Hey DMS. Just a quick tip. You are not supposed to place the exciters in the center. To minimize bad harmonics you should place them at 2/3rd one direction and 3/5th the other. Or at least something like that. Parts express has a neat little doc about it.
@@46wireboy Dayton Audio has a web page on exciter speakers with all of the useful information on recommended materials and they do state 3/5ths in both directions.
According to Tech Ingredients one panel in dead center and the other panel 2/5 and 3/5. By having one panel of each they balance the different in frequency changes.
@@rongriggs4430 This is correct to my understanding. Each off these methods have different resonant peaks that cancel somewhat when two panels are used.
Nice. Tech Ingredients did a vid on this and it was the first i'd ever heard of it. it's pretty in depth so i mention it only because the guy (engineer) goes over some cool technical info, which you might find interesting with your refined versions. There is a particular ratio involving 2/3rds offset from each direction, I believe which turns out to impact his measurements a lot.
I saw a video on Tech Ingredients a while back where he tackled a similar project and since then I always wished for a reviewer to take a good look and find out if they can deliver on imaging and soundstage as well. How do these speakers need to be placed in a room? Love you channel, keep up the good work!
I'd like an in-depth video about how these exciteybois work and what criteria goes into making them good, and what mods and materials can be done to get different sounds and why. You put one on paper vs the foam, is that just for fun or to increase the range? Would mounting one to a piece of thin plywood, or some thin aluminum sheet, or having a sheet mounted on a frame of some kind vs hanging work better/worse? That's what would help our DIY minds. Right now I'm interested but now I have to go somewhere else to actually learn how to work these into my life. Edit: But yeah I'm all-in on seeing more of this type of content, hell yeah. And the intro was great. I wish there was just a little more meat in the hows and whys somewhere.
surf around a while theres plenty of experiments and studies on here, i have grabbed a few good 'rules' from 20 or so videos and looking and listening closely to be ready to make myself some.
What happened to the follow up on this? I scrolled through your videos and didn’t find it. I thought you did a nice job with the mics and the dsp. I would like more of this. Maybe a build with some refined looks.
I put an exciter on a piano,... Sounded like a real piano, any string instrument sounded really good. Hooked it to the outside, against the sound board facing towards the strings, I was mezmerized.
I wasn’t sure what you were using to create the driver, maybe a little bit of explanation would have cleared that up. I can’t believe you got that kind of sound quality out of those things!
Hi there What is the foam that you used? i would suggest you try polystyrene sheets could give a good quality sound effect or even a big cardboard box cut down to a 3 inch hollow. Since the speakers vibrate on a good surface i have seen that even if you nail the exciter material to the wall and keeping a gap of about 2 inches away they sound great. I have also tried to fix the speakers into an LED TV in place of the speakers the tv originally came with and it sounded good. Please try the same and let me know how it is cos my accoustics may not be upto the mark and you may have good ones. Thank you.
Love it. Looking forward to the A/B comps with your Magnapans. While you're at it, demo these against the studio monitors you have already in the same room.
I think you have the perfect space and equipment setup just for making some stripped to the bone comparison between those magnapan, the other B&W and whatever else you´ve happen to have in there... I have to ask... Do you think this is the death of speakers as we know it?
Since nobody’s can’t have any ideas of what sounds comes of this, since we only have the sounds that comes from the device your watching the video, to give a better ideas, it would be great if you could have played something from the speakers we see already installed on the ground, just tell exactly what they are , brands, power, basic info, and play those speakers and then switch to the panels, that would give most peoples a much better ideas of hearings both sounds, also maybe some more lively musics would be a good idea too !. This may reproduce a clean sound, but I’m sure that adding a subs is totally obligatory, because I can’t imagined any bass coming from theses, still it’s very intriguing and maybe if I could heard it live, I would take the jump and builts a few of those to install in the garage, I have a big garage that’s 3 sections, and already have an old Harmon kardon ampli/reciver of where I could split the sound from front to back, so I would need either 6 speakers or 12 would be even better, and since theses kinda are cheap costs, that’s why I would be interested, but if I have to buy 3 subs to go along, maybe it’s not worth it for me ?.
Try using the some of their other exciters like daex32ep-4, they sound better. also try some other materials. other vid shows some 2" thick foam but I have found that 3/8-.5" materials work best. Others already mention the driver placement too, I aim for the center of the spiral on a golden rectangle panel. Different types of foam and composites sound lightly different too.
My point is that you should include thicknes of membrane .It has own resonance frequency, which interfere with music ,aside of main dimentions as a main criterium .That is why the nature of membrane material is so important.
Excellent choice in taking the channel into the twilight zone :) Saw a Tech Ingredients thing like this before Christmas (in fact I think I pinged a link to Zeos) A very interesting concept and something I think I will try out myself since it hardly breaks the bank. Experimenting with the panel and the driving amp for a sound that meets your own ears is the key - and there goes another outlet for reviews. Keep evolving.
Wow, the transparency was definitely a surprise. Would be great to see some diy methods for room correction maybe using equalizerAPO or something similar.
Would greatly improve performance if you move those towards a corner. I believe the theory is to generate modal excitation of the panel. As opposed to linear piston motion of conventional speakers. So it’s the complete opposite of normal speaker building where you want ZERO resonance modes, which causes destructive interference. This design exploits that resonant interference in a constructive manner. Just a thought my friend, Try foam core or types of balsa sheet or similar. Also, the bigger, the better! It will increase BOTH Low frequency & highs due to added surface area and modulating mass/dampening etc. Cheers!
Try moving the drivers on each panel 3/5s of the way down and 3/5s of the way from one side. Don't ask me why because it's hard to explain but it makes a big difference in the sound
Quite cool. Seen something simular b4 but they moved the driver off centre to adjust frequency. What were you thoughts on the sound over all? Regarding the t-shirts. I know this is to raise money for you and the channel but if you had given a voucher to patreon members for a dollar or two that would have been a cool move (giving back a little). Obviously I don't know what your margins are but just a thought. Loving the variation in content and still donating. Keep going mate.
you do a good job making youtube vids...would like to see a vid on how to make a vid...maybe a 4 part series or something covering all the bases. good luck with the real world and youtube.
Your mistake is that making them centered as possible will create resonance of certain frequencies. Thanks for the video, pretty good and easy to make such speakers.
Interesting that you had absolutely no opinion as to the sound that resulted from this experiment. How, for example, did they compare to the B&W's - even it's just a rough opinion based on memory or experience with commercially available speakers. Are they even close? In the same ball-park? - on this end we are limited but what we are watching/listening to them through.
euhm, you wanted to put it as centered as possible, but actually you shouldnt search around on youtube and the net, you should place it 2/5th 3/5th....
IMHO, the more effort and money you put into exciters, the less it becomes worthwhile. You just won’t get good dynamics. It sounds clear but without much excitement. Exciters are only worth it if you already have an amp and spend $50 max on the board and the means to hang your speaker. The simple fact is that you can get a good pair of bookshelf speakers for a little over $100 so why bother!?
If you're interested in the ways that materials will impact the sound, check out this guy: ruclips.net/video/CKIye4RZ-5k/видео.html His videos are VERY informative.
You made them wrong though. This is what happens when people make shit that they don't fully understand. Go watch the original video on these speakers.
This is definitely an awesome direction to be taking this channel, I want to see more and more of this
Yup! this was different! I like it!
Not long hours. I have a full time job and dedicating entire weekends to DIY wouldn't be my personal idea of fun

Can I paint the foam board?????

I put an exciter on a piano,... Sounded like a real piano, any string instrument sounded really good. Hooked it to the outside, against the sound board facing towards the strings, I was mezmerized.
Seems like it already was a real piano by the description.
I wonder could they be hooked to a digi piano to enhance the acoustic sound.

Good form in opening the box, you cut away from yourself! Enjoyed the video, keep it up.
Love it. Looking forward to the A/B comps with your Magnapans. While you're at it, demo these against the studio monitors you have already in the same room.
There is a video of this where they experiment with different boards and exciter position
About 2/3 and 2/3 was what they found for best response.
ruclips.net/video/CKIye4RZ-5k/видео.html
@@daniel46245 2/5 3/5 if I remember right. Good video.
Nice! Have to see if there is something like this obtainable here in germany. What was the name of the song?
DMS, have you ever tried diy modding KSC75's?
The exciters work best when there off center or else you start getting resonance
What brand of EQ are you using again?
Does anayone know where to order these parts but in EU?
I have the magnepans and I absolutley love them.
WOW these sound GREAT!
I think you have the perfect space and equipment setup just for making some stripped to the bone comparison between those magnapan, the other B&W and whatever else you´ve happen to have in there... I have to ask... Do you think this is the death of speakers as we know it?
Very cool! I'm curious about the B&W's you have, tho. What model is that?
they're the DM7. I love them but I actually sold them for support more DIY projects.
Nice work

It would've been nice to measure this speaker's frequency response and show it to us.
Okay, I'm 100% a headphone guy but now I am tempted try this DIY speaker thing out.
This is an immersive listening experience, the complete opposite of using headphones.
I like this DIY content, great addition to the channel.

How was the sound of these exciters compared to your other speakers?
Not quite as good as my other speakers, but still great with EQ and my other speakers are MUCH more expensive.
@@DMS3TV Just a suggestion, when doing DIY a quick review of the results would be nice.
Very nice, man! Keep it up!

so. what the hell was your opinion on the sound
Nice video. But you'll get a better results if you DON'T mount them dead center on your material (also extruded polystyrene works better)

Use many small speakers to make into a large speaker.
So what are they worth? If you were paying for them are they 100 speakers?
If you’re willing to put some time into EQ yes they are more than worth it
Wow. They sound incredible on my mono tv speaker lol. Seriously, why not give your opinion or a review of some sort?
Your mistake is that making them centered as possible will create resonance of certain frequencies. Thanks for the video, pretty good and easy to make such speakers.

Foam core is real shit to cut. I used a sheet to make a screen for my projector and the edges look like ass.
3/5 ratio prevents damping second speaker should be that way

Worlds best speakers? LOL
You showed us the DIY you were there in person you know music you know speakers you didn't tell us how YOU felt they faired up
Ci hai provato, bravo! Peccato che hai sbagliato decidendo di mettere l'exciter al centro del pannello... Riprovaci...
Wow
He could at least thank Tech Ingredients channel for the idea...

You made them wrong though. This is what happens when people make shit that they don't fully understand. Go watch the original video on these speakers.
I made a part 2 correcting myself and updating but youtube removed it. This was my first video with exciters (several years ago)
No comments on how they sound... Just a 30 second sound clip... If you are looking to build a project with these exciters best look elsewhere.
