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?

I looked for skyfusers a while back. Alot of options out there. I ended up with Vicoustic DC2. Largest area for the price, can easily be mounted with double sided tape on ceiling or walls and was inaudible from the wood versions.
@hilde45 - So it's been a few months, what have you ended up doing?

Today I finished the second of four QRD17 diffusers, I used linseed oil and they look beautiful. Next task is placement, and finish off the last two diffuser assembly and oiling. I had no idea that they'd be as heavy as they are.

I am going to try them between the speakers on the front wall first.

Anybody who's got quadratic diffusers I'd like to hear from you as well?

Have not done anything yet because have been having a new room built. How hard were yours to build?


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

Thanks
@hilde45 - I had no idea how much I'd need to learn, and the amount of work involved when I took upon myself to have a go at it. I took logs of cherry wood and split them with a band saw, rant them through a thickness planer and joined them to make 17" boards, 5' long.
If I'd not chosen to make them from solid cherry (the backing board is actually Birch ply board) I am sure it'd gone a lot easier.
Running 60 of the 1/4" boards for dividers, 8 sides, 8 tops and bottoms through the CNC router table was easily the quickest part of the job.
It's what I can do now that I've learned, now that's exciting.

Next will probably be the equipment rack.


@boxer12 - I first want to try them between the speakers on the front wall, just the first two for now. I have a frame with absorption, and I want to keep the bottom of the diffusers up off the floor, so I have free space to run cables etc.
