Pritex, 30kg/m3, 50x100cm, d=28/42mm
PRITEX is a flame retardant polyester foam with a dark gray color and high specific mass, specially developed for acoustic purposes. Its height is 42 mm and it is particularly suitable for all types of cabinet wall damping, functioning even better in a TL than longhair wool.
It is also ideal to mount directly behind a woofer or midrange to prevent backlash. It is absolutely the best damping for bass-reflex. The packaging foam or mattress foam (of polyether) offered under many names (also pritex!) is completely unsuitable for cabinet damping. A thinner version (28 mm) for small bass reflex housings is also available.
