What ethan means is, check his company's, realtraps, new diffusor, and copy it. Don't bother with the rest, haha. Even better, buy one off him, lol.Ethan Winer said:Nick,

That's not a very good design IMO.

To be effective over a usable frequency range diffusors need to be fairly deep. So if you plan to clone a commercial product, at least clone a good one.

bass frequencies have huge wavelengths, with 20Hz having a 17m wavelength, with the peak being 4 1/4m. To absorb or defuse effectively(perfectly) at low frequencies, the thinkness of the absorbent/diffussing(i think) material needs to be the size to this first peak, i believe. So if you wanna absorb 90-100% down to 20Hz, the thickness of the material must be around 4m, or a reasonably thick, and dense absorbant material must be spaced 4m from a reflective surface. I doubt anyone really needs to effect frequencies that low, maybe 80Hz and above. So for full absorbtion at 80Hz, you material 1m thick, or a gap of around 1m. This usually isn't possible in a home or project studio, so you can only really gain partial absorbtion. The best place is corners, where a 2' wide bass traps straddling the corner has a max depth of around 1', which can have brilliant absorbtion down to around 250Hz, and then it tales off the lower the frequency.Nick_Black said:realtraps is a good company (or so I've heard) but i didn't know they made diffusers. and his side dosn't give you enough specs to build off of. but it did mention that it doesn't scatter the bass frequencies.. why's that?
and thanks Ethan Winer for that HiFi site, thats (by the looks of it) is exsacly what i needed.
ps, those bass trap vid's are extremly helpful.
