Ciao, bel video, secondo te si possono installare più pannelli ? magari 4 invece di due ? ecc. ecc. un saluto Fabio
I really wanna see DMLs made with different exciters!
Kia Ora & Good Evening from Unsworth Heights, North Shore, Auckland, New Zealand …Great Video Bro …
Listening on my Chinese Bluetooth 50x2 amp paired with my Realistic Minimus 7. It's alright. Good for the price.
Good job guys!
What does DML mean?
DML stands for Distributed Mode Loudspeaker.
@@alexmendiola Thanks. Did not know that.
I enjoyed the style of video presentation. Lumber selection issue understood. Chris also provided a plywood version. GooD job!
I don’t know what was the purpose of this video but it’s got to be one of the most uninformative videos I’ve watched
Fair enough. Thanks for your feedback.
Box sounds marginally better because the enclosure is bigger so lower frequencies are reproduced better. I would love to hear this sub in a ported enclosure
i just saw the bigger high efficiency exciters with 40W. I think, i might try them out. i have to check the coating from tech ingredient channel. is your version with the epoxy glue giving it extra stiffness to create a stiff membrane instead of something wobbely?
Great question! I did a fair amount of research on this idea. Tech Ingredients suggested a 1:1 mix of white glue and water. In this build, I followed that recipe with the addition of India Ink to tint them. In a more recent build, I used RustOleum Appliance Epoxy. In my research, I found that the more rigid the surface layer is, the more accurate the production of the sound. To my ear, this holds true. I still want to get a diagnostic microphone and do more empirical testing. Hope this helps. :) P.S. this a link to the product I used: www.amazon.com/Rustoleum-241168-Quart-White-Appliance/dp/B0067NM12E?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=ATVPDKIKX0DER
@@RolandWartenberg I am so glad to hear that!!! I still get chills listening to my set of DMLs as well. Maybe you and your daughter could make some together.
From the original video, this one and a couple others, I start considering the hipotesys of using 3 different layers of coating: a more rigid one, at the bottom, for the low freqs, a medium one at the middle and a light one at the top, for high freqs (maybe concentric circles would work better, with high freqs at the edge of the panels?).
Well, I'm no expert in acoustics but my suggestion if you do try concentric rings is, it should be high frequencies at the center and low frequencies at the ends. Low frequencies need larger lengths to be accurately represented. The reason is that lower frequencies have larger wavelengths and you require a larger length panel to produce lower frequencies. The length limitation is why most DML speakers have aggressive bass roll off.
Testing for 1 minute with speakers plaing back?
When Radio Shack was getting rid of the ash trays in the stores, we took them an threw in some 8" woofers. They made some nice homemade bazookas for a car trunk !
Would these work plugged into home theatre amp?
Yes! I just set up a 7.1 Atmos surround sound system for a home theatre and they work great! You will need a traditional subwoofer though. They don't have enough low end for home theatre.
@@alexmendiola so good, and thanks for responding to a 2 year old vid. Saw in the other comments you were doing ceiling mounted parallel to the floor and I was thinking of doing the same. Is this what you ended up doing?
I'll take some pics. I should totally do another video. I'm setting up the screen this weekend. I made some frames in which the speakers hang and the ceiling speakers are hung at an angle where the wall meets the ceiling. I use a needle with waxed thread to keep it from swinging down.
@@alexmendiola sounds good, would love to see new vid 👌
So what did sealing these panels do for the sound? I've seen other people test painting them directly, but the best sound was always with nothing put on the surface. I want to make some of these myself, and if the sealant works well, I might look into doing that too
Hi Jeconiah, That is a great question! I have not done any A-B testing between sealed vs unsealed panels. I simply trusted the testing done by Tech Ingredients. Check out his video for more information (lot's of technical detail in there!) . ua-cam.com/video/CKIye4RZ-5k/v-deo.html When I have the money to purchase the necessary testing equipment, I will absolutely validate the difference between the two.
I see this is 3 years old, so don't know if the comments are monitored any longer. I would like to use this in my old classic car, 12 volt negative ground system. I have a 6"x9" speaker in the rear deck and a 7" speaker in front. I would appreciate some feedback if you think this will work for me and what speakers you'd recommend. I won't be hooked to the old radio at all, just using Bluetooth or aux. Thank you.
Hiya Butch! I don't think this amp would work too well. Most car audio speakers require way more power than this little amp could muster. However, if you can find full range drivers that only need about 35w that fit in your classic car then it will work just fine. The speakers I used were small desktop speakers for home use. You could try using home audio speakers in custom enclosures. Speaker design is a pretty deep rabbit hole. But, it's totally subjective. So if you pick a couple drivers from partsexpress.com that have the right power needs and they fit in your car and they sound good to you, then go for it! Please hit me up with additional questions if you decide to try that route.
I have mine hanging about two inches infront of a wooden wall and they sound great. They sound great but a bit bright and wierdly muffled. It might be that I am using a very cheap and cheerful Blue tootth to DAC. Am am planning on building one that is a bit better.
I totally agree with you Mark. They do mellow after a bit of listening, but I absolutely want to get a decent DSP to even out the highs. My next project is a 7.1 Atmos setup. Fingers crossed it works well. I may even make another video :)
What is the point of sanding the boards to remove the sheen only to add it back thicker with multiple layers of paint.
Check out the Tech Ingredients video on this for the technical details, but it tones down the highs a bit and evens out the frequency response. I def recommend using these with a traditional subwoofer and DSP of some kind. My next project is a 7.1 Dolby Atmos setup using DMLs as my Center, Left, Right, and surrounds with an 8" sub. I'm hoping the AV Receiver will balance out the frequencies. If not, I'll add a separate DSP.
Been browsing all day since I came across the tech ingredients video just to convince myself to follow you...sound from yt isn't convincing so I might start looking for that magic little exciter, Philippine market isn't the place to have those.. fo now👍
I'm so glad you're convinced to try these! I'm in the process of building 7 small DML panels to try it for a Dolby Atmos Home Theatre project. Maybe I'll finally do another video of that. :)

Good men "teach" young men.
Think this would be a good choice to run 2 6in P16 speakers in a custom enclosure for a motorcycle?
Awesome
Have you considered that the paint could change the xps vibrations?
That's the point I think.
I'm in the middle of making these myself. Just made a stop to Home Depot to grab the boards and epoxy. I've never soldered before; in fact this will be my first project on anything that uses electricity. Any tips? Any way to do this without buying an entire setup to solder?
Great question! You could use crimp connectors. You can pick up some inexpensive sets from Amazon.

keep your eye on polarity of cables on exciters, if you connect it on some battery, the exciter needs to go out, if its going inside, you need to change polarity on it
I first came across your review on Amazon -- the first 10 times I was trying to decipher each word to look up the song your playing -- I had somehow skipped over the part that you said to check out the description- after trying to make Amazon to allow me to message you (if they would do it 😂😂) and ask for the song ….. I went back again and heard it so I figured you had done a UA-cam review as well-- lucky for me, once I got on UA-cam … it only took a couple seconds to find ! Thank you for sharing ! & killer review -- I just ordered one for some outside speakers I’ll be trying to put up…. I have never wired speakers before so wish me luck lol
I'm so glad the video was helpful to you! It's a great little amp. Good luck on the build!
Alex, admire your empathy, patience, observation and assisting younger ones to become more open, more sociable, more confident, capable to express themselves. It was a pleasure watching you guys. I hope every man will be a little bit like you and will become a good father to own kids. World will be brighter, nicer, safer with happier people around. Thanks!
Not that I needed to know how, but after watching this, I'm surprised how few people even show the step of dealing with the wires in their videos about making DML speakers.
Could someone test a taller panel for more bass? 24 x 48 or even taller.
4 minutes?
Question: Why did you decide on "painting" the panels with glue/water/ink? I'm guessing you didn't test the performance of the speakers prior to painting them so you can see if your "paint" had any negative effect.
the youngest seems stoned 😂
lol just try to find that foamboard in the UK and then try to buy a single sheet! you have a much better chance of finding Rockinghorse shit as the UK is absolutely retarded and greedy as far as sales practices go you have to buy a whole pack of full size sheets as most outlets are on line and those who have physical outlets don't seem to stock that shit!
Thanks for the video. I used this board in a recent (very strange) project and got great results. I tested the board for output power as well. Video link if anyone’s interested: ua-cam.com/video/JPrklV3l5yw/v-deo.html
I am glad you mentioned tech ingredients he is awsome
Right?!
@@alexmendiola I liked your bull too keep it up
You could mount the brack undernead the table, no need to fold
Awww, the way the boy's face lit up when he heard the bass.
Can these speakers be hooked up to the back of a regular stereo?
Sure! The exciters are rated for 24W @ 4ohms so make sure you have an appropriate amplifier.
I cringed when he Added glue, ink, and water. I was like NOOOOO its ruined!!!!
I never noticed Tech Ingredients cover their panels in a mixture of glue, water and ink. So, my questions are: 1. Why these three ingredients together? 2. In what proportions? 3. Why not just paint them?
Hey Karl, Here are the answers I have: 1. The idea I think is to create a thin hard layer to all surfaces in order to improve frequency response. White Glue is cheap, water is free, and the ink was just to give them a different look than the pink of the foam. On a more recent build, I used white appliance epoxy and they sound even better than these. 2. For the water/glue mix it's 1:1, I just eyeballed the color with the ink. 3. From my research paint is too elastic. You want something that will harden.
Felt a bit of cringe at 2:44. 😬
Was thinking about making these but painting the panels instead. Think that would seal it enough?
I suggest watching this video it will answer your question: ua-cam.com/video/XC814uQjlaE/v-deo.html
No bass no mids no thanks sound like crap
Yea, the exciters may be less than 10 bucks, . . . . . but the amplifier is $78 !
Why sand the foam? Is it to provide a rough surface for the Ink/Glue coating?
In the Tech Ingredients vid they say that there is a thin film of plastic on the outer layer. Removing this by sanding allows for more vibration. Or something like that. Painting it is completely optional. There's another bit of advice depending on what paint you use. I think spray paint would be better than brushing anything on. I thought it was weird seeing that in this video - since they went through the trouble of sanding it. The thing is - with spray paint, it's a good idea to hold it a certain distance away so the acetone in the spray paint doesn't melt the foam and evaporates before it... settles. And apparently, it takes a lot of paint doing it this way. :-/
@@Sutoraida1975 I intend on placing these speakers under our pergola. Pink won't cut it. I thought about painting an ivy or floral design on the front side so they will blend in with the rest of the plants.
There are water-based spray paints that are safe for polymers, if you can find them. Might make this a lot easier and less wasteful.
For the black coating, how about black gesso? Would that work too? (It's the primer artists put on canvas to prepare to paint. It can be made with acrylic, which is somewhat hard.)
Nice idea, but from what I can tell you want something that will be as hard as possible once it cures. Not sure how hard Gesso gets, but that would be a great experiment!
can you use the aux input and bluetooth interchangeably or do you need to unplug the aux input cable before using bluetooth?
Here's the same idea, only I used GUITARS instead of flat panels: ua-cam.com/video/cBgrLvp_bUM/v-deo.html
