poly diffusors

[Tonio]

Polycylindrical diffusors. Or diffusors in general for the mix room. Aren't they advantageous if you have at least 12' from mix position to rear wall?
Am I mis understanding or can diffusors be used in smaller rooms? I had a poly (4'x6) on the ceiling towards the rear and it smeared the mids.

on another note, does it matter where you put diffusors? seems to be alot voodoo with diffusors.

Nada? nothing ? zip? got be be someone with Difussor knowledge here.

Please. throw be a bone.

My undertstanding is that diffusion is really not very effective in smaller rooms. Typically you find diffusors mounted on the rear wall.

Sorry, but that's about the extent of what I know. Did you review the acoustics section of the SAE website or any of Ethan Winer's articles? There should be some useful information in both of these sites.

Good luck,

I have polys on the side walls of my live room, which is 14' wide. Polys aren't really diffusors per say, so it's important that you know what you're using them for. For my purpose (eliminated flutter echoes/slap-back without deadening) they work perfectly. I didn't notice any smeared mids, but then again this isn't a control room. Mine are smaller (2'x6') and are bent along the horizontal rather than vertical axis, but I generally put them in opposing clusters of three on my walls. Allow the surface to vibrate and stuff some insulation behind them, and they double as high-bass traps - though not as effective as the real thing of course.

I got one running the length of the trusses on my cathedral ceiling, to prevent the ceiling/floor parallelism.

Thanks for the ideas guys. My goal is to tame the flutter echoes on the side walls-adjacent to mix position. There isn't much , but am getting the "ghost center" intermitently going in/out-left/right by moving my head about six inches either left or right.
Or am I going about this wrong. would diffusion just screw it up more? Maybe some panels there shoulddo the trick.

p.s. I do have bass traps, low-mid traps and absorbers on front rear and ceiling-nothing on the side walls.
