Emile Posted June 13, 2018 Share Posted June 13, 2018 Found several youtube posts re flat panels ( styrofoam, balsa, wallboard, etc ) used with "exciter speakers." looks like a fun project to try for less than $100 ... plus (if it works) might be good for surround speakers when "depth" is a problem. No clue about the sound though. Anyone experimented with these? 1 Quote Link to comment Share on other sites More sharing options...

YK Thom Posted June 13, 2018 Share Posted June 13, 2018 Fantastic! Funny enough I came across a guy at a trade show I was doing a few years ago who was selling something similar but less sophisticated. A small exciter type unit for about $40 Canadian that could be placed on just about anything and be used as a speaker. He was shooting for the camping backyard party market and tied to a cell phone or IPod type device. Sounded half decent on a pizza box, actually pretty good on an old school styrofoam beer/picnic cooler. For a century sound reproduction has been an evolution and refinement of very old tech, this may be the beginning of sound reproduction tech in the 21 century. 1 Quote Link to comment Share on other sites More sharing options...
twk123 Posted June 13, 2018 Share Posted June 13, 2018 I looked into these quite a bit a while back but never pulled the trigger on getting the components. From what I read they will make excellent surround or ceiling atmos speakers and they radiate in a way that nomatter what angle you listen you still get a good soundstage. Many people rum them with a super tweeter though for the high end. I think the optimal setup is using rigid fiberglass board. The technology is actually moving into the pro audio field as well: http://www.tectonicaudiolabs.com/ 2 Quote Link to comment Share on other sites More sharing options...
pzannucci Posted June 13, 2018 Share Posted June 13, 2018 Companies are selling hidden speakers this way. The speakers can be items you wouldn't typically think about like pictures on the wall or other items. 1 Quote Link to comment Share on other sites More sharing options...

Marvel Posted June 14, 2018 Share Posted June 14, 2018 I would love to hear a pair of the tectonic panels in a medium sized p.a. setup. I can see awesome possibilities. Bruce 2 Quote Link to comment Share on other sites More sharing options...

vondy Posted June 14, 2018 Share Posted June 14, 2018 The Honda Ridgeline "pickup truck" uses exciter speakers in the truck's bed panels so the entire bed is made into a tailgate speaker. 3 Quote Link to comment Share on other sites More sharing options...

Emile Posted June 14, 2018 Author Share Posted June 14, 2018 19 hours ago, YK Thom said: optimal panel Seems carbon fiber with a 1/8-1/4' honeycomb (w/ 1/8" cells) is the preferred material. Not much info from DIY's as this stuff is about $100 per square foot ... ouch especially since I believe 2x2' would be much better. OK; will order some tactile speakers from PartsExpress and "play" with cheap boards before I spend big money Cheers, Emile 1 Quote Link to comment Share on other sites More sharing options...

I don’t know, I listened to the video and it sounded pretty good. New tech and he was an engineer... once these are perfected they could spell the end of the electrostatic.

We've thought of pouring glue into it. 1 Quote Link to comment Share on other sites More sharing options...
Emile Posted June 19, 2018 Author Share Posted June 19, 2018 OK; ordered some exciters from PartsExpress and carbon fiber from another place ... picking up honeycomb panels from a local fiberglass shop (Haha ... did not want to screw around with cheap styrofoam panels ... what's another couple of dollars for a hi-fi nut ) Will post some results in the next couple of days.
