SK Saturn diffuer

Didn't see any reference here....

Claims to have a 120degree radiation angle, although no testing appears anywhere.

Suppose they are 2 D? They don't seem to be damped at all, so some absorbent behind them may pose as double duty.

Opinions? They seem to be economical for us small/home studio.

I got a reply from Steve Klein himself:

They are not dampened but can be easily. In a grid it is not an issue, on the wall we usually put some filler in, depending on distance, quantity, taste. Whatever their resonance is, it is quickly attenuated.

Never tested, but a radius characteristic is 120 degrees. Angle of incidence is a major factor.

Freq response can be safe to say it will go to ¼ wavelength.

Very smooth, musical device.

Let me know how I can help.

Steve is one who created the wood slat dealio. I've seen them somewhere before. Looks like a simple DIY project ...if they work?? And weigh a TON 8O
Saturns will go to 1/4 wavelength??? Of what full spectrum ???? :lol: :wink:
NO opinion on the Saturns????

wood slats? I dunno-they are supposedly custom built.
Saturn? suppose its light- ABS.

Like these GIK-things.
Always good for narrow band absorption.

Calculating 1/4 wavelength for the depth of the Saturn diffuser (5") would be @ 675 hz- if it was flat. Anyway to calulate the high end? Or would it be a waste of time?

Guessing that the raised "+" or " x" design aids in the diffraction/scattering.

For $55 a pop, it might be worth a risk. Though I couldn't organize a correct test to its effectiveness with out a anechoic room, I suppose a simple measurement would show some sign of use.

Bert,
GIK -things? Are you reffeing to the D1's?

Light weight = prone to resonate = bad for diffusion. better to use something with some real heft to it so you get more redirected bounce and less wiggle/re-resonate

And it taint the depth that matters as long as the chord height of the surface curvature is suffiecient... the frequency of the longest wave perturbed is inverse to the height/width [bigger device = lower freqeuncy of efficacy limit]. If not square, use the lesser H/W dimension... but here we got 2'x2' so - ya reckon that unit works down to about 100 Hz???

Scott- 100hz? you think? hmm.

Light=resonant - have to agree on that. Some foam in place stuff from HomeDepotulant should remedy ?

yep that would help i reckon - but if you have to start dinking around with the units i got to ask myself how hard it would be for you to make a set of heavy bent plastic or wood 2x2' panels from scratch. $55 seems a bit steep if the part aint ready to go to work right out of the box.

my $0.02

100Hz sounds a bit low to me fpr a 2x2', but with an optimal mounting maybe it could do some good that low [probably not in a ceiling grid] - in that kind of mount maybe more like 250 Hz???

True, out of the box would be nice. I appreciate your thoughts on that, as they echo mine. It does have an appealing aesthetic quality to it, however. Normally I go for purpose over bling bling :lol: I may be looking at a easy way out with my temporarily handicapped dominant right hand from an injury recovery :evil:

Making some head way with the coupled room deal, more on that later.
