Rix,
Thanks for the quote above. Makes good sense.

IRT BAD, it looks like they are using absorption in those. The ones I've made are hollow & capped top & bottom. I did try these with wool balls inside them & liked it better (in my room) without.   

Rix,
Absolutely at some point I will experiment with more diffusion behind the speakers. I like this "effect" better than absorption. 

As far as moving forward... I've been experimenting with diffusion in the room corners lately. That being... Taking 8' long 3" I.D. cardboard tubes (I get bar stock shipped in these types of tubes) and drilling approx. 125, 5/8" holes in them (somewhat equally spaced all the way around/top to bottom), then covering them with with plastic mesh material & capping top & bottom. This has also helped with overall system clarity, although to a lesser degree than the wall-type diffusion panels.  

+1 Rixthetrick! 

Thanks rix. I also have one of mine (30" X 40") on the front wall between the speakers. That one is about 3' off the floor. Very happy with the results even though they are not quadratic. For the side walls I'm using a combination of absorption & diffusion. 

rix,
Please let us know what you think once they are positioned where you want them in your room. 

Thanks

That one looks great. I have no experience with it but... IRT diffusers, my experience is they can improve the soundstage to a remarkable degree. They added clarity & detail to my system, which was already very good. I made my own (40" X 30") and have it centered on the front wall behind/between the speakers.
