World's Second Best Speakers!
HTML-код
- Опубликовано: 8 май 2019
- We construct a pair of large Voigt speakers. I explain the principles behind ported, transmission line and horn based loudspeakers, demonstrate these speakers in our anechoic chamber and use constrained layer damping to build an enclosure that is superior to commonly used MDF.

I swear, these videos just keep getting better!!!! This is definitely my favorite channel, I'll never stop watching! I love the speaker and sound videos the most though, they're my favorite, so it's no wonder! Keep it up!
bless you for knowing grammar and spelling
Agreed. Scientific method through-and-through! I love the long-format, quantifiable, and iterative results. This work puts so much truth back into practical engineering in sound... helping to rectify more than two decades worth of audio-mythology on the interwebs!
"Precisely" !!!

Im looking for a Circular coopper tube video. where a magnet is spinning inside. and powering up the outside of the copper tubes. while spinning freely . because of some kinda gas imploding and exploding inside the tube. and than suddenly creating a ROYAL RIFE Telescope thingy .20000x magnification! . See the DNA of a acient relic. :) me
The tone generator being left on for 5 minutes was a test to weed out those too weak to learn the secrets of sound design
It's absolutely nothing to those of us with tinnitus. **laughs in -6db**
Hahaha good one! But seriously if he put a notch filter on that in post processing that would have been nice...
Plot twist, this guy is actually deaf.
@John D ive found a man not worthy of enlightenment. The sound gods will smite thee
No kidding, it was driving me nuts. It was such a wonderful relief when he finally turned it off!!
This gentleman is willing to share all his knowledge on sound and speaker design and ask for nothing in return. I find that extremely decent and humbling.
He might be NWAV guy. 😂
He gets some return from the ad incomes which are very much related to amount of views.

Thank you for being the 1st person to describe to me how a speaker cone and enclosure actually works...in a clear yet substantial and succinct manner.
Except he didn't.
yeah about an hour worth of technical bs to explain what everyone doesn't need or cares to know.. $20 bluetooth speakers $10 earpods slaps, its 2024 guys wake up we don't need bulky electronics when we have mobile tech.
You, my friend, are a layman's dream instructor! You've helped me, in retirement, re-discover a forgotten passion! You are now part of my morning informational exercises. Thank you!
This is the most comprehensive and relevant speaker building guide I've ever seen! Really nice work!
Wow, thanks!
Oh, hi Ben! Nice to see you here
well fancy being able to comment on two of your subscriptions at the same time.... This kinda confirms that my choice in subscription is correct and true... Feeling all warm and fuzzy right now LoL...
Applied Science I agree! As a physicist and fellow Gaucho Alum, good stuff Tech Ingredients!
Please also do more acoustics videos, they're fascinating.
Legend has it the tonegenerator is still running 🤯
yeap, 3 weeks later after you posted this can confirm that it's still there 🙄

Best Comment Ever!
You win the comment thread with this one.
This was an EXTREMELY well explained video of so many different scientific and engineering phenomena - a big bravo for this effort! It takes a special person to be able to explain these concepts in language that can be easily understood.
Thank you!
Best explanation of impedance matching that I've ever heard.

Thanks for sharing this priceless knowledge and for undergoing such a massive undertaking so I could build myself some impressive speakers for “comparably” “cheap “ and not only appreciate what I built and how it sounds but understand why and how it works and sounds the way it does. My Subscription payed off in a big way thanks!
The sense of pride at the end was priceless. Thank you for sharing your expertise. Best explanation of phasing I’ve ever seen.
Seriously, all my 57 years life waiting for this kind of physics explanation and practical uses of the science implicated. Thanks Master
Exactly. Damn, I wish I would've had him as my all of my science professors... I might've actually paid attention and learned something.

@@wazzup7238 You need to get out more ;-) I go through so much bull shit every day...
Wow, wish I had this info back in the 80s when I was in my audiophile phase. May have to revisit those days with what limited equipment I have left over. Great video sir!!!
Awesome,clear concise delivery of high level knowledge...delivered in such a perfect and interesting manner...we all wish we could have had teachers like this noble man...would have made an extraordinary difference to attention at school. Greatly appreciate this teacher.
I finally figured out why I love this channel so much. It makes me feel like I'm back in a university physics class listening to a trusted professor who makes complicated things as clear as glass.
I had one such professor throughout my entire Masters and Ph. D. programs. I never could tell what they were talking about or even why...and I worked hard. I truly envy anyone who had a guy like this teaching them.
I had a really good physics professor (undergrad) and I just "clicked" with his teaching style. Aced that class. (One of the few!)
physics language non the less
As I read these comments,and such,..Almost EVERY one of them,are referring to something I ,immediately kinda giggled ..as I watched ,...lol..

Thumbed up for the ping pong ball analogy for impedance matching cones. I've never heard that before, but instantly understood the analogy. Great stuff!
Thanks!

I second that! It created such an understandable image
Thing is people have seen that desk toy with the same principles.
@@wobblysauce What thing is?
I love when people say listen how good these speakers sound… as you listen to the recording on your phone or home system
Lol but true 😅 like tv ads showing beautiful colours on your current tv
speechless at the kind of knowledge you have how practically you have used to create these one of kind master pieces! hats-off to you!
I've built some speaker boxes in my day. This answered so many questions I could never figure out on why these speaker box builds sounded like garbage cans, no matter what speaker or amp or song. I could hear it, clients couldn't and didn't care. Now I'm throwing my wallet at my screen. Thank you for your videos and being so detailed and easily understandable. This is the kind of teaching I absolutely enjoy learning from!
Thanks!
@@TechIngredients Now I have so many questions! Could DynaMat be used instead? Could you get the same damping by gluing the veneer pane on the outside? Could I take a good pair of vintage speakers and apply these techniques to make them better?
@@warrenbell950Depending on the vintage speakers, there is a good chance that the cabinet resonance was leveraged to augment the drivers - the crossovers may also have been chosen to address cabinet resonance. I generally wouldn't recommend it as a treatment for vintage speakers - either they are good, and you stand to ruin them, or they are bad, and they aren't worth the effort IMHO. DynaMat is a choice, but not as good as the 2part treatment he used - you can also pick up a similar material from box stores used to line potable water tanks - it is nearly identical and has the same properties; you can also buy smaller quantities for testing. I personally don't love VT speakers, but the science behind them as well as the wonderful detail of the video makes this a fantastic choice for an educational channel! Love it!
lost me at mar-a-lago pride. some nice info but not worth the stain on my soul. blocked ✌️
@@luminousfractal420 lol
I love that there is a channel that explains the science behind the DIY.
This is the best video about how the speakers work and the science behind it. The 52 minutes is well worth it. Thank you very much.
Ok, so this is the clearest explanation of speaker design I have ever watched. Thank you!
After watching the whole thing I feel I deserve a diploma.
Don't you need to pass the final exam, publish and defend your thesis first?
you have to successfully complete the build first

If only more humans could be like this man. Calm, smart, articulate and generous with his knowledge. Thank you for taking the time to explain all the intricate details.
My love of music just went down the rabbit hole with you, and made me hear the world with different ears!!...Thanks for showing me the matrix!!.It seems!..I started life hearing sound, became a musician and learned too feel, and see sound, and make sound, now I can finally understand it's importance of how everyting relates together!! The beautiful, unlimited, and endless effects that sound can create, for the creater, and too for the listener is magic!!...So inspired to learn more, I choose the red pill Morphious!!
I really liked the explanation of the end-effect reflection. In transmission line theory it's just talked about as an impedance discontinuity but for resonant tube design (think wind instruments like flutes) the resonant length of the tube appears slightly longer than its physical length. That high pressure node that the sound reflects off of occurs not at the exact end of the tube but slightly beyond it, which is easy to understand if you visualize the pressure changes in the air and the non-negligible response time for the surrounding air to rush in to fill the low pressure void emanating from the end of the tube.
Near the end he looks so smug and proud with what he has created... and rightfully so, because this is excellent work!!!
I have Parkinson’s and I need new hobbies and new interests for my brain. This is my favorite channel on RUclips. Occasionally, I have to rewind the video (i’m not sure of the proper nomenclature but I have to rewatch certain sections to understand them!) to understand the concepts but it’s time well spent. I tell all my Smart/curious friends about your channel… It’s Amazing and I love your videos!
Look into music therapy as relates to Parkinson's. Music therapy can help with many aspects of the condition. If you play an instrument, by all means continue at it. The biggie is rhythm. If all you do is knock about on bongos or other hand drums with musical accompaniment, it will help. (It helped my Mom a lot.)
That is the proper nomenclature, Ralph. You're one of us, now! ;)
Fantastic speakers! it must be extremely satisfying to build such awesome speakers. Thanks so much for sharing!
Thanks for the great content. Im in a college class about vibrations. I think its interesting how vibrations and damping are understood in a real world example. (oscilloscope) Thanks for reading all the comments and have a nice day.
"I have a lot experience with the marine plywoods and I would highly recommend them."
This one sentence perfectly encapsulates everything I love about this channel.
“Marine plywoodS” THERE’S MORE THAN ONE?!? HOW MANY MARINE PLYWOODS DO WE NEED?!?
@@DanielBrownsan Far more than you might expect. But don't worry, the final tally is based on sound engineering principles and backed up by solid research.
Please tell me how make good box for speaker pioneer size 6/9
And what best wood use for that
@@ahmadalardah4198 Get the T/S parameters for your speaker, use software like WinISD to calculate box dimensions, and then use MDF/HDF/high grade plywood (your choice).
Maxican When I was a teen I made a large rectangle cabinet for two 15-inch drivers out of quality plywood... Didn’t do any research or even know what I was doing, just hacked it together in a few hours and it sounded brilliant to me :P I guess I was too young and inexperienced to have a discerning ear for quality audio.
That look of victory and glory as the master stands cross armed nodding his head in admiration and contentment is my favorite part. I've probably watched this video countless times and it never gets old. An epic upload that will live on forever.
this is simply a masterclass on sound... Just sublime... THANK YOU!
Thanks for playing that loud test tone all the way through your explanation. Good work.

Man, thanks for doing this! Absolutely amazing!
I’m going to have to build the cabinet my own way, but you’ve given me enough material property requirements to do so.
Did you build these how did it go and how do they sound
I would have liked to have you as my teacher in my younger engineering studies.
Jean Pierre, J,ai écrit exactement le même commentaire!... longue vie à Tech Ingredients !
Doctorbass 2 saying the same comment for the guy means he is really a good quality teacher.
SAMEEEEEEEEE
yeh, then id probably actually learn somethings. the "looks" of theese videos is kinda "gray" compared to most "youtube" stuff, but if you blink or snooze a secound you miss something valuable! is he doing this by heart without a script? thats just crazy
bunnlose you can hit the replay key if you snooze out! This guy knows what he is taking about. I’m not sure, but you can verify.
your face at the end looking at those speakers looks so proud !! and you should be really proud, beautiful speakers... i love them ❤❤
Yea, hes proud smile put a smile on my face too.... good job, really good!
I literally said; aw, he's listening to his babys!
Came here to say the same thing. I don't need to hear the sound. Your face tells the story.
Just brilliant explanations and demonstrations. Really liked the demonstrations of vibrational characteristics. Great stuff man!
Your Smile when the music starts at the end says it all. These are amazing speakers.
I love how proud he looks of the speakers when they start playing. :)
my favorite part.
I would be also.
It is just a shame he did not pick a better piece of music for the demo. I found the official download for it and the bass is clipping making it distorted.
was about to write the same comment
When?
"And that creates what's called a frequency comb, of spikes and troughs in the amplitude of the sound"
Me: Ah excellent.
"That's not a good thing."
Me: oh no.
😆 that made me laugh so hard
Brilliant comment Josh! Cracked me up! Kinda sums my understanding of it- I understand, but I don’t. (But I mostly do.....I think)
🤣🤣🤣
Larry Patterson Exact, your life is totally annoying Larry.
This is the best comment I've seen in months
I love this channel. I swear the tone generator was left on for comdic relief. I was giggling. He kept going as not a care in the wind. It shows how interested we are in the videos u guys make. When it stopped. relief!!! They do such a amazing job balancing technical theory to actual real world observations and concepts anyone could replicate and understand. Plus the stuff is just cool. Whoever says science ain't fun, haven't seen this channel. I want a shop like yours.
Hi, just came across this a few hours ago. WOW! I built my first set of speakers back in 1978, they lasted about 20 years. I've used Mission 753's since with replacement drivers and x/over components, which I've installed myself. They are still working. I would really like to build these but I don't have the space to do the construction, shame. Even via utube compression, the sound is fab. Well done to you, sir. A great vid explaining the construction/design plainly and simply. One can still dream of the good things.
Kudos to getting rid of the myth about MDF being THE material of choice for speakers!
Also, great to see fullrange speakers properly used here (small cone impedance matched).
The Voight or TQWT designs are decent and easy to build, but you can also get excellent results with TML and horn designs.
Regards, D.C., creator of the Cornu Spiral Horn.
I love it. He tests EVERYTHING. Even the stiffness of MDF vs. plywood...
ikr 😝
Excellent DIY video. All I need now is a workshop, the machinery and the time to spare. Thank you for sharing your expertise!
Such excellent information!!! I'm going to build a pair of these. THANK YOU!!!
Was waiting for his son to point hysterically at the tone generator but nope. Amazing video though!
He really, really should have. It is a general problem on the channel that there is too much background, though. It happened several times during the turbine series, and now this as well.
Right... lol
It would have even been worth removing the tone in post, the following explanation would be much more pleasant. Lots of free tools to do that, like ReaFIR.
Agreed. However, since it's a fixed frequency, you can move your head around a bit to find a null (if you're listening to speakers) and make it a bit less annoying. :D
ya, you can tell there is no humor in that house. No way his son is gonna step out of line.
48:07 that feeling of accomplishment is priceless. his Face say it all..
Came here to say exactly this. True satisfaction right there.
Best smug face 🤣
im happy to see around 47:30 the smile on his face, he looks so proud and i love it. when you put alot of time into something like that you should be proud.
Wow I wish I had your workshop; those speakers sound amazing. Thank you for sharing I do very much appreciate it.
would have loved to see a frequency response curve of the finished speakers.
Bravo!
Exactly what I was thinking when it finally ended.
I would love to build these, but what did the finished curve look like? How much bass did you coax out of those little drivers?
After all, you're the one with the test equipment and anechoic chamber.
@@johnny7254 the final product's performance is still a synergistic result of the source, speaker, enclosure, room, and what's in that room, and further - how that room is constructed even plays into what "you" actually hear.
Everything resonates. Those resonances cause harmonic distortion. This means even your walls affect the tone of your listening room depending on how dense or flexible they are. ;)
@@MotivatedMetalworks You'll get no argument from me on anything you've written. Nevertheless, it is more than a mere matter of convention, that we derive specifications for speakers. It is the method by which we compare one loudspeaker to another. Even beyond that, given the level of detail and science brought to bear in this presentation, is absurd to leave out any measure at all, by which a viewer could assess the success of the endeavor.
@@johnny7254 fitting those beasts in his chamber isn't possible, so any response curve presented would be flawed.
However, he could play them outside and get a pretty good idea.
When I build speakers, I try to balance the drivers across the spectrum, and crossover points based on where the curves are most beneficial at the natural roll off points. Once that's done, I design the enclosure to meet my goals - is it a sealed box with no deep base, or can I tune a port to hit another octave lower?
I don't agree with the channel's logic or validity testing on material weight/stiffness as the accelerometer was measuring an impossible occurrence with the thump test. Also, floor weight of speakers is a moot point for most applications (outside of aircraft, boats, and possibly cars), while size is often a critical design element. Doubling the speaker walls increases the outside dimension, as the inside is a calculated and highly constrained space. In most cases, MDF with proper internal bracing will outperform the same thickness plywood, while benefitting from a lower cost.
Transmission lines and horns in general are the exception, but he doesn't state this or why - you can't brace a horn like a ported box, because you'll fuck it's performance up. So in these enclosures, you need stiffer materials.
@@johnny7254 Something else comes to mind when thinking about this video.
About 30 years ago, Popular Mechanics had an article teaching the reader about transmission tubes, and how you could build a subwoofer out of a 4" Realistic (Radio Shack hadn't fallen off their original business model yet, at that time) woofer and PVC fittings.
What the article failed to disclose is that while the micro sub would hit 40hz, it was anemic and not musical sounding doing it.
Planars, infinite baffles, and line arrays all have impressive sonic qualities while also suffering some significant drawbacks. Voigt enclosures aren't exempt either, as they tend to lack authority in the bottom end, or as with folded horns, end up being gigantic enclosures to play through the whole spectrum.
Voigt's share a commonality with planars and infinite baffles, in that the linear distance from the edge of the cone and the port will have a direct impact on where phase cancellation occurs.
At the end of the day - there is no perfect speaker enclosure, and we need to balance our designs with regards to perfection and reality and hope we can afford the point we wish to land on between those two ends. :)
This is the most comprehensive cabinet resonance discussion I've ever seen. You answered questions that I've pondered about for 30+ years. I absolutely loved your approach, your attention to detail, accuracy and material cost. Thank you soo much, what a great start to my week!
Beautiful, I like the grin at the end. Awesome sir🥰

This might just be the best channel on RUclips. No hyperbole. The quality of information is top-notch. The speaker is articulate and entertaining. Everything is presented in familiar terms such that even laymen like me can understand. The sincerity behind this channel also adds a lot; I genuinely can't help but smile when he says, "Have a wonderful evening. Good night."

Excellently explained the science behind speaker building.I salute this gentleman, deep knowledge and explained in such simple language
Amazing Video, I stumbled across your channel while watching Congressional Hearing videos. What a nice break... I was discussing Voight speakers with a friend a few days ago, I collect vintage audio equipment. fell down an enjoyable rabbit hole. You my friend are an extremely talented and gifted man, best online professional with a very impressive delivery of some rather technical information. It's obvious you enjoy what you do and enjoy presenting it to the world even more. This is the sixth video I've seen, Subscribed after the first. I'll stumble back in again from time to time Thank you.
What a great video. I'm going to make this compulsory viewing for my acoustics students at the Academy of Sound Engineering. Thank you!
Just for future videos, you should turn off any terrible noises when you're not demonstrating something with them.
Otherwise great video, I'll have to incorporate some of these ideas into my sound exciter speakers you convinced me to make.
PLEASE...PLEASE...PLEASE
Please!
I would have posted a reply but my roommate killed me for allowing the tone generator to continue...
hugely this. :) I wasn't gonna say anything, but since it's a thing now, I'm adding my support for turning off the signal generator once you've demonstrated the effect.
Yeah that was brutal
Thankyou, I have been interested in high end audio for several decades, both making some diverse stuff and spending far too much buying stuff 😂 .. but this is by far the clearest deeper explanation of this type of speaker I have come across
50 years working in audio broadcasting and just now I understand the physic phenomen... Thanks a lot!
i am a carpenter, and that is the cleanest workshop i have ever seen...even in sci fi movies ..great vid !!
Respect! You deserve complete unreserved respect for your research, work, results, and freely sharing it. Thanks!
This was so Much fun to watch you in your enthusiasm... For a job well done and information well shared.bravo
Extremely fascinating, you are a very good teacher! One of if not the most detailed builds I've ever seen. Some concepts were slightly over my head but I am sure if I watch it a couple more times I will get them. A+ instruction
?? There was no "build" in this video.
As an old speaker builder I learned a few things I can use but really appreciate the manner in the way you demonstrate the principles! I enjoy learning the science behind the project and you did a great job teaching us just that! A very warm "thank you"! Definitely subscribing!
I now understand the man has a sense of humor- otherwise he wouldn't have let that tweeter drone on.
I think he may have noise induced hearing loss. Doubt he noticed that he left it on.
Yah um, as smart as as he is, and as well as he explains it all, he's also, obviously, quite hard of hearing.
It was incredibly difficult to pay attention to the info with that loud, high pitched tone going on.
Psshhh I was enjoying the video until he used that thing. I turned it all the way down and could hear it 2 rooms over
I couldn’t watch after he left the horn unit blasting out. ☹️
To say the worlds best speaker definitely leaves him open to criticism these are very good but can be outperformed by a full range electrostatic there is one made by the stage accompaniment company
I guilt a pair of Voigt Pipes very similar to those in this video about 15 years ago. They sounded very good, especially in terms of mid-range and soundstage. The mid-bass was also sufficient but could likely have benefited from addition of a sub-woofer for added slam. Eventually, I added a tweeter to add "air" to the system. Fostex produces a broad line of appropriate yet affordable drivers for this and similar designs.
I did the same and I’d like to upgrade my cheap drivers to a foster 8 inch driver. Would you have a recommendation for a model?
Excellent descriptions! Best I have read/heard!
I have been an audiophile and electronics hobbyist for 50 years, I went into the military and learned sonar and sound wave behavior because I wanted to know more. I like the way you explain the science and physics and you are spot on. You speak my language keep it up. Great job!
the explanation about the standing waves at the beginning is one of the clearest I've ever seen
I just love how during the music at the end you can’t stop admiring his speakers…well done
Amazing. At the end the demonstration sounds like a line source played thru my personal speakers. Phenomenal results.
Thanks!
If you listen carefully near the beginning you can hear me folding my arms, it's definitely real and we're only set up in a lab.
This channel is awesome! Some people might think that watching a guy talk about speakers for 30 mins is boring but it is really interesting. Keep on making videos!
You know the video was closer to an hour, right?
This is genius! A summary of all loudspeaker acoustic theories boiled down to their practical aspects and essentials. Never have I watched a more helpful video containing so many invaluable tips and techniques. Well done, congrats!
Great video.
I'm very much into mid 50s German valve radios and only yesterday decided my favourite set needed a set of extension speakers but in a pleasing style.
Somehow the Gods decided to have your video link underneath a totally unrelated video I'd just watched and now I know exactly what I'm building.
I will subscribe on the strength of just this video alone.
Thank you.
Thanks!
The single most intelligent and well-made video I have seen to date in ALL of RUclips!
Beaming with pride, this is what a meaningful life brings about, not easy but meaningful. Keep up the great work!!
I love it when someone presents a topic and they go into details on different details; they don't just know their topic at hand, but know related topics to a relevent high degree. I'm loving this video. He sounds like my mind talks on different topics. I have no idea what he's talking about most of the time, but it's convincingly expert level 11 and I wager if anyone disagreed with him, they'd better be ready with a full explanation and sound logic.
Excellent source of speaker insights for audio buffs!
I am so happy to have found this. Look at his passion at the end when he looks at his speaker.
He looks so happy at the end!!! When they start playing it looks like he's holding back a giant smile and maybe a tear or two.
After watching this great technical and educational video I am now inspired to duplicate this build. I can’t wait to start. Thank you for your dedication to perfection and great detail. Please keep it up !!
Explained very well and great instructions and video. Brilliant
Rewarding to listen to what you built, thanks for the videos you make.
I've had my Voigt horns about 30 years, built from one sheet of plywood. Good to see these get a some exposure, good job.
I love this channel!!! Imagine how differently school would be viewed if teachers were half as good as this guy. (Never going to happen, but what is cool, is that unlike the education system, the best can be shared to anyone/everyone) RUclips for the win!
Guess I was pretty fortunate, as the science teachers I had in High School WERE this good, and were such a tremendous inspiration to me that 40 years later I still can't get enough! I don't doubt my last breath on this Earth will probably happen when I'm watching a science video or tinkering with some nifty new technology.
He is smart. He is the perfect nerd!
Fascinating video. I am learning......loved the speakers. Thank you for sharing the knowledge and your design.
