Quadratic Diffusers

@boxer12 - So I have finally (with help from a neighbour) put them up on a steel frame, about 14" off the floor. They are on either side between and behind the stand mounts on the front wall, 6" overhang outside of the back of the toed in stand mounts.
It's a bit rough and ready at the moment, and all about the sound and not looks, I'm afraid. My wife heard it immediately, it sounds richer.

I have the rear port of my speakers firing directly into some of the deeper wells in the diffuser, the bass is more defined. So much so, I'm really motivated to build the low frequency Activated Carbon Diaphragmatic Absorber. Diffusion is really as good and effective as I'd read.


@Hilde45 - My QRD17 plans were purchased from Acoustic Fields, and I really want to try their absorber I mentioned above, based upon the excellent results my wife and I are hearing.

The sound has becoming fuller and richer from the diffusion, clearer and more refined spacial information as well, compared to just heavy absorption on the front wall.

Wow!  Those really are alien.

@celtic66
Are you meaning the skyline diffusers?
Do yours look somewhat like a scanner barcode? I think they do look modern and clean / sharp. What do you think of their effect on your system's sound?

Yes, the GIK look like classy barcodes.  Mine are dark wood with black cloth 48” tall.  Top left corner of photo in weblink.  They work quite well sorting out errant waves and simply clean up the soundstage as designed.

+1 Rixthetrick! 

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…..
