Description
Boston's XB4 subwoofer delivers the dynamic bass foundation that is essential for lifelike reproduction of movie
soundtracks and music in the home. This attractive, powered subwoofer will complement any stereo or home theater
sound system with its impressive bass output and compact size.
This subwoofer utilizes our rugged Deep Channel
engineering 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 amplifier has a built-in variable crossover that makes it
easy to achieve a seamless blend with the main speakers, while a 24dB/octave lowpass filter prevents the
subwoofer from being easily localized by ear, increasing placement flexibility. A crossover bypass function is
provided for use with home theater electronics that perform their own bass management.
Because of its high-powered amplifier and computer-optimized tuning, the XB4 is capable of impressive deep bass
and high output from a remarkably compact enclosure. In addition, it features BassTrac
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 XB4 subwoofer as convenient to use as it
is exciting to listen to.
