DIY Acoustic Diffusers

Hi,go to the PME RECORDS site.Under tech support they have a diffuser that is very easy to build.Cost about 12 dollars each,18x18,takes about an 1.5HR to make.I cut mine on a miter saw .This is the simplest and best one I have found.

These are great recommendations! Thanks to all, and if there are any other DIY solutions, please keep 'em comin'.

For anyone looking for Diffusers at a resonable price, take a look at this website:

www.waveguideacousticsolutions.com

These are 30" x 30" and other sizes are also available. 2.5# density hard closed cell foam blocks mounted to 3/8" plywood and then spray coated with flat black paint(other colors available) It's like DIY, yet the DIY has been done and the price can't be beat! Take a look and you be the judge

These are also sold on ebay for a discount price from time to time. . . .check it out, let me know what you think! I'm a DIY guy that knows first hand the high prices of commercial offered acoustic treatments. Hope my offering helps and I hope to be a part of your acoustic treatment solution
