Sound diffusers

I currently have CD racks at the first reflection points of my tower speakers (Von Schweikert VR-4 JRs) with the CDs spaced and staggered as diffusers. I would like to experiment with different diffusers when I move my CD racks. I’m cheap and am not willing to pay big bucks for commercial studio pieces. I also am not sure the cheap soft foam eggshell ones will be effective. I could buy those at Walmart. I think the diffusers need to be stiffer. I’m no good at woodworking or I would make my own. I know the brands GIK and Auralex are popular but I’m looking for something less expensive. Any thoughts would be appreciated.

Interesting that you mention fabric. My wife is a fabric artist and has made me large thick pieces which I drape behind the speakers for absorption. I need to put wool or synthetics behind those. I’m trying to tame the first point reflections at this time. The “skyline” boards are heavy and beyond me. The studios use hard panels of pointed cones in a fractal array. I wish I was skilled enough the make the panels described on arqen.com. Perfect and scientifically based but beyond my skills at this point.

I guess it comes down to what you consider to be "big bucks".  I paid $125 for a single 24x48 inch diffiuser/absorber from GIK that looks and works fantastic.  It's engineered to perform< I suspect, much better than some randomly organized CDs.   The sound impact is amazing in my space with these products.

True. And two would be all I need for my two channel set up. The speakers are 30” from the side walls and I only need two panels at the “mirror” points. Thanks.
