Acousta-Fill, 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-Fill is less expensive than long fiber wool and does not have the problem of harboring moths. Acousta-Fill also outperforms Dacron, foam, and fiberglass.
Acousta-Fill 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-Fill and no mask or gloves are needed when using this product. 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.
