Product Description
Acousta-Stuf, a synthetic material made from crimped fibers, is an excellent choice for filling or stuffing small enclosures or transmission line cabinets.
Key Features:
Acousta-Stuf Polyfill 1 lb. Bag Speaker Cabinet Sound Damping Material
Acousta-Stuf, a synthetic material made from crimped fibers, is an excellent choice for filling or stuffing small enclosures or transmission line cabinets. Long fiber wool has been a favorite among serious speaker builders but Acousta-stuf is less expensive than long fiber wool and does not have the problem of harboring moths. Acousta-Stuf™ also outperforms Dacron, foam, and fiberglass.
Acousta-Stuf sound absorption damping fiber deepens bass, provides cleaner midrange, and improves the dynamic extension of any speaker system. There are no health hazards with Acousta-Stuf and no mask or gloves are needed when using this product; the melting point is a very high 490°F. Most sealed and vented enclosures require 1/2 lb. of damping material per cubic foot of enclosure. For best results it is recommended to loosely fill the material throughout the enclosure.
Key Features:
- Higher performance than natural fibers, easier to use than fiberglass
- Improves bass, tightens midrange, increases dynamics
- Super-stable, won't decompose, doesn't attract insects
- No mask or gloves required!

No, not the one in your head - the space inside those cheap loudspeakers you bought! Stopped my Yamaha 3-ways from resonating at high volumn.

This is a small sealed box for a 2012 Mustang I should have bought two bags because it could have took one bag and a half to fill this box properly but I stretched the one bag and made it work and I also glued it to the sides with the spray glue worked great and gave my Bucks A Better Sound overall pretty expensive though

I recently assembled a pair of GR Research desktop Mini loudspeakers. I needed some acoustic stuffing, and this fit the bill perfectly.
