ABSTRACT:
A loudspeaker enclosure has a loudspeaker driver mounted on a surface of the enclosure such that the driver has an exposed front face to produce sound waves which are sought to be transmitted to a listening space exterior of the loudspeaker enclosure. A plurality of successive spaced limp or semi-limp non-porous pliable barriers are positioned in an opening between the interior and exterior spaces of the enclosure so as to relieve rear pressure of the loudspeaker driver while attenuating the rear sound waves and providing a damping effect on the loudspeaker driver.
