Quadratic Diffusers

I use tapered dual truncated conic wedge in cork a notably durable soft wood diffuser in a 3D holding structure, hand carved to inaccurately approximate an antique bowl. I place the diffuser bowl assembly on a leather and wood stand executed in the Eastlake furniture style. Presently the effect of added richness is greatest with a slight bias to the R channel. Some would say, they are just hundreds of wine corks…..i beg to differ….

RPG good 2 

but congrats Rix - you already know more than you know…..

@tomic601
I trust that an adequate amount of research into good tasting wines was invested in your dual truncated conic wedge diffusers of choice?
Such research done with music, seems like a worthy quest for an enjoyable evening or two..three.. loads of them by the looks of it :-)

but congrats Rix - you already know more than you know…..

Right now, mine do look remarkably like a science project - they do sound great though. And my wife is still ok with it, anyone might think she's becoming an audiophile?!!

Apparently it's what I don't know, that I don't know, that is the greatest potential for improvement.

@boxer12 -  Are you going to try more diffusion between the speakers? Please circle back and share your findings as you move forward. These diffusers took me quite some time, Saturdays mostly, every now and then.

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.
