DIY diffuser

Hi there, I am working on my little 3.5 by 3.5m studio. I have done most of the absorbers and clouds. I am quite happy with the results but as I have left a flat wall I have a little resonance which at certain positions is really enoying. Since the numbers of absorbers are sufficient 3 walls out of six. I was thinking of diffusers. The wall is perfectly flat and that is what creates that nasty short resonance. When thinking about DIY solution to diffuse the sound on this wall, I came up the idea of putting fake wall stones of this type: My question is imple, is that a good idea ? Thanks in advance. Alex

I like it...but how? there is drywall behind? how you did ?

Behind is a concrete wall covered with 70mm of drywall as block: The wall had been painted as I thought it would be finished as is. But then the stones will be put on it. So will the stones as diffusers work ? Alex

No. Atleast not like the pic you showed. For one the "cavities" (dunno what to call'm) are too shallow. That wall is just a plain 'ol reflecting wall. Flat as pizza. No diffusion goin' on there.

ok, so what would you suggest I do ? Alex

just to mention that a high frequencies diffuser would do in my case. Alex

I'd suggest to forget about a diffusor. Your room is too small to actually get the diffuser working. Better stick with absorbing panels.

yes, sure but then I will have a quite dumb room. Can't we have in a small room a nice acoustic ambiance ? Alex

Sure you can, I never said it couldn't. Do you know what a diffuser does and how to use? Small rooms very well need absorption. A diffuser won't make it really sound "bigger" if that's what ye after. That's the thing with small rooms... they sound small b'coz they ARE small. Nothing wrong with that tho.. Is your room a tracking or mixing space?

It's a tracking room. I have done all absorbers according the JS Wall units, + clouds on the same logic, I have 2 walls and the floor that are hard (not absorbing). The sound now that the absorbers have been done, is quite dumb, which is normal and good, since I have no more reverb, at least as less as I can have. So what else can I do now, to give it a like of reverb ?

The best approach in a small room like this is to record dry and add ambience and reverb electronically when mixing. --Ethan

ok then, I don't have much choice...
