure point, you get winded, red in the face, sweaty - not very "composed". Most have to go to almost half that speed, to be able to keep it up for a long time: 13 km/h is a fairly normal marathon speed. So your "comfortable" or well composed speed is only half of your max speed - same with the speaker, in theory, to reach 20khz comfortably, you often need a much higher maximum limit.
For the 800 I've not money, but last month I had bought the 702 S2 My TT Rega 3 with Exact and my ampli-McIntosh are very happy. P.S Sorry for my English language, but i am Italien. Fabioo '961 12/12/2020 h. 01,17
Three comments: First, I own 804D3s. 1. Disappointed the tweeter tube is only there for show (as well as holding the tweeter). The original "Nautilus" premise was to let the tapering tube dissipate the back wave so it couldn't reemerge full-strength from the front (again). The demonstration clearly shows total tube blockage directly in back of the diaphragm. 2. The presenter mentions "safety concerns" regarding the speaker tipping over (from being top-heavy). I provided platforms for my 804D3s as it was clear they could fall over with minimal assistance ($325 out of my pocket). B&W thoughtfully provided platforms for their lesser model tower speakers. 3. Funny how the factory affixed some kind of paperwork directly to a driver cone with paper tape. More concern for the finish than the part people actually buy the speaker for? P.S. Wondering if the factory ever tried the plywood pressing procedure in a vacuum chamber? Could probably get a few more percent of stiffness with the glue getting sucked into every last crevice? Love my 804s BTW.
Kenton Kirkpatrick the tweeter tube is aluminium, almost sold aluminium, is thee primarily for heat dispersion, he says that, and heat dispersion is critical! In driver components. The front baffle on my speakers have a 9mm think aluminium plate that all drivers are mounted too, for this very same reason👍🏻👍🏻.
Kenton Kirkpatrick but yes, they should have shown us at least, the paper taped to the driver, I cringed😂😂😂. Nobody would ever get close to my drivers, and I certainly do not handle them myself, that was painful to see😂😂
I forgot to mention the "ferro fluid" which is used to cool the tweeter voice coil. Anyone know the shelf-life of ferro fluid? My understanding is ferro fluid dries-up over time. Can the ferro fluid be replaced or must the tweeter be replaced? Inquiring minds want to know...
Kenton Kirkpatrick well, I’d suspect it’s a life long substance, as he mentions that the cooling properties of it, means the tweeter never gets too hot and deteriorated over time, he goes on to say that because of this this sound always stays the same, throughout the speakers life. So I’d suggest it would be a life long substance based on this...👍🏻👍🏻
@@kentonkirkpatrick5225 Life long ferro fluid. Wow! Meaning you never change the oil in your car?! If it dries up you have two options #1 New Ferrofluid or #2 New Tweeter.
Why companies like B&W and others today's days selling basically I can not say lowend but midrange speakers as High end speakers for lots of money like 15 or $20000
14:20 Guess he doesn't know much about cars 😕🤦🏻♂️ What he should be saying is Koenigsegg. Not Bugatti (who's copied loads of Koenigsegg designs) and not McLaren.

@@LordVictorHalgaard have you heard all of them? I have and the 800 d3 and the 802 d3 do not exhibit that behavior but the rest of the line does without question and yes the amps are VERY important - McIntosh is the most synergistic
when I first got mine I put a couple pairs of sweat socks over the tweeter.
Then a passive equalizer , which worked great to tame the “ headphone sound “ .
The little speakers green, blue and orange are very sexy! I want a pair! Very good video! B&W ought to be proud of their products.
@mario j I wonder why you would like two different colors for a pair. Could you explain?
I'm a retired woodworker, home builder, cabinetmaker, Mold and Model maker. I have to say, this manufacturing process and attention to detail is inspired and inspiring. As a retired Social Worker/Case Manager i will never afford the 800 Series Diamond speaker pair. But i am nearly in the market for a new pair of front speakers.
Currently, my 5.1 system is connected to 4, DM303's and an HTM62 center. I've updated my interconnects and speaker cabling with Furutech in nearly every instance and i have found the 303's just sound better and better. The sound is so clear, detailed and with an amazing sound stage. In fact, i cannot identify the speaker placement they seemingly disappear into the sound-stage. Anyone who listens to this humble system looses control of their jaw as their jaw drops to the floor. With todays lossless audio formats, well recorded music gives me the cymbal crashes and the sharp crack of the snare drum and the chirping chord change from the strings of the acoustic guitar and so much more...
Recently, I've been looking to up my system to a 7.1 array (probably more than i need). However, lately i've been hearing and reading great reports regarding the Continuum driver in the new 600 and 700 series speakers. I've been thinking i might try the B&W 607's..., does anybody have thoughts or experience with listening to any of the new continuum driver configurations.
Whatever i land on will probably remain in my system for eternity (obviously). With the asking price on B&W speakers in general i'd be bummed if in a few years i feel i'm missing something in sound reproduction. I know any system can be improved upon. With upgrades, tweaks and positioning at times it's hard not to tweak the system for every new song.
Any thoughts will be helpful. (sorry about the length of my comment)
Well done B&W and thanks.
@MAD GRUMPYMAN Thanks for your comments. i totally agree with your thought/experience with quality front speaker pairs. Two speaker systems can act as a more than adequate sound reproduction tool. i've lived with a few decent even nice speaker pairs in the past. The Mission 765's and Celestion SL12si's to name a few. i felt these were exceptional speakers.
i was happy even satisfied with the above speaker pairs especially, but of course not every recording is created equally and one frustration seemingly leads to another and all too frequently i would find myself at the controls attempting to dial in the magic..., sometimes it worked.
To make a much longer story, very brief - a friend (Roger) i've known for a very long time has an unavoidable impulse to own every vintage and popular speaker to ever cross his path and he has room after room of speakers in storage as evidence. Unfortunately for me, he believes every speaker he owns is worth its weight in gold..., maybe true but he offers no financing (lol).
In any case, Roger had a sub/sat speaker system set up on one day i happened to drop by. That day i left with a slightly muddy sounding PhaseTech passive subwoofer. A 14" cube with a 10" down-firing Morel driver, i think. The idea of a subwoofer playing the longer sound waves below 80hz freeing the 5-7" drivers to focus their energies on the upper range musical details sounded logical. Since the 80hz sound wave, even half a sound wave below 80hz fills any conventional room with sound, it's then, an easy task to believe the LF sound is coming from any point within the sound stage.
To be brief, I'll end with, in my more productive years, my son lived with me and as a single dad, there are priorities. So, the newest car i've owned was a 3yr old Subaru and i am not complaining, i loved that car. As long as i've owned a Subaru i've never been snowbound and i have seen some incredible scenery in my home state of Maine. If car dealers ever offer a 0% financing for 6 or 8 years i may yet qualify to purchase a new car. As for a 6-9 thousand dollar pair of speakers - i've been looking, ever since i noticed Music stores have been offering 0% financing for 48 months on instruments. That may up my investment in a better quality speaker pair like the B&W 707's. But i'm not holding my breath. Besides, i have read several great reviews, very flowery and flattering reviews about the B&W 607's and add that to the idea Roger has always preferred a 5.25 driver he says it makes for a better sounding Sub/Sat speaker array. I don't disagree, for vocals he is absolutely correct (i think) but i find with some 6-7" drivers there are added layers of detail and with new technologies and reviews raving about the B&W 607's...
Bottom line it'll take the federal government awarding the American People the full $2000 CoVid-19 relief amount - if that does happen i may be able to make an offer on an even better quality, epic, used pair of B&W speakers. Again, i am not holding my breath.
Hope your able to stay safe thru these Holydays with family. Best Wishes for your New Year.
my apologies for the longer reply
Lovely, just bought the 805D3 yesterday! :-) it's lovely
@MAD GRUMPYMAN Correct 😀 I am powering them with a Hegel H390, streaming from Tidal Hifi over bubble upnp, soon with a Node2i instead.
Brilliant speakers those D3. I have the 805S and I think they are great.
Sayin lovely is f***ing lovely!!!
I have had pair of B&W speakers for 40 years now and they still sound fantastic.
True, like all (very) good speakers. Lol!
That's the reason the are so good ...because they are not the new design ...Most 60s 70s 80s stuff was brilliant.....man made better quality. the new series just has to much emphasis on computer based technology
Have 3 pairs of the 805s as I love them so much.
Looks amazing well done guys! Regards South Africa...
Great tour, thank you
Wow, amazing video and shows how much work goes into making these fantastic speakers and that NOT ALL speakers are made the same! Thanks for the video!
Me 26 minutes ago: What?? 26 minutes?! Ill just skip the though it real quick.
Me now: What?? Its already over??
Thanks for the excellent tour :)
Excellent video
スピーカーBOXの色がとても素敵です。
They're worth the money just for that level of attention to detail and quality of components!
I've never listened to anything in this price range, but I'm guessing once purchased, they'll produce quality sound for a couple of generations at least 😂
No they're not and I've listened to a few. Get a Genelec 8531 and be happy. It's more reasonable priced, has matching amplifiers built in and is filled to the brim with quality engineering and manufacturing. If you need more low-end, get multiple subs and set them up properly with the guides you can find online.
@@iliketoast-q9b yeah, figured as much! I'm using diy line arrays with quad 12" subs. Now the room has the most scope for improvement. Figuring out the cheapest way to make effective acoustic panels is almost as much fun as building speakers 😉
Those 805s in baby blue with silver tweeter are gorgeous, wish one could buy them in this combo =)
GamuT a.k.a. Just give them a call and they'll do it ;3
Excellent 👌
12:04 They use a diamond dome to be able to present the finest details in music and then 16:21 they use ferro fluid to wipe out some of the details again... Okay, to be fair, the material of the voice coil former also plays an important role in that.If it's made from aluminium it's also decreasing detail.
Even the lightest racecars use shock absorbers with their springs. Damping gives you /control/ over movement in a passive mechanical system.
@@DanielFSmith : I'm sorry but your example doesn't fit here. In a car you want a smooth ride. The electrical equivalent would be DC. In a speaker movement is the main purpose. To use your analogy: I want to experience not only every bump in the road and each small stone I go over, I want to feel every tiny bug I accidentally crush under my tyres. I want the finest changes of the signal to be presented to me. That's why I dont want a _controlled_ movement.
@@mariusloubeeka5810 When you ask your mechanic for more "road feel", would they install performance shocks or weaker ones? Sure, the damper removes sound energy. That's what you need! Look at/measure the resonance curves for undamped speakers as you bounce down the road. (Would be a good topic for your podcast, in fact ;-)
@@DanielFSmith : As I said, the car example doesn't really fit.
My speakers (link to one of my videos about them below) do have quite strong cone break-up resonances because they have stiff diaphragms (beryllium dome & fibre-reinforced paper). That is also the reason why all resonances are shifted to higher frequencies (woofer: >5 kHz, tweeter: ~30 kHz) where they are either filtered out by the crossover (@ 2 kHz, 3rd order) or in a non-relevant range (>22 kHz).
I dare to say that they can compete from let's say 300 Hz to at least 40 kHz with any B&W diamond speaker. With a good soobwofer even below 300 Hz.
Thanks for mentioning my podcasts! I think I already said something about that topic in one of them.
My _Illuminata 15_ speakers: ruclips.net/video/gMyE3SUvSeM/видео.html
@@mariusloubeeka5810 I'm sure you appreciate that a non-relevant range is only non-relevant if everything in your system (cone, enclosure, room) is perfectly linear! If you get enough energy accumulating at 22kHz anything can start to resonate. You're only really safe when the air becomes your attenuator (at the relevant distance to the object).
Mygoodness. The depth of engineering is Phenomenonal! Unfortunately, I'd never be able to afford these ever and will have to go with my Japanese/US combo.......
i knew the 800 series was good after B&W sent me a DVD with all the info like 10 years back.... but my god i didnt realise the engineering that went into them... these things are sooo sweet!..
but seriously overkill for anyone who isnt an audiofool!
"Now our smallest model of loudspeaker, the 805..."
That kinda tells you all you need to know, if you're thinking of buying a pair of 683.
I love my 601 s2's with my HK amp. My dream speaker is the 802 and some day i will own a pair👌
I've heard that the diamond tweeters has a high weight disadvantage and that's why more high end speaker manufacturers don't use it in their monitors. And that Beryllium is a bit harsh. Would the Kii Three's gain anything by using super premium drivers? They seem to be the ultimate rated monitors/most accurate yet they use $70 third party tweeters in their $30k speakers.
So basically he's saying my brand new 600 plebeian series speakers have crappy magnets, sheet metal tweeters and a cabinet built like an Ikea flat pack.
yep but they still sound great :) (imo)
Yep, you get what you pay for ;)
... greater than the sum of its parts. 🙂👍🙏
I mean, they sound like it - the old one did anyway, not sure if its changed since I heard it. But people seem to like it.
Exactly what I was thinking...
Love my 702 S2's but wish I could afford 800 series
For money 800 serious you can't buy much better speakers or can build custom much better than BMW is only 90DB for the money it's a garbage
I dream off the 800 series pretty much every night maybe when I get older and am earning more I might be able to afford some I’m using the CMS2 range at the moment not bad
@@rustystofan1740 this is hilarious
I love my matrix 802 S3
I think I'll keep them.
Hopefully this will help improve the failing tweeters in most dm speakers
Is this production still in the UK? Worthington? Or has everything been shifted to china?
i like this orange version !
Ultra quality
I want an 804 D3 in that green or blue, stop with just the white & black!
Paradigm persona offers those color options
Why the cameraman is filming his chest all the time (more than 5 minutes)?! 12:00
It would be fun to work in a place like this, creating beauty every day.
puts the neo magnet near his phone?
now this video actually explains the insane prices
What material do they use for the cabinets (stated in the beginning of the video)?
but why copper coil on the tweeter, Why not aluminum, which has a much better weight to conductivity ratio??? it does not make sense. Is it because the copper coil will be small enough for the power rating?
I love the 804D3
That nigga is a pretty good salesman.
This must explain Why I have binned the new cm 9 and do 600 s3 for yamaha ns d 40 and roksan
Garret could blow this up in 1 minute, great video very interesting 👍
ok, are we to see 800 series in that orange, green and blue?
FERROFLUID! SO COOL!
Love it!
Why is it that B&W only show their factory in England that make the 800 series and not the factory in China where other stuff is made.
agzman71 Because that’s the factory I was invited to tour. I doubt I would’ve accepted an invitation to China, that’s a lot longer flight.
Because the China factory is probably shit lol
@@Squishmallows24 probably, which actually means you don’t know?
WOW!!! I'M SOLD!!!!
7:40, gonna copy that my cnc . hehe
Is it advanced space ship we need or a simple pair of loudspeakers?
Nice!!
How long was the flight to China?
Maybe next time. The company does build some of the speakers in England.
🤣🤣🤣
What are the making?
So, the 800 series tweeter's voice coil is surrounded by a ferro-fluid material to dissipate heat into the aluminium structure/heat-sink; that's going to introduce damping. It would be interesting to see the FEA models of the tweeters (I assume they do FEA on the tweeters as well as on the cone designs) since a traditional second order ODE of the form x'' + (c/m)x' + (k/m)x = some function (m=mass, c=damping coefficient and k stiffness) would be too simple. There's an idea for a future RUclips vid: the underlying modelling work carried out for the tweeter in the 800 series.
The ferrofluid will evaporate - leaving behind nano-magnet-dust (that's when they start sounding funny and burn out). KEF tried ferrrofluid designs lang ago. Owners will need to get a refill from time to time
I really like my m&k's. Haven't heard the b&w's.
I really like The President of the US. I haven't heard about Trump.
Ok so They press it to make the shape. I was always thinking they carve baffles from wood. This way can whatever shape they desire, using designed pressing tool
He sounds like Delboy from the Trotters Industry;) Is it me or did I see a toilet seat in there? Actually I have an 805D2, it does sound good.
Maybe he can explain why all of my tweeter domes have collapsed? I have 4 cdm speakers and all for have collapsed tweeter domes.
@MAD GRUMPYMAN Yes. For the price you pay for these speaks I am shocked that this has happened. And no I didn't have kids for 10 years when these got pushed in so kids are not the culprit. They collapsed on their own from used from some strange reason. The center channel is the only one not caved in and I this that is because it is the least used.
@MAD GRUMPYMAN I lived in So Cal and the speakers where there for 10 years until I got married. For whatever reason the tweeter covers got removed from several of the speakers when I moved and were lost. I just ordered new ones. They have been missing for about 15 years and I finally got tired of not having them. I found a B&W website that sells parts and ordered the tweeter cones also. I love these speakers but my wife hates them. If I die look for them on Craig's list because they will be sold before I am cold. LOL
Thank You and enjoy. Also the reason I said it wasn't kids was that I posted before and people always says it is kids who poke them in.
My kids after I got married used a crayon or something on one of the speaker screens but that is the worst thing they have done to them.
@MAD GRUMPYMAN I had the speakers 10 years before I got married. They were pushed in before I moved to my new house.
One word: clipping
disses my beloved 602 :(
803 D3 soon come :) heck a 606 i'll be chuffed with
Wow
I still don't understand why Bentley is written on the trash can!
amaizing
the problem with his logic about tweeters is: you're limited to the frequency response of the amplifier (i recognize a class a/b is gonna be able to play higher than class d, but upper limits is probably 40k), and the upper limit of frequencies that instruments can play is like 16k, so even though a record is capable of playing 50khz, the amplifier might only be able to play 20, and the music itself will only have up to 16. 20 is basically overkill, 70 is just to show off
Its always good practise to operate a driver well away from its break up point. Music harmonics - especially a pipe organ, can go as high as 50 kHz. Ok that is besides the point. Assuming your parameters then its nice if your driver breakup is 2 or 3 octaves away from the highest sound its expected to do. So 16 kHz for your music - one octave higher is 32k, two octaves is 64k.. so this tweeter is really only offering 2 octaves of safety. When a tweeter hits break up, the peak resonance is pretty nasty. Better to keep it a long way away.
@@theprof291166 Feeding a tweeter frequencies above 20 kHz (which is already very generous) is pointless and needlessly heats up the voice coil which introduces distortions and can lead to driver-failure at high volume-levels. Unless the resonance is within or right above the tweeters intended frequency-bandwith it will be completely inaudible anyway, so this supposed 2-3 octave safety factor is complete overkill.
450lb speaker out of aluminium? B.S. Krell's Lat 1 was only 250lbs and about the size of the 800 D3 if not larger overall.
There are many speakers and then there are B&W.
You mean two sheets of wood are stiffer than one? Amazing! They should laminate many layers together and build houses with it. Golly!
theres some not overly well done camera work in there. But other than that, good video, very interesting
Norml B Sorry about that whole "camera aimed at shirt" segment...
@@avsforum never mind, thank you for showing us the factory ! I wouldnt do much better instead ;-)
Amazing that there is a market at this price point.
cheap for what they do...
I like B&W's engineering ,but they exaggerate and overstate things.
I always like how they look, but the sound is not for me.
likewise here. I like the look and dont mind the overengineering, but i dont love sounded speakers, like B&W definitely are. Perfect speakers in my opinion are very neutral, like studio monitors or a decent pair of Nubert`s
@@chewieone1064 Actually, B&W are extremely neutral. That's their calling card. And that's why some people don't like them because they're too stark. They don't sweeten the sound like, say, a JBL, which some prefer. To each his own.
You know , Magnet is not a Premium component , its actually low grade stuff . Because Magnet loses its magnetism on impact and distortion . And what is a speaker its a vibrating component . The Best speaker uses Electro Magnets , now you supply the power not the magnet so the distortion in the magnet is no more and is transfered to your power supply , and you dont care about that . . While you are at it you put in few extra things , like Servo control . This is something i would expect in a 30K speaker , and will do more for you then that Diamond tweeter playing at 50khz. And it wouldnt cost that much , nothing . And there are more things but not to overdo it here .
There is no appreciable loss of magnetic field strength at normal operation after years of use. Even at really high-power levels at which the voice coil fails you are usually not reaching temepratures high enough around the magnet to cause demagnetization. Hence why busted drivers are regularly reconed and re-used in pa-systems which get fed kilowatts of power rather than a few watts and at most a few hundred watts in home-use situations.
@@iliketoast-q9b you didnt understand . there is magnetic loss as soon as you kick the magnet , try it at home , actually you dont have to do that you have online people that have done it , when magnet is kicked it losses its magnetism , let alone after years of use it becomes softer less clear sound , you really dont know electronics i see that , and they count on that . As Soon as Voice coil pushes the magnet it looses a percentage of its strength , and that = distortion .
You know what also introduces distortion , filtering , those Analog 100 year old crossovers being able to filter at 12dB per octave , that is ridiculous , hence below 12dB your tweeter and bass play the same tune , and Tweeter being smaller reacts faster , and then you have phase issues , that is why its PARAMOUNT to have cut off frequency exceeding 24dB per Octave , you know what octave is , doubling in frequency , that way this filtering and phase issues happen below 24dB , and scientifically humans can not hear the sound that is 30dB lower then main sound , so actually the best crossover is 48dB per octave of filtering , but it is also 18dB overkill , so they mostly use 24dB and this is in the ball park of 30dB.
Even in the days of Valve Amplifiers , people have made active crossovers with Valves , and each driver in the speaker would have its own amplifier , not to affect the other speakers .
because when driver works , its Impedance changes and this is reflected up on Amplifier , so your bass driver kicks , impedance goes down or up , and then your tweeter if its on the same amplifier gets more power or less resulting in distortion .
That is why it is also paramount for each driver to have its own amplifier , and even better to have each speaker with its own power supply , and even better have those speakers connected to Power Conditioner , making sure that it always gives 110/220V because , as your speaker works voltage varies depending on the amount of current pulled , or the Load , its Ohms LAW , so to get around that , you get Active power supply for your speakers , that all have their own amps for each driver , and active crossover with at least 24dB per octave , ideally at 2khz give or take .
And that formula , being the best is employed in Studio Speakers where Clarity is of great importance .
For mixers to hear their mixes properly , and so on .
Only after all of this has been satisfied you can enjoy your Beryllium Tweeter , putting it on a passive speaker will not even work as titanium one that has its own amplifier .
As you may have noticed i am Electrical engineer so i chose that 19 years ago , its Behringer Turth B2031A , they worked for 19 years and are still working , they have even been outdoors on rain at partys blasted at 100% , but they have the limiter built in so no mater what i do , i cant blow them .
Actually i was planing to make a video about them , for im sure there are not many 19 year old Active speakers out there that have never been turned off , they are always on .
You know why ? Because Amplifier circuit is a passive thing , has no moving parts , only thing that damages it is change in temperature . Leave them ON , tempreture is constant and there is no damage .
That is why they work still after 19 years , but they do give a bit softer sound due to magnets being softer now , and rubber being softer , and all that .
Capacitors being dry , things like that , but i dont want to change them , i want them in condition they are , untouched .
@@dedskin1 First off, congrats on your old B2031A still going strong, they're an awesome speaker for a very affordable price, I've recommended them often, but prefer to build my own speakers. If it ever dies on you, try the JBL LSR308 or Presonus Eris E8 XT.
I'm a material scientist, former ee-student. Sorry, but what you wrote there is just plain wrong in so many places. You don't seem to have a proper grasp of system-theory or magnetism for that matter. Also learn the difference between the qualitative and quantitative.
The induced magnetic field from the voicecoil interacts with the magnetic field of the ferrite magnet and that potential energy is then transformed into kinetic energy by moving the voice coil, NOT the magnet-structure. Permanent magnets have been used for decades with great results and there is no appreciable loss of force over time as long as you handle your speakers properly. Heck even in live-sound you don't see the effects you're describing, even though pa-speakers need to be hauled around a lot, taking a few hits here and there. I've build my fair share of both hifi- and pa-speakers and almost none of what you claim has been my experience.
Now I'm a fan of active speaker designs myself, though I highly prefer DSP-solutions to opamps. But what you said about crossovers is just wrong. Both a high-pass and low-pass introduce positive group-delay since the slope of the phase changes. So while you may not hear that in the tweeter's signal down low, you will hear it from the midrange since it has a low-pass matched to the tweeter. So no, a 48db/oct-filter is not necesarrily the best option, especially when crossing over around the most common 2 kHz-range where our ears are most sensitive for gd-distortion.
Also dome-tweeters are hardly the end all be all, not even with a diamond or beryllium dome since they only push the dome-breakup-mode up higher, but they beam about just as much as a silk-dome and don't go low enough to stay out of that sensitive midrange-bandwidth above 700 Hz or so. And yes I have seen more measurements than I care to remember where this was obvious.
@@iliketoast-q9b let me tell you something , there are many speakers that are good all that are made with active crossovers and amp for every driver , boxed well leveled well , there are many , like Mackie 8s , Behringer 2031a being a copy of it , but Mackie has SMPS power supply , while Behringer has Toroidal transformer , and do you know that Transformers are better , because they react faster to changes in load current demand .Yet Mackies are more expensive , because people dont know what they are buying , 90% of time .
Everything ive said is based on my experience , a long experience since i have B2031A for 19 years , and that is only 5 years after i finished Engineering school .
The magnets lose their strength no doubt about it , mine lost 30% over that 19 years .
And it doesn't matter if you use kinetic energy or electro magnetic energy .
Makes no difference ,
It is Electromagnetic force either way , becase on Atomic level , there is no touching , nothing touches the Magnet even if you kick it with a hammer , they dont touch .
So Voice coil being an electromagnetic magnet does so to say Dance with the Magnet , its not all perfect .
This is measurable ,you have parasitic currents , parasitic magnetic currents , this is all reaction of electromagnet with a magnet . That is made by heating it then applying Electric field .
You remember in Shop when you buy something and the clerk on the table demagnetizes the holder ?
Everything i have said is known , its nothing new , there are Servo Drivers to fix the issue of magnet and coil dance .
And JBL 308 do not have a separate amp for the tweeter far as i know , i wont google it but i think they dont .
I am not fermiliar with 8XT
I am familiar with coaxial design of Fluid audio 8 inch , it really does sound like you have head phones on .
this may be good for some , bad for others , but it does present Stereo Image better then B2031A due to box design , rest is i think the same . one being Coaxial the other 2 way vertical .
If you think im wrong and magnets do not lose their strength then i wont stop you , i know they do .
And i also know Voice coil and stationary magnet do play a dance , once you can write books about , there is much to say , but is irrelevant at this point .
The most important thing in Sound System is not the System it self, but its positioning , the Room they are in .
That is why B2031A is a near field monitor , made to be listened closly in small rooms , there are models made for bigger rooms .
And there are models made for Hifi experience .
But you must know that Human eyesight is garbage , we cant even see colors correctly without having something to compare it to , our Ears are even worse .
So one should never base his opinions on what he hears , he must know what to listen for and that comes with knowledge , when you know ever corner on the speaker box is a tweeter on its own due to sound diffraction , then you know Egg shaped boxes are the same , but also expensive .
And i fully support DIY projects , but they are almost always more expensive then just buying what you want .
@@dedskin1 So what, 30% lost over 19 years is totally fine. You just lose a bit efficiency and maybe your frequency-response changes noticably. But you're an EE, so you can fix that easily, especially since it's active. I don't have the time or patience to read that much poorly formated text though so please fix that.
The JBL LSR308 does have a seperate amp-channel for each driver, but on the same die. EEV-blog did a tear down a few years back and experts who know more about audio than you or I combined have also said those LSR308 are about as good as it gets for the price. The E8 XT and a few others are also very good and similar in design of course.
System-design is the most important actually, even more important than driver selection. Of course it should be done with the target, i.e. the room, in mind.
I just built a double-18 sub for a pa-system a few months ago btw. Cost: just under 1000€, Celestion-drivers with ferrite magnets, plywood-cabinet. Performance: Worth about 4-8 times that, comparable to a KS28. Now of course if I were to pay myself an hourly wage it would be much more epxensive, but it's not like I would work and earn money if I wasn't building speakers in my spare time. I would be doing something else for fun and not for profit.
Oh and my Crown XLi 1502 has a SMPS and can deliver plenty of power to my sub and fullrange-speakers just fine. Go ahed and have a look at audiosciencereview.com and see the measurements for yourself.

B&W speakers definitely come with grills. I think it must be that they find it easier to show them when they are off. A lot of people also choose to leave them off. It just depends if you have pets and kids. Though cats just love speaker grilles !
I would like to think that all employees at a very steep discount have a nice pair of Bowers & Wilkins at home. I know I would .
I could be wrong but I doubt most of the employees I saw on this video (apart from Andy Kerr) would have the finances or motivation to assemble a system which included an 800 series speaker. You never know though..
I didn’t get the comparaison with an exotic car better performing at 100kph than a cheap one:
Il the speaker is rated +/-3db between 20hz and 20Khz, this means that it performs at its best within this range... why would we need to go much higher if that doesn’t improve the audible performances?
It DOES improve the audible performance, that's the entire point. A point of failure is never 'immediate', its gradual, so the closer you get to it, the more small issues will start appearing, which is why you want to move the point of failure as far away as possible.
Put it this way: if I asked you to run 24+ km/h, you probably cant do that for very long, because its close to the average human limit, your failure point, you get winded, red in the face, sweaty - not very "composed". Most have to go to almost half that speed, to be able to keep it up for a long time: 13 km/h is a fairly normal marathon speed. So your "comfortable" or well composed speed is only half of your max speed - same with the speaker, in theory, to reach 20khz comfortably, you often need a much higher maximum limit.
And ALL THIS TALK is the reason why home assembled DIY speaker kits WILL NEVER BE HI-FI resolution sharp, clear, deep and inert. Nuff said
For the 800 I've not money, but last month I had bought the 702 S2 My
TT Rega 3 with Exact and my ampli-McIntosh are very happy.
P.S Sorry for my English language, but i am Italien.

Amazing , but why the sound is so bad. There is a 🎤 which make the surrounding area sound quit.
All this and it still sounds like music coming out of a box!
"A fool and his money"
That's like saying a CRT and an OLED TV both look like light coming out of a box. Stupid.
i'm convinced if you were a multi millionaire you'd still buy an integrated stack system from matsui... right? :P
Three comments: First, I own 804D3s. 1. Disappointed the tweeter tube is only there for show (as well as holding the tweeter). The original "Nautilus" premise was to let the tapering tube dissipate the back wave so it couldn't reemerge full-strength from the front (again). The demonstration clearly shows total tube blockage directly in back of the diaphragm. 2. The presenter mentions "safety concerns" regarding the speaker tipping over (from being top-heavy). I provided platforms for my 804D3s as it was clear they could fall over with minimal assistance ($325 out of my pocket). B&W thoughtfully provided platforms for their lesser model tower speakers. 3. Funny how the factory affixed some kind of paperwork directly to a driver cone with paper tape. More concern for the finish than the part people actually buy the speaker for?
P.S. Wondering if the factory ever tried the plywood pressing procedure in a vacuum chamber? Could probably get a few more percent of stiffness with the glue getting sucked into every last crevice? Love my 804s BTW.
Kenton Kirkpatrick the tweeter tube is aluminium, almost sold aluminium, is thee primarily for heat dispersion, he says that, and heat dispersion is critical! In driver components. The front baffle on my speakers have a 9mm think aluminium plate that all drivers are mounted too, for this very same reason👍🏻👍🏻.
Kenton Kirkpatrick but yes, they should have shown us at least, the paper taped to the driver, I cringed😂😂😂. Nobody would ever get close to my drivers, and I certainly do not handle them myself, that was painful to see😂😂
I forgot to mention the "ferro fluid" which is used to cool the tweeter voice coil. Anyone know the shelf-life of ferro fluid? My understanding is ferro fluid dries-up over time. Can the ferro fluid be replaced or must the tweeter be replaced? Inquiring minds want to know...
Kenton Kirkpatrick well, I’d suspect it’s a life long substance, as he mentions that the cooling properties of it, means the tweeter never gets too hot and deteriorated over time, he goes on to say that because of this this sound always stays the same, throughout the speakers life. So I’d suggest it would be a life long substance based on this...👍🏻👍🏻
@@kentonkirkpatrick5225 Life long ferro fluid. Wow! Meaning you never change the oil in your car?! If it dries up you have two options #1 New Ferrofluid or #2 New Tweeter.
It's such a shame to paint over wood that beautiful.
He is hifi’s answer to David Brent.
Dynaudio Contour 1.3 mk2 kills my B&W 805S
I cant stand the sound of B&Ws but their build quality is impressive.
Great video!😣
Where are all the Chinese people?
This guy is putting me off buying my 606s.
I'm not sure if this man really knows what he is talking about...
Why companies like B&W and others today's days selling basically I can not say lowend but midrange speakers as High end speakers for lots of money like 15 or $20000
14:20 Guess he doesn't know much about cars 😕🤦🏻♂️
What he should be saying is Koenigsegg. Not Bugatti (who's copied loads of Koenigsegg designs) and not McLaren.
Nonsense.
Get some JTR 210RT's.
And after all that no sound test video .computer says computer says computer says
WOW!
