Quadratic Diffusers

I'm looking over the GIK Gotham N23 5″ Quadratic Diffusers. 

Anyone have any experience with these or similar? Care to comment?

What did you think of their construction, hanging hardware, aesthetics, effects on the sound, placement ease or difficulty?

absorption and diffusion are two faces of one entity called 'acoustic optimisation'.

their mutual balance totally determines correct presentation of highly valued musical criteria for reproduction quality:
spatiousness, presence, focus, ambiance, directness, convincing power, non-coloration and dynamic contrast

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.
