bass foundation that is essential for lifelike reproduction of
movie soundtracks and music in the home.

All four of the new subwoofers utilize rugged, long-excur­sion 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
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.

The PV800 and PV1000 use special high-efficiency ampli­fiers that deliver high power with low distortion. Our
amplifiers use a linear output stage for superior sound

1dB of the lab reference

quality, and a digital tracking power supply that delivers the
required output voltage without power line "sag" or exces­sive thermal buildup.

Because of their high-powered amplifiers and computer­optimized tuning, all four models are capable of impressive
deep bass and high output from remarkably compact enclo­sures. In addition, all four units 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. Unlike conventional
limiters, it preserves the waveform’s shape so the fidelity of
the signal is maintained, while preventing 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.

PV1000

The PV1000 is proof that powerful
things come in small packages. Here is
a subwoofer that delivers stunning low
frequency performance while occupy­ing barely over one square foot of
floor space.

Advanced Boston technology makes
this performance possible. A 10"
(250mm) down-firing long-excursion
bass driver with cast aluminum basket
and patented
coupled with a 10-inch rear-firing pas­sive radiator for bass that excites your
senses. With its 1000-watt, high effi­ciency amplifier providing the driving
muscle, the PV1000 is the subwoofer of
choice for the most demanding music
or home theater systems.

Front-mounted volume, crossover
frequency, bypass, and phase controls
are easy to reach, making it simple to
achieve the optimum performance.

PV600

We believe the PV600 redefines the
price/performance relationship for mod­erately-priced subwoofers. In terms of
low-frequency extension, maximum
output, and freedom from audible dis­tortion, the PV600 sets a new standard
at its price.

The key to its outstanding performance
is its Boston-built 10-inch (250mm)
bass driver. Manufactured on Boston's
state-of-the-art assembly line to a toler­ance of ±1dB, this driver features a
long-excursion DCD voice coil and a
high-mass, low-resonance diaphragm
for response down to 29Hz (-3dB).

The dual 2-inch (50mm) down-firing
ports are flared at both ends to reduce
audible turbulence. The high-current
120-watt amplifier has both speaker­and line-level inputs, as well as a cross­over bypass position. A front-mounted
volume control makes it easy to adjust
the bass to the desired level.
