In an acoustical loudspeaker enclosure using cones and/or dome drivers, it i s known to be made of sheeting material such as MDF (medium density fiberboard), partic le board and plywood composites resulting in boxy cabinets of various dimensions. In this invention, a SONOTUBE (or other name brand) cement containment tu be replaces the box cabinet and becomes the main enclosure, the end cap containing the woofer (low frequency driver) being made of sheet material, and a round gabl e vent capping the other end and serving as venting for the woofer acoustical back wave.
