More Epic DML #4 - BMR Positioning
Just a quick update this time - I decided that it wasn't ideal having my HF drivers perched on top of the speaker, so I 3D printed a solution to get them a bit lower down onto the panel.
Not mentioned in this video (sorry) but I did also have to time-align them in the DSP, as the BMRs now sit a few cm in front of the panel. Luckily, the Hypex software makes this easy, as shown in my 'Basic Tuning' video!

My Bamboo Panel DML Speakers Sound Amazing!
A very elegant solution, and solid execution, instant sub. People somehow think these should do it all, rather than just a driver with frequency limitations. The 600hz 24db sealed makes me wish I had a DSP, and not a 20$ P.E. sale amp. Someone below mentioned AMT tweeters. I just installed a set of the car audio version, in my truck (does have DSP, active 4 way) They sound amazing, and have a dispersion that could nicely complement the way DMLs "fill" space. The pro4 even has a removable back, if you wanted to run dipole(!) Or sealed. Playing down to 800hz, all the options for frequency and rolloff. The idea for the exciter tweeter tho! Got me wanting to go look in my box of future projects, and see if I have any minis in there... Nicely done sir, look forward to where it goes from here! Edit: found some 13mm coins in the box, time to stick one to I dunno... Maybe a CD to start.
If you present these graphs, please show the noise floor as well. Since all measurements are only valid if the speaker noise is X db more than the noise floor. Thank you.

So my cast wax board suspicions were correct. The volume and clarity are leaps and bounds better than any polystyrene panel I’ve made so far. If you can’t find them online(if you do find them lmk where please) go to your local farmers market and see if they have any produce boxes they will part ways with. Thats all mine is. I cut the bottom of the box out. Used a bar of paraffin wax to fill in the now exposed the edge, along with any divots or weird spots along the surface, used a lighter to melt away the spot where I was going to mount the exciter put on several coats of super glue it out and let it dry and then put VHB tape on that and then attached the exciter, but I imagine you can probably just use epoxy
Wow interesting. I'll have to start playing around with this when I get the chance.
@@TypicalBenYT i wasn’t even actively looking for a new material but I picked the box up and was like wow this is super sturdy for being so light cut the bottom out and a 2 foot by 1 foot section weighs nothing but it sounds like an oak board when I knock on it.
@@TypicalBenYT 243-EX80S-8OHM look that up on mouser electronics. It was recently linked to me by someone that’s doing something similar to what you’re currently doing. They said it’s the best sounding exciter they’ve tried thus far
@@TypicalBenYT that visaton brand is also on parts express. a few models anyways. not sure if its the same one i suggested
Thanks for this! Have you considered reversing the polarity of the subwoofer or chasing the phase at the crossover point?
So reversing the polarity would result in a 180° change in phase, but with the DSP I can control that more precisely via the delay on the panels. Unless I'm misunderstanding your idea.
I was curious what effect you would be looking for by taking those actions?
Interesting! I can’t remember where, It might have been the forums or the tectonic engineers spoke of acoustic centres on dml. Although DML is immune to many traditional ills, it has been suggested that the radiating area reduces with rising frequency, also the initial impulse in the signal helps spacial localisation and imaging. If that is the case for critical listening you may want to get the bmr as close the panel exciters as possible. Any difference maybe more noticeable if your crossover slopes are shallow. The space between sources for interference at 10k is effectively nothing, In traditional speakers you would expect an interference pattern, but in DML it most likely manifests as a loss of imaging or just perceiving separateness.
Interesting thanks for that! I might have to play around further to see what happens!
good progress . . the slap echo in that room seems horrendous . .
Great video, the bass or low mids seem a bit absent. It might be the little Hotone mini amp is a bit shrill. Not that your speaker sounds shrill and no ice picky highs, its treble biased but sounds smooth so that's a great start. You could try running your Fender SS amp through the test speaker if the amp has a phono jack socket to plugin the speaker, just plug in your new flat panel instead. The panel seems very small to reproduce lower frequencies. I wonder if a bigger 500 x 1200 mm bass panel with a bass exciter hung behind the existing one might fill in the sound? You'd need a simple crossover too. There is a flat guitar speaker recently gone on sale from Eminent (not Eminence, different company), it's not much larger than yours.
Thank you! I agree it could use a bit more 'grunt'. There's no phono out on the Fender but I might try just wiring the output to the panel instead of the speaker for the next attempt.
I... tentatively feel like we're working backwards. I thought the whole point of DMLs was that they could handle everything from 125hz up to 16khz or so in a natural fashion. The whole point of MY research on audio in general is to have as few driver types with as wide, accurate, and natural of a response range as possible. Trying to tune and aim 4+ driver types is kinda a non-starter to me. I'd rather focus on broadening usage and off-axis performance so there's less to faff about with with physical setup. (I'm also focusing on car audio, and all that stuff (packaging in general, I mean) is by default more difficult in a car, hence my aversion to it.)
Yeah I can see this point of view for sure. I suspect that the lack of very HF is a function of the panel material (the acrylic seems to be quite well damped internally) so the options would be to use a different material or supplement with another driver. I don’t mind the complexity overly much if it sounds good.
Garbage, even Bose is better...
Good video as always Ben, have you thought about adding wave guides to your tweeters ?, may help the tweeters dispersion even more.
Thank you! Yes I have. I wanted to start with the drivers 'bare' and then try a few different things regarding waveguides but right now I'm not sure what direction to take with these...
So I think I randomly stumbled upon what could be IN THEORY the fucking best material for dml panels ever… absurdly light and shockingly rigid. I plan on making one over the weekend and will try to remember to report back. Anyways look into wax dipped/coated corrugated fiber board. Not like pizza box cardboard but the double walled stuff. I haven’t looked for it online yet but fingers crossed someone has it incase it sounds good.. which I’m thinking it’s going to.
Not sure if something fibrous would be ideal. I would assume the foam board that does "the best" does so partially because it's porous, and the plexi/lexan does well because it's smooth/hard and consistent/homogenous. My terminology might be wrong, though.
@@Drunken_Hamster I would typically agree with you. However the panel I made yesterday out of a 3$ piece of canvas glued on to cardboard from dollar general sounds shockingly good. The outside is well coated and after cutting it it seems like the “tubes” inside are lined as well. I honestly thought it would be solid wax right through but it’s not. Because when I say rigid it sounds like I’m knocking on the side of a piano… like S O L I D. And that aspect plus I he tubes being hollow I feel like it’s going to allow the sound to resonate through the panel better. But who knows lol I just started making these a few months ago and I’m a highschool drop out that delivers antiques for a living lol I’m definitely not the authority on normal speakers let alone dml panels lol I appreciate the feedback back though!!
@@LikelyLagging I'm you but older and less successfully employed, so like. :shrug: It'd be cool if you could make a video or take some measurements like Ben, here.
@@Drunken_Hamster successfullyis definitely a word than could be used lol unfortunately covid and fuel prices have basically gutted a 35 year old business that my father created. We are pretty much the only people that do it professionally and it was not incredible money but certainly enough to live decently. But now with fuel costing so much no one wants to ship anything so I had to get a part time job cooking. And I may have lucked out for a while and was able to work my father (don’t recommend btw, our relationship outside of work is awful) but I’m 30, with zero credit, no bank account and just moved into my own place with my fiancé. All on top of keeping what was once a raging opiate addition locked away. I ain’t judging 🤘🏼 shit happens and this too shall pass. If it doesn’t then we can just crank our bad ass speakers to 11 and say fuck the world lol As far as video I could probably post something here or maybe on twitter @likelylagging. I don’t have a calibrated microphone to take measurements though. But it’s on my list right next to a DSP and a solid 2.1 blue tooth amp so I can stop moving my big ass 7.2 receiver around lol if any one could point me to a decent iOS audio measuring app I could def do that tho, or if there’s something free on windows 10 as I do have a pretty solid studio microphone. Still not calibrated but probably better than the iPhones
@@Drunken_Hamster my suspicions were correct. It’s by far the best sounding panel I’ve made so far.
Hi, from what I have seen of that tweeter it is not so good in the frequency range that you want to cover. Also it's open back and he is having his backwaves directly reflected on the plexy right behind. I don't think that is an ideal situation. As DML is essentially a dipolar I would instead go toward a better dipole planar driver on top of the frame to be consistent. (EDIT: FYI I am using a Radian LT2 with Waveguide but I had to cut the back myself)
Technically dipole, but with some bipolar behaviour (little to no destructive interference in DML mode). “Diffuse dipole” to use Tectonic’s terms. Even so the reflections may or may not be ideal
@@Butternose Has someone measured DML diffusion on & off axis front & back ? Hard to find any relevant. A flat pannel like would put nearly as much in front than in the back. Same for the Tektonic. Can't find the same type of measurements.
Have you considered covering your frame in flexible material then gluing the panels to the material. The material would act as a suspension mechanism, which would flex with the vibration. Potentially allow the mounting of multiple panels to the same material? Might look a lot more attractive also. Just a thought, although too be fair I've never built one of these. Just an observation after watching a few videos :)
first. I'm going to build those DML speakers if it's the last thing I do before I die

Youve got th best unfo on dml speakers I could find on youtube. I am loving your videos. I pesonally built a dml speaker foe my living room, and used a 2x4 pannel of foam progect board painted to match th walls. Whwn i first tested it, i hung it from the wall, and was dissapointed by thw sound. So, I moved it to the corner of the ceiling and the entryway, lile youve got on the top right hand side of your house in this video. Once their the speakers sounded great, but lacked bass(as expected, I suplemented with an external sub). Anyway point beig i would loke to see some expeiements with differnt shapes and sizes for an enclosed rear box for your speakers
Apologies for the typos, I am typing on a phone
Has anyone ever tried to make a slightly concave face of the panels? Something to replicate a cone for a traditional type speaker. It probably doesn't have to be very deep, but a gradual change in face depth across the panel.
Informative and practical! Good job!
What program did you use to add delay on the panels?
It's a feature of the Hypex Filter Design software.
The shirt got my like!
Have you tried a composite panel? Plastic core with very thin aluminum on both sides.
No I haven't tried it myself. I do think after I've finished messing around with this (and one that I'm doing in parallel that hasn't had a video yet) I'll start experimenting with other panel materials and I'm interested to try composites of some sort.
@@TypicalBenYT Do it! I have been using that material many years with multiple exciters. Works well. It's sitting freely on the bracket. No frames. And round corners.
I like the acrylic panel better. I just finished my first acrylic experiment. Still tweaking because I used really thin pieces of acrylic. It's actually vibrating too much. Im only using 4 watt 4ohm exciters, 2 on each panel to get 8 ohns. I didn't see anyone using acrylic until today. I'm completely new to this. It's very satisfying . Ever tweak is an improvement so far😊.
Sounds like there is some cancellations going on like comb filtering. Also I hear some static noise just when you stood up? This is my DML>czcams.com/video/00spcs18MeU/video.html
Beautiful build! Around 10:27 you mention the BMR & DML acting as dipole, which you commented on in the video. DML panels operate as bipole in that front/back radiation is in phase. There is a reduction in output to the side of DMLs because of a lack of output from the edges of the panels and not not due to cancelation. A BMR acting as DML in high frequencies experiences this, but as frequency lowers and pistonic action takes over, those frequecies are dipole. So, a BMR has a mechanical "crossover", if you will, where low and high frequencies use different mechanics to produce their sound. It's not too different from a driver with a whizzer cone. Keep the videos coming!
Thank you! And thanks for the clarification.
The Tectonic boys call it diffuse dipole, so I guess that means it’s a bit of both. From an engineering standpoint it can’t be bipolar, as it’s a single surface and at any single point on the panel a plus on one side is a minus on the other and visa-versa. However because the modal behaviour produces a diffuse wavefront in the air, they aren’t prone to destructive interference patterns you would expect from a traditional source making predominantly coherent wavefronts. The traditional terms are kind of inadequate to sum up DML, because you have to specify the level of analysis to avoid contradiction… that said diffuse dipole/pseudo bipole both kind of work.
You do know you can get rew to autogenerate the filters for you and import direct to minidsp.
Dome tweeters have great dispersion. They're a dome, after all.
They do not, mainly because of beam-forming due to comb-filtering as waves leave the surface of the dome. That's why some dome designs have a phase guide to help with dispersion.
Nope sorry. A dome tweeter has a physical size to work, combined with it’s pistonic mode of operation that dictates the off axis interference pattern at any given frequency. DML/BMR don’t suffer from off axis interference in the traditional sense.
Dude, your volume is all over the place in this video, mainly so low not audible... at least for me.
Oh man. Sorry about that. It sounds ok to me on my PC and on my phone.
@@TypicalBenYT you can try to record sound from your listening space. It will be much more audible for all
Can I ask what you guys are listening on? I listened again and it seems ok no matter what device I use but I'd like to improve it for others if possible.
@@TypicalBenYT FWIW, I don't hear any issues with the sound. Thanks for posting your experiences and things you've learned on your journey.
@@jisozaki great thank you.
Are the next tweeters gonna be Air Motion Transformers?
I've got a pair of planar magnetics with an open back ready to test once I've had some listening time with the BMRs, but I'm also interested in the AMT drivers they look really cool.
@@TypicalBenYThave you tried mounting the tweeters on stainless steel plate? You would only need a 300x300 mm square for each.
I wonder how it would work out using 2 of those on each panel. Maybe go with one on each top corner and you could put some sort of cover that goes across to make it look more uniform.
Also I think all of this is awesome!

Plywood as a resonant material is not the best idea. Example the cheapest guitars are plywood.
This is definitely not how you wire them together. Good idea but you cant run power thru a speaker. You have the positive from the first to the negative on the second then the negative on the second to the positive on the third. Then with 4 its even weirder with the ground not connected to anything but another speaker. Not sure how or why you did it this way but pretty sure you got this completely wrong and almost positive most of them wernt even working for your test.
Ben, Initially, I would like to commend you for your content and I particularly liked this build and the final result. I have a question for you if you are still monitoring this thread and inclined to respond. My Audio system consists of Denon 4311 9 channel audio visual receiver, Front speakers are JBL ND310ii (2 x 10 inch drivers, 4 inch Mid and a 1 inch titanium tweeter) Front surround and rear surrounds JBL TLX140 (single 10 inch woofer, 4 inch midrange and 1 inch titanium) 2 by JBL 10 inch subwoofers You may notice no centre speaker and 2 speaker channel not utilised as yet. My question is, I am thinking of using a DML panel speaker for a centre speaker now, and possibly 2 DML panel speakers to complete the 9.2 system in the near future. The plan is to use 4 x 40 watt Dayton Audio exciters and a JBL tweeter for the centre and possibly the same configuration for the front high speakers in the future. Could you possible advise whether the DML system is practical or even good for the centre and front high speakers. MY audio room is dedicated to music and is 4 x 6 meters with all the walls totally covered in 2 inch foam and that is also covered by a carpet. The only furniture in the room is a cabinet 2 meters long and 600 high for the audio components and a single arm chair centrally located for maximum surround sound. Very much Man Cave stuff. I am an Aged Pensioner and Australian expat living in Indonesia where the adivce is impossible to get. For that reason, any advice would be very much appreciated. Regards Tony Chilcott
Just keep having fun with it, please bye some cloths man.
Has anyone tried balsa wood? It is light and stiff. I am thinking of building a set for fun.
why so much noise?
Unfortunately, I can see your measurements are not valid from upper midrange to higher frequencies, please investigate.
Are you refer to the rising HF response?
Yes, rising HF response.
Great video!!
I recently discovered DML panels through Tech Ingredients channel because I had an idea I want to play around with... I was originally considering turning a couple of cheap used drum kits off Gumtree (using the skins of both bass drums and different size toms & snares as drivers) into a tall pair of DIY planar floorstanding speakers by using adhesive sheets of aluminium to cut the trace and stick to the back of the skin and mount the magnet array on the inside, close enough to the skin to vibrate it. Then use an external active crossover to distribute the different frequency ranges to each of the different width drum skin drivers (the smaller the drum, the higher the frequency). But this would've probably taken a %@$%-ton of power and multiple amps to work, I don't know. Then by pure algorithmic chance I was recommended videos on DML panels using these exciters. I'd seen the bass shaker type transducers used before in gaming sim-rig setups. They're generally cheap, low wattage and pretty good for output so I thought "Why not try these instead!?". What do you think? I realise it probably wouldn't compete with proper floorstanding speakers like Magnepans and a sub or 2, but could it potentially be tuned to sound good enough for rock and metal music? I don't listen all that critically. Especially to music like classical, quiet vocal-focused music or jazz. I'm no audiophile and I have mild tinnitus anyway.
Good job! :) By adding a high-Q bandpass peak to the bass at 20-something Hz, you basically converted the subs into ported subs for all acoustical intents and purposes. You get all the group delay and phase shift just as you would by adding a port, you just use wattage and excursion to do it in stead of a Helmholz resonoance :D (the added distortion comes for free) It would be really interesting to see the separate bass/panel responses too, not just the combined response. I very much suspect you have a phase issue between 2-300 Hz where the bass still will play pretty strong with a 2nd order electric xo. The peak-and-trough response here might either be phase mismatching, or it might be already in the panel response? I'd go to a third order for the bass slope, and then play around with the delay between 1-4 ms to get maximum integration addition. Remember that ALL phase misalignments require an increase in driver power for both adjacent drivers, increasing distortion for both. On a totally different matter, when I played around with DML's I used the common foamcore boards that seemingly everyone uses. One very interesting (IMO) that I tried was to add 45mm rockwool to the entire backside of the panel inside the frames. This converted the polar response from almost perfect dipole to something more like a semi-cardioid. Not surpising when you think about what happens when you dampen the rear wave of a dipole. That was the best I ever managed to make that panel sound in-room.
👍
Great job!
Love the work, and I have to say those look and sound amazing. I like the DIY groove. The kind of minimalistic design is very, very nice. You have inspired me. sir! I am going to start working on my system, I want to try all DML speakers for my Sony Dolby Atmos. Why not!?
Thanks so much! That's great I reckon they'll be really nice as surround speakers.
Good stuff! You've made some significant progress here, I'm real curious now to see which way you go for room treatment. I documented my entire room treatment ordeal from beginning to end with measurements every step of the way proving state of change. Check it out if ya like: czcams.com/video/2PTnZ7BU-X8/video.html I'm really not a fan of the common multi panel approach, and I don't love the large panels that I built either, but they are very effective. So I'm really curious to see what you come up with. Cheers 🍻
Thanks a lot! I’ll definitely take a look at your treatment vids.
I thought after looking at the use of multi exciters on other sites that a second exciter should be placed in the centre? Yet you went to the opposite side of the first one towards the edge, is there a reason for that, that the others have not seen?
I was going by the guide linked in my description. I've never seen any evidence that 2/5 and center on the same panel is the best way. I think in the 1st Tech Ingredients video he uses those positions but on separate panels.
I dig that whole eastern vibe you got going on that setup.
