Connections
Line level: Use the jack labeled “line level in” with most systems. These inputs accept the line level signal from your
receiver’s subwoofer output. The subwoofer’s circuitry filters out the high frequencies and sends the remaining low
fr
equencies to the subwoofer power amplifier
.
Speaker level: Use these high-level terminals labeled “speaker level in” with receivers that do not have
asubwoofer output. The speaker inputs accept both left and right channel speaker signals from your receiver.
Description
Boston’s XB2 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
®
Design (DCD) bass unit designed in Boston’s state-of-the-art
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 front/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 str
ong amplifier and computer
-optimized tuning, the XB2 is capable of impr
essive deep bass and
high output from a remarkably compact enclosure. In addition, it features BassTrac
®
, a proprietary 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 almost any listening level.
