How much space do you have between the diffusers and ceiling ? They look like a close fit.

Nice job on the fabrication.

emailtim,
You are correct about the space between the ceiling and the diffuser. There is about 0.75 inches of space. I had to set the bottom of the diffuser in first then walk it in, the carpet made sliding them a no-no. Thanks for your kind words.

Hi there,

Thanks for the plans. The panels look great. I have a quick question (for anyone): I'm in Germany and the dimensions of the wood at the Home Depot equivalent are a bit different. Will this difference, if within 10% or so, severely diminish the effectiveness or just change the frequencies it's affecting? Also, are there certain dimensions that are more important than others to preserve? Thanks again for the effort!

A.

Just completed my first set of diffusers. My intention was to eliminate slap echo i had between some parallel walls in my theater, the slap echo was between the center channel up front, it was causing a bit Of intelligibility issue with dialog, i couldnt understand, i could hear it but couldnt make out what they were saying......at low volume

That issue is gone ! Slap echo, GONE !!!!! Thank you for a well designed product

PS: I start my second set tonite expecting the same results :0)

Here is a little bit of Mini-Me and Where's Waldo. See if you can find the Depot-Diffuser serving double duty.

Putting my room back together so things are in a bit of a disarray. Broadband traps are not hung yet and will be recovered. May make AbFusers out of the broadband traps.

would 7/16" OSB be okay to use? Have some leftover from a dedicated theater room build, no biggie if not will buy the 11/32" if required.

These are going to be pretty stout regardless, but perhaps add a couple of 2x4 horizontal members, or diagonal, between the sheet goods as a reinforcement/webbing. Have fun and good luck!

There are 2 layers of plywood in this build. The thickness of the back piece should not be a problem acoustically as long as it is structurally sound. 3/32" more against a wall is not going to make any difference. The OP uses his as "room dividers" that are placed out into the room.

I doubt 3/32" deeper on the 2nd layer would make much difference either. The LeanFuser design is based from 10mm metric stock. The author of the LeanFuser has stated that substituting Imperial dimensioned lumber (1/2" or 12.5mm) yields slightly better results due to the increased depth than the shallower metric version.

Using OSB will be more of an aesthetic issue. Also, many papers state that you should paint/varnish your diffusers to minimize absorption and increase diffusion by having a harder, sealed surface.

This whitepaper discusses sealing versus not sealing wood diffusers (Section 3, Figure 2).
