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 addition, 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.

Connections
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged.
The auto-on circuitry only activates or deactivates the power amplifier. Make sure your
subwoofer and receiver are unplugged when making the connection.
Line level: Use the 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 subwoofer
output. The speaker inputs accept both left and right channel speaker signals from your receiver.
Connecting Your Subwoofer to Digital 5.1 Channel
Home Theater Systems
Digital 5.1 home theater electronics dedicate one channel (the “.1” of 5.1) to reproduce the
special low-frequency (LFE) information (such as explosions and thunder) contained in digitallyencoded soundtracks.
Select ”subwoofer-yes“ from your receiver’s set-up menu. Hooked up this way, the receiver’s
amplifier is relieved of having to reproduce the difficult low bass signals that can drive the
receiver into audible distortion.
Use an RCA cable (not included), as shown, to connect your digital receiver’s subwoofer output
to the subwoofer. Use the bypass crossover control input. On the PV400, set the crossover to the
direct position and connect to line level in.

If you do not wish to run RCA cables to your subwoofer, you may use speaker wire to connect
the subwoofer in parallel with your main speakers. The subwoofer does not present any additional load to your receiver.
Select “subwoofer-no” from your receiver’s set-up menu. This sends the LFE signal to the main
left and right speakers, and thus, to the subwoofer. Consult your receiver’s owner’s manual for
more details.
When using the speaker wire hookup, the subwoofer’s built-in crossover is engaged. As a starting point, set the crossover control on the subwoofer about 10Hz higher than the lower limit of
your main speakers’ bass response. Fine-tune the crossover setting by ear for the smoothest
blend with your main speakers. The best setting of the crossover control will depend on speaker
placement and personal preference.
Be sure to connect + to + (red) and – to – (black).

Controls
Volume: Adjusts the sound level of the subwoofer. A typical setting is around 10 o’clock.
Crossover (Hz): Adjusts the frequency of the low-pass filter for the subwoofer.
Polarity (0° or 180°): Selects regular (0°) or inverted (180°) polarity for the subwoofer. Set this
switch to provide the fullest, most dynamic bass. The distinction of phase will be most audible
on low-frequency percussion instruments or music with a continuously repeating bass line.
Power off/auto/on (PV800 only): Set to auto, the PV800 turns on automatically when a signal
is presented to it. Set to on, and the PV800 will stay on all the time.
The PV600 and PV400 have auto-on circuitry that turns the subwoofer on when a signal is
presented, and turns off if no signal is detected for 15 minutes.
NOTE: Power is always supplied to the subwoofer electronics unless it is unplugged. The autoon circuitry only activates or deactivates the power amplifier.
The PV600 and PV800 volume control is on the front of the subwoofer.

Placement
Place the subwoofer next to a wall or in a corner near your main speakers. Typically, the sound
is best when the subwoofer is within 15 feet (5m) of the main speakers. However, the sharp
24dB/octave crossover roll-off permits placement farther from the main speakers if necessary.
Since the ear is unable to localize the low frequencies of the subwoofer, the bass still appears
to come from the main speakers. In most cases, the subwoofer may be placed anywhere in the
listening room.
The level of bass output from the subwoofer will vary at different positions in a room. When placed
near walls, its loudness is emphasized. Corner placement provides the most bass output, while
placement near only one wall will provide somewhat less bass. Placement completely away from
walls may produce too little bass. Regardless of how you place the subwoofer, you can adjust the
subwoofer’s level with its level control. If you move the subwoofer, recheck the setting of the polarity switch. Use the setting that yields the louder and more dynamic sound.
IMPORTANT: Do not place the subwoofer where there is a chance of contact between the rear
panel heat sinks and drapes or furniture. Avoid obstructing air flow to the back.
