What sort are you thinking about building? I keep toying with building either the flat panel speakers made out of foam-core board from Tech Ingredients on YouTube, or the big giant speakers he made. ▶ this video link edited: Thought DIY Perks did the big speakers, found them on Tech Ingredients.
Yeah was going to say, this reminded me of this[1] video (series of videos actually, but this is the first in the series). Interesting stuff. [1] ▶ this video
I kind of want to build one of these amps and connect it to a set of speaker built with these cheap exciters... One of the Youtube channels I follow messed around with them link but he got that from this other video ▶ this video where he goes into all sorts of experiments he ran on the exciters to find the right design.
A 40 Hz model is already down to $1000. We may be on the cusp of some kind of sea change here. How insanely light could an E-Ink flatscreen monitor get? You don't need a backlight, so the power requirements would be much smaller and that would be a huge advantage to making something light. I could imagine an updated version of a "Sunflower" iMac built using one. MacOS resembling a magazine seems to be what Steve Jobs envisioned and what Apple is aiming for right now. Could they be made in such a way as to resemble good sheet material for acoustic exciters? ▶ this video
