Man, this video made my day!! I am not even talking about the speakers themselves, but just the vast information that was provided on testing the speaker system itself!! Your videos have helped me a lot when it comes to purchasing car audio equipment both quality and technical!!
After years of driving myself crazy with various car stereo installations. First for my personal use, then I started installing them in my son's cars got him addicted. Home audio equipment up the wazoo, everything to me was specifications until recently. There's so much BS out there now that I find the specifications mean nothing. What matters is the actual sound , do I like the way it sounds ? I may like a particular type of sound and my friend might like a completely different kind of sound . That's what I've learned playing around many years with audio equipment. Wholesale, retail building my own equipment fixing my friends Right Down the Line. I have to listen to it specifications can drive a person mad after all the research in the world you can hook it up and expect it to sound like something that it doesn't deliver. Happens all the time.
Buying from Amazon allows you to try in home and just return if you don’t like the sound. I don’t talk much about SQ as it’s subjective. Unless I hear some crazy buzzing or ringing, I only comment they sound ok to me
@@wal I understand why you do what you do. That's what your channel is all about and people love it. You also make it entertaining so it's not just numbers. Keep doing what you do.
With the market so saturated, if they actually gave specs, most companies would go under, either from just being middle of the road, or due to their gear actually sucking. So annoying that I decided to just get the equipment to do most speaker and amp measurements at home so I can have the actual specs of my gear. One thing I can say is that there is often not much correlation between cost and actual sound quality. Some very inexpensive gear (amps, speakers, headphones) can have state of the art performance, but other expensive posh brands will measure poorly and not sound good. If specs were given to and used properly by the consumer, there would only be about 1/10th the number of manufacturers.
And as for specs, they really give you virtually nothing at all. Just some vague numbers to make it look legit from the quick online preview or on the store shelf. Some of the specs are real, but companies only give the absolute minimum lest it give bad optics to the consumer. This is doubly-so now that things like Amazon exist.
@@mysock351C Agreed, reminds me of the first Speaker setup that I put in my son's car .I used the brand that I was wholesaling called Cadence it sounded phenomenal but he wanted kicker because he was young didn't know any better and that's what his friends had in time I ended up getting a him kicker amplifier and subwoofer and the such sound was not any better.
More important than junk from Amazon are the DIY amp boards Parts Express sells. They have those new KAB boards they sell. There are the others that say 200x2+600 watts etc. Nice to see if than stuff is bs or not.
Agreed besides I'm not sure how many home speakers this guy has ever opened up cause I'm sorry to say but I have a pair of custom legacy focus II there custom with a hand signed build plate on each and an extra 12 in sub on the back side. No joke the reg focus II sells for 12 grand yes 12k per pair. I didn't pay close to that but all I gotta say is for a quarter the og price or hell a tenth the og price I could build much better. All 24 k gold traces on crossover board 3 switches on x over board besides the bi amp option hell of a way to toast 12 stacks lol twelve thousand not twelve hundred lol. Open it up or buy replacement parts or drivers n it's like wtf where did that money go???? Fkrs can't cost more than 800 to a grand to build from what I can see.
@@christopherparis6841 This vid does serve a purpose. Too many gadgets on the internet with questionable specs. I just more interested in the DIY, not the (Why did I buy?).
The psu maybe rated at 18v 2a constant and does not have a over current protection so it's pushing as much is can and probably will blow up after too much load for a bit longer time..
@@Only-Memories-In-The-End Those old psus were not that much efficient . Mainly cus they have plastic body. Similar wattage & size psu with metal case runs much cooler , in few years we will see more and more ganfet chargers so i hope they cool down a bit 💀 some of them easily run at 60c when charging.
I agree the biggest selling point is the sub output. It’s not as common on cheap speakers like this. Too bad it was faulty. Easy infix though if you turn the sub in and off before the speakers. I know it requires an rta you might not have but for a speaker I would’ve liked to see how close to that 45hz it really got and an spl rating. But it was a good video. I love how your not afraid to take things apart band show us what we’re really getting for the money. And I was surprised to see you could get a 55x2 amp for $7 on Ali kinda shows you where all your money is going on these purchases. Thanks
The new version of these now have controls on the top of the R speaker, a redesigned horn-style soft dome tweeter and are 40wx2 now for the 4" speakers. I found a pair of these at a liquidation store for all of $11 and they are incredible for such small speakers.
the three mode buttons only work through a physical connection not through the Bluetooth connection, when connected through Bluetooth it uses your phone's DAC or EQ to control the sound quality and tone. Fun fact these Bluetooth bookshelf speakers can also be used as passive drivers with a standard receiver amplifier just use the connections on the back like the standard positive and negative speaker inputs but do not connect the power or any other connections to the Bluetooth driven speaker and you are good to go just control as normal through your stereo receiver...
The power supply is also rated at 120-240V @ 1.5A which at 120V makes the input power 180W. Power supplies are often rated at that power for continuous use but cheaper manufacturing techniques usually remove the safety’s and over tax the components which usually results in early failure. Would be interesting to see the power supply under a thermal while running the system limited to 36W total output and comparing it to the system maxed out.
They are abusing it quite a bit. Worthwhile to note that its audio, so the power is not continuous, but rather the peak power will be a minimum of 2X the RMS power, just due to math, with a conventional linear amplifier. The only saving grace here is that its class-D so there is some impedance matching, so its not quite that bad. I have built similar SMPS power supplies for my small amps that put out around 60-80W or so, but even the transformers I use are bigger than that entire power supply. Without any limiting for safety they will put out 200+ watts of continuous power, so that tells you that there's a good chance this thing might burn the house down if you abuse the speakers too much. The IC probably has thermal overload protection, but still I would want to buy a proper one. God only knows what's actually in there. Its probably some e-waste or something.
Interesting video. I think most of us that follow you have broad interest in audio products (home, car, pro audio), so nice when you branch out from car amps. I have a few thoughts. If your powered subwoofer has a subsonic filter, that thump probably wouldn't bother it much. Do they have any built in crossovers, either high pass no the woofers, or low pass on the sub out? I really think you ought to get a mic and show test curves on reviews like this. You could pretty easily get a pretty good idea of the output curve, whether those mode buttons did anything to the output, and you could see if there were crossovers.
Dude, you’ll dyno ANYTHING!!! I’ve been trying to avoid watching this video for a couple days now. I think I may have an addiction to these things! I need help in the form of more obscure amp dyno vids!!!
For all of you youngins that don’t know what a map is, or the joys of trying to fold it back up, a map is an analog version of GPS, but it doesn’t tell you where you are, or where you are going.
Another interesting video Big D. Keep the variety coming, its refreshing. I also bought that Polk subwoofer last year but I had to return it because it made too much mechanical noise. I bought the sony equivalent and it provided very clean, but slightly less strong bass.
I just saw these on Amazon I thought about getting them for a friend of mine who needs something in her apartment. I would be tempted to put a little bit of polyfill in those before I button them back up
If you want speakers like this but on big steroids get Klipsch The Fives powered book shelf speakers. I'm blown away by mine. It's more powerful than my guitar amp
That no way to operate without the remote, is a major oversight! They should atleast have a couple buttons on the back, power and function, something, or have an app to control it,
Now you are going to have to get your hands on a 24V power supply and re-test it! Oh and I would caution against using the supplied power supply, being rated at 2A while 4A is being drawn from it is a fire hazard waiting to happen! Those wall warts don't show up their temperature very well on the outside, I had a wall wart that was plugged into the mains but it wasn't plugged into anything, I noticed that the plastic shell was getting warm and I was curious if there was a bad capacitor on the output that was leaking DC and beginning to short the output causing the power supply to work hard even though it wasn't being used for anything... This wall wart had screws holding it together so I was able to open it. When I touched the transformer, I burnt my fingers! I couldn't believe how hot it was and yet it was only warm to the touch on it's outer shell! I would recommend to anyone who is looking at getting these powered speakers to get a power supply that is capable of delivering more current than 2A... I would even suggest to use a power supply rated for a higher voltage for which at a given volume level, the higher voltage power supply would be delivering less current and thus be more efficient.... The higher voltage will also provide more power output when the need arises... I hope that this is helpful to someone! I would be interested in seeing what temperature the wall wart get to after being used at higher output levels... Not sure if it has an actual transformer inside which you can tell by it's weight or it's a SMPS type? Who knows? But I would definitely like to see the output power with a 24V power supply! I bet that it would get pretty loud! Those 4" woofers are going to bump hard!
@10:11 - I probably would have wrapped that small wire around the amp clamp twice (or more) and divided the results by the number of turns. Also, I would like to know the output voltage of the power supply under load as a static voltage and a loaded voltage aren't likely to be the same on a cheese power supply.. Back to the video.
It is what it is, Ohm’s Law doesn’t lie, and it produced rated power. Now will it do better with a more robust power supply? Sure, odds are much better dynamic. Might even eliminate the turn off and on thump..
Your videos are awesome bro you safe a lot of time going and looking on line to only guess if it's a good deal. I always check and see if you tested any amps I'm about to buy and if it's what I want thanks for your videos man!!!!
Parallel diodes across the subwoofer output hot and ground. Spec the diodes to bypass the thump voltage figure. That or a timed relay on the signal output.
Even brands like Yamaha these days rating their powered studio monitors at 1000w even though the input powe is 90w max and so about 50w from a class d amp. Just saw two of them in a stage. The main speakers were powered by 3x 7200w class h amps 💀 the bass drop was pulling volt meter like vu meter.. at near clipping the mains voltage dropped to 200v from 245v.. 💀
Big D I love how you went threw and checked it using ohms law 🔥🔥🔥🔥🔥 another great job and well done video with the breakdown of these bookshelve speakers 👍👍👍
Hey Big D, you measured the resistance of the tweeter incorrectly. 😉 You were on the wrong side of the cap and measured the sub resistance through the parallel amp connection.
More than a hundred percent efficiency? This must be those new class X amps that Elon Musk was talking about. The thing is so damn efficient, it gets cold when you run it.
it's magic my soundbar also has a 36w (20v 1.8a) power supply it's rated 20w times 2 and 50 watts for the subwoofer output that's RMS power btw and it actually outputs it's rated power from that power supply i don't know how but it does somehow one interesting thing is that it has a very similar remote as thease speakers you reviewed and both have a 36w power supply edit: oh alright it makes sense now still kinda crazy though ngl how underrated the current is for those who are wondering i did test my power supply and got 20.2v but i haven't tested it for current (yet)
That would be interesting to know. I see other brands with power supplies like this rated 20x2 RMS which is still well beyond the 36W power supply capability
It might not give the thump turn on and off with all subwoofers. It all depends on the auto sense circuit and the timer. With the Polk sub, I would try an in line filter ( ground loop isolator ) on the RCA’s. It may or may not eliminate the issue, but worth a try.
The power supply might be the cause of the off/on thump too. A more robust one might eliminate it. Regardless one of these ideas mentioned should eliminate it
@@Only-Memories-In-The-End thanks for the reply . I just haven’t seen a good video with demonstrating and some explaining for people who might not know about products like that . I think he does a Fantastic job explaining stuff the simple way that even a beginner would understand . Plus a beginner definitely does not know about the epicenter 😀
@@Only-Memories-In-The-End he is reading the comments . And I’m sure we will see something . This is way too good and way too confusing to not make a video out of it 😃
A lot of times those cheap Chinese power supplies don't have any protection and can dynamically do double their power. I have one which can do 6 amps when it was rated for 1 amp. It'll burn itself up eventually but it can do it.
Awesome video. That's 77.4 watts! Wonder if the fets would take 20 volts at 4 amps? Thanks for going through the trouble of figuring out what we all were curious about. Cool little speaker's
Running 24v 6a on my SMSL amp, and it does a decent job with my 8 ohm bookshelf speakers. Sound quality lacks quite a bit without a toroidal transformer feeding clean power though.
I'm not surprised the PSU is underrated. It is warranted to make _at least_ 2 amps at 18v, beyond that is extra. It may overheat & break after using too hard or too long. You monitored only current during use to see 4+ amps, try monitoring voltage when drawing that much current. I predict the voltage lowers substantially, and that means you need a better psu to do some meaningful 2 ohm tests! Also, the added powered sub may thump when the head unit is powered with other equipment in many circumstances, not just this. The general fix was delayed power cycles.
10:22 damn it seems like "OCP: 4A" below to "home usage" logo !!! Already you consumed 4A in dyno test... I think 2000 mAh output is standard or not cliping current ?
Curious why they wired the tweeter's hot lead (red wire) to the cap and then to the resistor and then into the tweeter. It is like they are filtering before resisting...might be necessary to keep the resistor cooler. They do get hot (trust me).
Hi, I am trying to help my niece hook these speakers up to her turntable. I have the turntable going into an Amp, which I have plugged the speakers into ,using speaker wire to the spring loaded clips on both the speakers and the Amp. Only one of the speakers (the one that is not powered via the power outlet cord. It works if I use Bluetooth. Any help would be appreciated. Thanks
@@Mr.Robert1 If sounds deeper and louder. I basically went with it because the box size recommended looked to be about the same as the volume on the Polk sub. Also low powered powered IX is rated at 200Watts. Big D did a test on the Polk amp and is put out 86 watts Dynamic. Turns out it works. Have to watch volume and it does hit the covers a little if pushed in all the way. But I have receiver at -10 and the sub level at about half way.
How is the tweeter working with a cap set up like that? Also, was the speaker and tweeter plugged into the amp to measure the resistance? If it was, you measured the resistance of the speaker from the tweeter.
Yes, he measured the tweeter incorrectly. He measured from the wrong side of the cap and read through the sub through the amp connection. The tweeter does say 8 ohms on it and they're wired in parallel.
Which of the power supply's specs can I goose a little bit without immediately damaging the electronics -- is it the voltage or the amperage that will tolerate being bumped up a bit?
Name brand for the same price as god-knows-what. In 6 months from now when these speakers have a meltdown you can either rebuild them or throw them in the trash. However for the same money you have a name brand that research and development was probably a big part at one point before it became mass-produced. I have become fan the name brands live and learn.
@@Mr.Robert1 I have had my edifiers for 3 years and not a single problem I have had several there products and that is the brand name. They been around for awhile.
Although I am in a group home and want to move out of state to live in my new house it's worth 250,000 $ and I found on Zillow I want a powerful sound setup
***PLEASE CONFIRM*** Could be wrong but I think it will play and turn on without remote by clicking on the device from your Bluetooth settings on phone. My home audio amplifier works this way. As long as the device has power and you have previously connected, you should be able turn it on and connect. The standby mode, which just means plugged in and not using, should allow for the acceptance of Bluetooth signals 24/7 since it doesn’t take much power to run that Bluetooth receiver unit.
It doesn’t show up as a device until powered up. Now I didn’t verify it would stay in idle mode for an extended duration, if so, that would be the way to go
@@wal thank you for the feedback. Quite fast I might add 👊🏼 It would make all the difference in the world if it did work that way. However, i know the remote would cause me problems at some point. Unfortunate such a simple oversight like that will cause many to not buy.
Get a cheap universal learning remote as a backup, I’m sure you can find them super cheap online somewhere or if you or anyone you know has dish network their 20 series (20.x, 21.x) have learning and an aux mode.
@@wal hmm never heard of that before.... IR is IR and as long as the learning remote can "see" the signal from the original remote all it's doing is repeating a specific IR frequency.
I have a home theater system "black web" that claims it's pushing 1000w to the subwoofer, recently I took it apart and checked it out, it's got a small 6 inch sub in it I don't know if it's really putting 1000w to it I'd love for you to take a look if that's possible?
There's no way... Too small of a speaker to handle that power. I have a 6" JL sub and it can't even handle 1/4 of that. Does it have a power brick? If it does you can do the math. If not I'd guess 50w or less. It may be re using computer subwoofer style components.
@@volvo09 I personally didn't think so either. Just know if there's anyone to get the job done it's here lol. I'll check now, it does plug into external power. I wanted to replace the existing woofer with a nicer one if it's putting out the power.
@@volvo09 Unless maybe they are talking about the receiver itself... hmm :/ I've had it for like 2 or 3 years it's nice.. Sounds great.. Doesn't really have any lows lol
I don’t think this is well known since I’ve had people comment on previous vids it’s not possible for me to get more wattage output than the power supply is rated
@@wal They are not rated like amps. Most PSUs can draw a lot more than rated, but with consequences over time. Heat mitigation is the determining factor for it's longevity.
What’s up big d! So I just bought a nice old school Rockford fosgate Rockford Fosgate RBP2122 bandpass box with the original 12 inch he2 subwoofers in it. Still looks and sounds good! But I my self have never seen or heard of this set up….. I was hoping you would know something about it….. it looks like a one year run but I am not sure 🤔 . Might sell it but would like to know more about it so I can make my decision! I also received a Rockford fosgate 551s in the deal!

I would be interested in seeing what temperature the wall wart get to after being used at higher output levels... Not sure if it has an actual transformer inside which you can tell by it's weight or it's a SMPS type? Who knows?
But I would definitely like to see the output power with a 24V power supply! I bet that it would get pretty loud! Those 4" woofers are going to bump hard!
Great feedback, thanks
@10:11 - I probably would have wrapped that small wire around the amp clamp twice (or more) and divided the results by the number of turns. Also, I would like to know the output voltage of the power supply under load as a static voltage and a loaded voltage aren't likely to be the same on a cheese power supply.. Back to the video.
It is what it is, Ohm’s Law doesn’t lie, and it produced rated power.
Now will it do better with a more robust power supply? Sure, odds are much better dynamic. Might even eliminate the turn off and on thump..
Really like how you got to brass tax on these, great video D this was fun to watch. Neat speakers..
Thanks for watching and commenting!
Didn't know Dr. Phil was an audiophile type!😂

@@wal lolol. Good one!😁
Your videos are awesome bro you safe a lot of time going and looking on line to only guess if it's a good deal. I always check and see if you tested any amps I'm about to buy and if it's what I want thanks for your videos man!!!!
Awesome, thank you for the feedback!
Power on the subwoofer AFTER the left/right speakers to eliminate turn-on thump
But are you going to do that every time you turn on the system?
Parallel diodes across the subwoofer output hot and ground. Spec the diodes to bypass the thump voltage figure.
That or a timed relay on the signal output.
Even brands like Yamaha these days rating their powered studio monitors at 1000w even though the input powe is 90w max and so about 50w from a class d amp. Just saw two of them in a stage. The main speakers were powered by 3x 7200w class h amps 💀 the bass drop was pulling volt meter like vu meter.. at near clipping the mains voltage dropped to 200v from 245v.. 💀
Great Speaker system and Team should be proud about the Editing HDR output.✌️👌🇮🇳👍🤟🙏❤️🎧🤟👍🙏🙏🙏 Thank You for the information and upload.
Big D I love how you went threw and checked it using ohms law 🔥🔥🔥🔥🔥 another great job and well done video with the breakdown of these bookshelve speakers 👍👍👍
Thanks for watching and commenting!
Hey Big D, you measured the resistance of the tweeter incorrectly. 😉 You were on the wrong side of the cap and measured the sub resistance through the parallel amp connection.
Sho did 🤦♂️
More than a hundred percent efficiency? This must be those new class X amps that Elon Musk was talking about. The thing is so damn efficient, it gets cold when you run it.
Ha! There is an answer and it’s in the video
9:58 wooowi wasn't really expecting that!! 💥
That last beat was 🔥I need that
RUclips Audio Library
Let the theory of gravity do the work
You said it homie!
Looks like a decent little desktop set up, but that turn on pop is no bueno…
Yeah total bummer!
Thats exactly what I was thinking.
I'm only 6:30 into the video, but the "Tesa" tape on the wires was surprising and is a nice touch.
😝👍
12:02 that module is tpa3116d2
it's magic my soundbar also has a 36w (20v 1.8a) power supply it's rated 20w times 2 and 50 watts for the subwoofer output that's RMS power btw and it actually outputs it's rated power from that power supply i don't know how but it does somehow one interesting thing is that it has a very similar remote as thease speakers you reviewed and both have a 36w power supply
edit: oh alright it makes sense now still kinda crazy though ngl how underrated the current is for those who are wondering i did test my power supply and got 20.2v but i haven't tested it for current (yet)
That would be interesting to know. I see other brands with power supplies like this rated 20x2 RMS which is still well beyond the 36W power supply capability
Cool speakers. That’s a beautiful classic Kicker sub at the end. I loved those when I was in high school. Thanks Big D
Thanks for watching and commenting!
It might not give the thump turn on and off with all subwoofers. It all depends on the auto sense circuit and the timer.
With the Polk sub, I would try an in line filter ( ground loop isolator ) on the RCA’s. It may or may not eliminate the issue, but worth a try.
The power supply might be the cause of the off/on thump too. A more robust one might eliminate it. Regardless one of these ideas mentioned should eliminate it
Since you like to get in to more than car amplifiers , I would really like a review on “the epicenter “
Figured is might something you would enjoy 😊
Thanks for the suggestion
@@Only-Memories-In-The-End thanks for the reply . I just haven’t seen a good video with demonstrating and some explaining for people who might not know about products like that . I think he does a Fantastic job explaining stuff the simple way that even a beginner would understand . Plus a beginner definitely does not know about the epicenter 😀
@@Only-Memories-In-The-End he is reading the comments . And I’m sure we will see something . This is way too good and way too confusing to not make a video out of it 😃
That was a nice detailed review. Thank you.
😎👍👍
A lot of times those cheap Chinese power supplies don't have any protection and can dynamically do double their power. I have one which can do 6 amps when it was rated for 1 amp. It'll burn itself up eventually but it can do it.
👌😬👍
Awesome video. That's 77.4 watts! Wonder if the fets would take 20 volts at 4 amps? Thanks for going through the trouble of figuring out what we all were curious about. Cool little speaker's
Apparently the chip can handle 24V, just not sure about the rest of the board
@@wal Those Capacitors store energy also and regulate the current pikes. That helps the power supply a littlebit.
@@villekinnunen6357 that is true but since they are quite small they probably won't do that much.
Running 24v 6a on my SMSL amp, and it does a decent job with my 8 ohm bookshelf speakers.
Sound quality lacks quite a bit without a toroidal transformer feeding clean power though.
@D S I'm designing some bookshelfs finally. Been wanting to do it for a while. There are so many amp boards to choose from!
But do these speakers work bluetooth from a TV? Or do they need wired through the Digital Audio Output?
I'm not surprised the PSU is underrated. It is warranted to make _at least_ 2 amps at 18v, beyond that is extra. It may overheat & break after using too hard or too long.
You monitored only current during use to see 4+ amps, try monitoring voltage when drawing that much current. I predict the voltage lowers substantially, and that means you need a better psu to do some meaningful 2 ohm tests!
Also, the added powered sub may thump when the head unit is powered with other equipment in many circumstances, not just this. The general fix was delayed power cycles.
Assumptions all wrong, but I understand why you’d go there. Voltage didn’t drop and powered sub has no issues with other sources
10:22 damn it seems like "OCP: 4A" below to "home usage" logo !!! Already you consumed 4A in dyno test... I think 2000 mAh output is standard or not cliping current ?
Damn those laws of thermodynamics.
Nice video, Big D. Thanks for the great content!
Thanks for watching and commenting!
sir can you do a review of rcf active speaker and find their true rms watts?
Those are nice. Just add a power button. No big deal. Thanks for the vid.
Thanks for watching and commenting!
I had a Belva car amplifier which did a loud thump when turning off and on which was very annoying.
Curious why they wired the tweeter's hot lead (red wire) to the cap and then to the resistor and then into the tweeter. It is like they are filtering before resisting...might be necessary to keep the resistor cooler. They do get hot (trust me).
Great video. Love your channel my friend. Also extra thumbs up for uploading in 4K HDR.
seems well made and look good,like the fake wood effect.should come with a tube of glue for the port lol
Yes for sure
Hi, I am trying to help my niece hook these speakers up to her turntable. I have the turntable going into an Amp, which I have plugged the speakers into ,using speaker wire to the spring loaded clips on both the speakers and the Amp. Only one of the speakers (the one that is not powered via the power outlet cord. It works if I use Bluetooth. Any help would be appreciated. Thanks
More home sub content!! Have loved your videos for a long time!!
Thanks for watching and commenting!
Big D they saw you coming a mile away so they said we need to make rated
👌😬👍
Sweet video. I upgraded my polk subs with a Skar IX10 D2 for more bass. Would be great to see them on a 24v PSU.
Never knew that Skar was an upgrade from Polk Audio? Does it actually sound better now ?
@@Mr.Robert1 probably hits considerably lower but definitely not the same sound quality.
@@Mr.Robert1 If sounds deeper and louder. I basically went with it because the box size recommended looked to be about the same as the volume on the Polk sub. Also low powered powered IX is rated at 200Watts. Big D did a test on the Polk amp and is put out 86 watts Dynamic. Turns out it works. Have to watch volume and it does hit the covers a little if pushed in all the way. But I have receiver at -10 and the sub level at about half way.
Interesting 🤔
Do you think this could outbeat a soundbar just thought to ask out of a curiosity question.
Yes at similar price I believe so. Most of them have very small drivers, around 2-2.5”
@@wal if that's true then I would think this would be better than a sound bar.
Awesome video Big D!!! Love these videos!!!
The bass response (without sub) sounded pretty good on my setup.
Sounded fine in person too
How is the tweeter working with a cap set up like that?
Also, was the speaker and tweeter plugged into the amp to measure the resistance? If it was, you measured the resistance of the speaker from the tweeter.
it just filters out the mid and low frequencies.
Yes, he measured the tweeter incorrectly. He measured from the wrong side of the cap and read through the sub through the amp connection. The tweeter does say 8 ohms on it and they're wired in parallel.
So what is the correct power supply voltage/amperage should be used for this speakers?
Could have picked up some Edifier speakers, same price, presumably a better brand. No sub out thought
You should do a test with Jamo powered speakers 801 from crutchfield…..I enjoy them with watching movies
I'm thinking the way it's wired it would bring down the ohm load.
Which of the power supply's specs can I goose a little bit without immediately damaging the electronics -- is it the voltage or the amperage that will tolerate being bumped up a bit?
45Hz from a 4-inch driver? How reliable is that? (Btw, I grew up in Port Charlotte, Fla.)
I got a pair edifier bt1700 powered bookshelf speakers similar to those and wow they sound good for $120 I paid for them
Name brand for the same price as god-knows-what. In 6 months from now when these speakers have a meltdown you can either rebuild them or throw them in the trash. However for the same money you have a name brand that research and development was probably a big part at one point before it became mass-produced. I have become fan the name brands live and learn.
@@Mr.Robert1 I have had my edifiers for 3 years and not a single problem I have had several there products and that is the brand name. They been around for awhile.
Great feedback. I was originally planning on getting the new Amazon Basics powered speakers, but these looked more compelling for the $$
I'm curious about where they tuned the system to. Any dimensions (diameter, length) for the port?
Impressive.
Most impressive.
👌😬👍
How do I turn off hdr mode on Android?
Hey I'm looking for speakers for my new house in Florida I seen these speakers and maybe get them
Although I am in a group home and want to move out of state to live in my new house it's worth 250,000 $ and I found on Zillow I want a powerful sound setup
***PLEASE CONFIRM***
Could be wrong but I think it will play and turn on without remote by clicking on the device from your Bluetooth settings on phone. My home audio amplifier works this way. As long as the device has power and you have previously connected, you should be able turn it on and connect. The standby mode, which just means plugged in and not using, should allow for the acceptance of Bluetooth signals 24/7 since it doesn’t take much power to run that Bluetooth receiver unit.
It doesn’t show up as a device until powered up. Now I didn’t verify it would stay in idle mode for an extended duration, if so, that would be the way to go
@@wal thank you for the feedback. Quite fast I might add 👊🏼 It would make all the difference in the world if it did work that way. However, i know the remote would cause me problems at some point. Unfortunate such a simple oversight like that will cause many to not buy.
I have that same Polk Sub woofer.
It’s a good one for the $$
Very nice, they sound clean!
Yoooooooo cool vid ..,by any chance could you do a dyno of a kicker pxa 300.4
Can you try for tested twisted amp ?series f4 260?
Better than edifier 1700 bt ??
But what voltage did the supply dip to at 4 amps??
im a bit confused that the SMD was reading 14.48 while the supply was reading 18.2 4 volts is a huge difference
The Amp Dyno was powered using my LTO lithium bank, the amp used the 18V power supply
Do they power off after time of no sound? Can I use for pc speakers? Can just leave them on
Get a cheap universal learning remote as a backup, I’m sure you can find them super cheap online somewhere or if you or anyone you know has dish network their 20 series (20.x, 21.x) have learning and an aux mode.
It’s funny the instructions say learning remotes won’t work but I didn’t take the time to test. It is IR so should be able to be learned
@@wal hmm never heard of that before.... IR is IR and as long as the learning remote can "see" the signal from the original remote all it's doing is repeating a specific IR frequency.
I have a home theater system "black web" that claims it's pushing 1000w to the subwoofer, recently I took it apart and checked it out, it's got a small 6 inch sub in it I don't know if it's really putting 1000w to it I'd love for you to take a look if that's possible?
There's no way...
Too small of a speaker to handle that power.
I have a 6" JL sub and it can't even handle 1/4 of that.
Does it have a power brick? If it does you can do the math. If not I'd guess 50w or less. It may be re using computer subwoofer style components.
@@volvo09 I personally didn't think so either. Just know if there's anyone to get the job done it's here lol. I'll check now, it does plug into external power. I wanted to replace the existing woofer with a nicer one if it's putting out the power.
@@volvo09 You are correct it says 48w :o
@@volvo09 Unless maybe they are talking about the receiver itself... hmm :/ I've had it for like 2 or 3 years it's nice.. Sounds great.. Doesn't really have any lows lol
I think I would have tried it with a more capable power supply, I think it was running out of juice before that amp chip was.
Most of the power packs can easily be over drawn. The current rating is based on median loading. The voltage should stay fairly stable.
I don’t think this is well known since I’ve had people comment on previous vids it’s not possible for me to get more wattage output than the power supply is rated
@@wal They are not rated like amps. Most PSUs can draw a lot more than rated, but with consequences over time. Heat mitigation is the determining factor for it's longevity.
What’s up big d! So I just bought a nice old school Rockford fosgate Rockford Fosgate RBP2122 bandpass box with the original 12 inch he2 subwoofers in it. Still looks and sounds good! But I my self have never seen or heard of this set up….. I was hoping you would know something about it….. it looks like a one year run but I am not sure 🤔 . Might sell it but would like to know more about it so I can make my decision! I also received a Rockford fosgate 551s in the deal!
I believe from 2002/3 timeframe
They’re nice looking , and nice review
👌😬👍
Well that's pretty cool.

Can you do a review of the Recoil REA600-4
Will look into it, thanks for the suggestion
I am confused because there is the SaiYin DS6801, DS6801S and the DS6801k what is the difference?
DS6801 and DS6801K has same performance but DS680IK with MIC input and bass and treble adjustable. DS6801S is smaller in size than DS6801.
I wonder if you can use a higher wattage power supply on them? That would be pretty cool.
It may be possible
It's possible but then you have to balance other things on the circuit
