SS-ACLF-424C cotton bass absorption panels are the absolute highest performing low frequency absorption available. Made from 100% Class A nonflammable material, SS-ACLF is at home behind screens, in pillars and in corners. They are also used behind triangle corner traps to increase low frequency absorption.

The SS-ACLF-424C panels work well because of the random thread length, diameter and orientation.
