Diffusers for magnepan speakers


Looking for thoughts on building a skyline diffuser panel the same size as a maggie 1.6 to place behind speakers. Asking for advice because my online reseach mentioned a 2x2 panel for general specs. i do not want to waste the time and money if it would not sound good. I am thinking about three 2x2 panels placed on stands behind the speakers about 3.5 feet. Any thoughts would be appreciated.

There are a few companies that make nice kits for a fair price. The fit and polish after completed look very pro. I would just Google diffuser kits and your there. Has far as wasting time and money. Treatment such as this can be a crap shoot so if they don't achieve what your looking for sell them on the Gon.
For building a skyline diffusor, you may want to check out gearslutz.com and go to the studio building and acoustics forum and the sub-forum for bass traps, acoustic panels, etc. There is alot of DIY info about all types of acoustical treatment, including diffusors.

By the way, I recently put two GIK Acoustic diffusors behind each of my Magnepans. The two together measure 4 feet tall by 2 feet wide. I mounted them on the wall, which is about 5 feet behind the speakers. In my case, the diffusors behind the Maggies have made a significant improvement in the sound. In addition, I put a GIK Tri-Trap on the floor against the wall behind each Magnepan. Now I hear bass and kick drums like I never thought I would on a Magnepan.
