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.

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.
i am drawing the conclusion that magnepan has been responsible for more audiophiles tweaking everything than any other manufacturer. i of course have ficus trees, tape on floor to mark location, tube traps, acoustic panels, homemade stands and braces and razor treatment, cones, new crossovers, specially chosen wires, electronics etc to make my 600 dollar mmgs sound good. and i loved every minute of it. where else could i have had this much fun legally??? btw.. they sound pretty good
For some reason, Magnepan is a lightning rod for DIY.

I've got he bug, too......and taking the woodshop classes to prove it.
i didn,t like acoustic treatments hung behind my mmgs speakers but they are easy to move and experiment with. your room is the same shape as mine but i have pictures, books, cabinets, wall art/objects everywhere. a neat freak would have a nervous breakdown here, ha. i use 2 cathedral panels behind my listening seat and 2 more on the sidewalls at the pt of first relection. i do have tube traps and roomtunes in the corners of the room. i still don,t have things perfect but i doubt i ever will. good luck
