Here's a question for you people.
For use as acoustic insulation in a cabinet, which would you rather use, and why? Cleaned and carded sheep's wool, or Dakron polyfill ,or acoustic tile/matting ?

what typ of box?
ported i like sleep skin (cleaned wool) better bass for SQ

also you told me

I use polyfill although I'm sure using cleaned sheep's wool has a bit of an audiosnob appeal to it but polyfill is cheap to buy and find.

what??? no trunkliner sprayglued to the walls?? [img]tongue.gif[/img]

For me - Dacron polyfill. Cheap, easy, almost the same performance of the expensive stuff [img]graemlins/thumb.gif[/img]

i use a egg crate foam with polyfill, i use the foam because i get it for free, polyfill for the $$$ is the way to go

If anyone can hear the difference between polyfill and wool I will buy them lunch!

I might try a mix of crumpled up newspaper and old oily rags......should sound great.

the oily rags will stat a fire that will light the papper it will sound great for the firemen as they hear what a sub sounds like when its on fire :)
and where i'm i going for lunch becouse you can hear the difference between the two
WOOL IS THE WAY TO GO

You can hear the difference?

Lets do a double blind test.

I have wool in my pillow top, I know it is the way to go in that application!

I forgot to mention Laundry Dryer Lint ;)
I'm not just talking for subs here.
I think the biggest diff. is in the mid-bass/midrange area. There seems to be more coloration with synthetics IMO, no [img]graemlins/bs.gif[/img] .

Polyfill -- won't the wool absorb moisture?

As for double blind tests... unless both boxes are loaded into the car on an a/b switch with matching levels, the test is invalid -- in car response varies too much for the showroom to matter.
