UltraTouch Natural Fiber, speaker damping

jetty2 · 30th August 2007, 10:13 PM

Has anybody tried this material to see if this makes a good dampening material for speaker cabinet?

http://www.bondedlogic.com/ultratouch.htm

here are the NRC values

Size Thickness 125 250 500 1000 2000 4000
R-13 3.5” .95 1.30 1.19 1.08 1.02 1.00

It seems to be better than whispermat on NRC figures.

Feedbacks and comparison with other materials are appreciated.

Hi,

Looks fine for damping a cabinets airspace, but not the cabinet.

I've been using it for damping in my U-baffle setup. Very nice. Nicest damping material I've found in my 35 years of messing around with speakers.

The only down side is a small amount of the boron based fire retardent that they use for critter, mold, and fire control will sift out of the cotton. This is a temporary condition and stops after a few weeks.

Could you elaborate?

Thanks

My replies show up a bit out of order as I am new in the forum, I meant stern elaborate on his comment :-)

Anyways, back to ultratouch, I happy to see somebody using it successfully. I am getting some samples to test and measure its effectiveness.

In what way is that a problem, dust? They seem to be perfectly safe for use.

It only shows up as a fine white powder on the bottom surfaces of the baffles. Not really a problem. Cleans up easily with a vacuum cleaner with fuzzy brush attachment.

After a couple of vigorous exersize sessions playing pipe organ music at insane levels no more powder is coming out of the damping...
