Description
The Boston PV1000 PowerVent
is essential for lifelike reproduction of movie soundtracks and music in the home.
The key to its impressive performance is its rugged 10" bass driver with patented RadialVent™
cooling technology. This innovative design gives it tremendous power handling capability, for
exceptionally clean output even at high levels. The driver's basket is made from die-cast aluminum,
which keeps all the critical moving parts in precise alignment. The PV1000's bass unit is 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 amplifier is a special high-efficiency design with a digital tracking power supply that minimizes
unwanted heat buildup. The output stage is a linear type, for excellent sound quality and high reli-
ability. BassTrac™, a proprietary Boston-designed circuit, 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. The subwoofer has a built-in variable crossover that makes it
easy to achieve a seamless blend with the main speakers, while a 24dB/octave low-pass filter pre-
vents 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 man-
agement functions.
The user controls are easily accessible on the front panel, making the PV1000 as convenient to use
as it is exciting to listen to.
