Description
Boston's new PowerVent subwoofers deliver the dynamic bass foundation that is essential for
lifelike reproduction of movie soundtracks and music in the home.
All the new subwoofers utilize rugged DCD™ (Deep Channel Design) bass units built in
Boston's state-of-the-art manufacturing facility in Peabody, Massachusetts. Every one is tested
as it comes off the line to be within ±1dB of the lab reference unit, an incredibly tight tolerance.
The amplifiers have built-in variable crossovers that make it easy to achieve a seamless blend
with the main speakers, while 24dB/octave low-pass filters prevent the subwoofer from being
easily localized by ear, increasing placement flexibility. A crossover bypass position is provided
for use with home theater electronics that perform their own bass management functions.
Because of their high-powered amplifiers and computer-optimized tuning, all three models are
capable of impressive deep bass and high output from remarkably compact enclosures. In addi-
tion, they all feature BassTrac™, a proprietary new Boston-designed circuit that tracks the input
signal to the subwoofer and prevents its amplifier from being driven into audible distortion. The
benefit: The bass stays clean and strong at any listening level.
Auto on-off amplifier switching and easily accessible controls make the PowerVent subwoofers
as convenient to use as they are exciting to listen to.
