Acoustic Sciences Corp. (ASC) is introducing a new accessory for music playback systems and home theaters. The SubTrap™ is an acoustic subwoofer stand that can improve the low frequency sound of listening environments, and will be available only through dealers. The SubTrap is a product designed to eliminate the vertical resonance of subwoofers – the low frequency energy that bounces between the floor and ceiling and causes unpleasant one-note bass. Utilizing the acoustic technologies found in the ASC TubeTrap™, the SubTrap is effective in the 70Hz range, which is where most coupling occurs for the average 8-9’ ceiling.

RBH Sound Inc. introduces the MS-10.1 subwoofer featuring dual 10-inch drivers and proprietary Tuned Aperiodic Vent™ (TAV™). This new subwoofer was designed to compliment RBH’s existing Compact Theater 5.1 and 7.1 speaker ensembles, but is available separately for the consumer simply looking for a powerful, yet affordable subwoofer. RBH is a company that truly believes in the “trickle-down” theory. When they develop a new innovation for their flagship Signature Series, their other lines invariably benefit. Such is the case with TAV technology. First developed for the 1212-SE subwoofer, Tuned Aperiodic Vent™ (TAV™) technology bridges the gap between vented and sealed enclosure subwoofer designs providing deeper low frequency extension than similar sized, sealed designs. TAV™ technology shifts the vent tuning to a much lower frequency than would otherwise be possible in a small-vented enclosure and also improves transient response. Another “trickle-down” technology that ...

Bowers & Wilkens has just announced the release of their new spherical shaped subwoofer. The PV1 Pressure Vessel Subwoofer breaks ground from all previous designs with a unique, spherical enclosure and all-new driver and amplifier concepts. “The PV1 doesn’t look like any other subwoofer, and its performance is equally uncommon,” says B&W Loudspeakers Executive Vice President Chris Browder. At the same time, the B&W industrial design moves the subwoofer from its traditional dark corner to pride of place, front and center, in today’s new-tech, “lifestyle” AV systems.

Polk Audio has just announced the introduction of the new LSiW high performance powered subwoofer. It features patented Polk Audio technologies and features for home theater and music performance. The LSiW features dual 10" drivers with high roll surrounds and 2 inch voice coils mounted on opposing 1" thick MDF baffles. The top, bottom, front and back panels of the enclosure are finished in black high gloss laminate and the side panels are finished in either Cherry or Ebony-finish wood veneer.

RBH Sound Inc. has just introduced the 1212-SE, a dual long-throw, 12-inch, 400-watt class A/B powered subwoofer that uses TAV™ technology for increased performance with a smaller cabinet size. Tuned Aperiodic Vent (TAV) technology bridges the gap between vented and sealed enclosure subwoofer designs providing deeper low frequency extension than similar sized, sealed designs. TAV technology shifts the vent tuning to a much lower frequency than would otherwise be possible in a small-vented enclosure and also improves transient response.
