ABSTRACT:
An acoustical device for damping and absorption of certain frequencies in a room and including a surface which functions as a low pass filter to maintain low frequency absorptive properties without reducing the acoustical brightness of the room. The device may be embodied as a piece of free standing room furniture. A capped tube of the device defines an internal ambient air chamber. Exteriorly of the tube is a perforate sound reflective member. The perforation size and spacing function as a mechanical low pass cross-over system. A cross-over option is presented to include an imperforate limp mass sheet covering at least partially the absorbent tube surface.
