Sound Diffuser Build Gallery

To help get your creative juices flowing, here are some examples of the sound diffusers people have built using these blueprints. This is just a small selection of the DIY diffuser build photos people have sent me. If you have photos of a build you're happy with and you'd like me to post them, please email them to .

If you've not yet grabbed the blueprints, you can download them for free here. For more information about these optimized stepped diffuser designs (and acoustic diffusers in general) visit the sound diffusers 101 page or download the diffuser design thesis.

Castle Mastering Studio uses 7 Leanfuser™ panels on rear wall

Audiobomber's Castle Mastering Studio uses arrays of Leanfuser panels on the rear and side wall. This studio is built inside Castle Wildberg, a medieval castle in Upper Austria! Built by owner and mastering engineer Alexander Jöchtl (better known as Audiobomber). Castle Mastering features other acoustic treatments built by Alex, including DIY bass traps and ceiling clouds.

Stepfractal™ fractal diffuser array built by Kalakula Studio

Stepfractal diffusers built by Steven Mazzotta at Kalakula Studio, Atlanta, GA. The fractal cells are made out of basswood, carved with a dado saw and mounted on vertical panel cuts. Build process is shown below.

Plywood Leanfuser™ panel array (modulated) built by Chris Rude

"This diffuser build was very inexpensive and despite the cheap materials, I think it looks great!

More importantly, I immediately noticed the difference in my space, where the flutter echo in my basement studio was instantly transformed into a much more pleasing reverberation.

The finish is just 2 coats of lightly tinted poly over plywood. Very inexpensive, but when you cut across the grain of the plywood, you get a cool tiger stripe effect.

My zero depth wells are made from painted MDF to make each module look smaller and help break up the overall girth of the object.

I am very happy with the finished product!"

Modified Leanfractal™ (with wells) built at Sanford Brown College

Jeff Sansone, the audio production lead at IADT School of Technology (Sanford Brown College), build this fractal sound diffuser out of poplar.

The design is based on the 7-module Leanfractal, but fins (separators) have been used between the wells. Note that the Leanfractal was designed to function without fins, so the effect these fins have on diffusion performance is unknown. The fins give the diffuser an aesthetic similar to a fractal QRD diffuser (like the RPG Diffractal).
