Boston’s PV350 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 surround sound system with its impressive bass output and compact size.

This subwoofer utilizes our rugged DCD™ (Deep Channel Design) 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 low-pass 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 strong amplifier and computer-optimized tuning, the PV350 is capable of impressive 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.

C o n n e c t i o n s

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 frequencies to the subwoofer power amplifier.

Speaker level: Use these high-level terminals with receivers that do not have a subwoofer output. The speaker inputs accept both left and right channel speaker signals from your receiver.
