Subwoofers

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 four of the new subwoofers utilize rugged, long-excur-

sion bass units built in Boston's state-of-the-art manufactur-

ing 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 cross-

over 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 ampli-

fiers that deliver high power with low distortion. Our

amplifiers use a linear output stage for superior sound

quality, and a digital tracking power supply that delivers the

required output voltage without power line "sag" or exces-

sive thermal buildup.

Because of their high-powered amplifiers and computer-

optimized tuning, all four models are capable of impressive

deep bass and high output from remarkably compact enclo-

sures. 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 con-

trols 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 * RadialVent™ cooling is coupled with a 10-inch rear-firing passive radiator for bass that excites your senses.

PV800 With its Boston-built 12-inch (300mm) woofer and 300-watt amplifier, the PV800 is a powerful answer to those seeking the best bass reproduction for their home entertainment system. The down-firing driver features DCD™ (Deep Channel Design) technology. Using Finite Element Analysis computer modeling to optimize the driver's magnetic structure, we cut a groove in the poleplate, increasing voice coil excursion, while maintaining the driver's high efficiency.

PV1000 Technical Highlight: RadialVent™ Cooling It's an immovable law of physics: If you want deep bass response from a small enclosure, you need lots of power. There's no way around it. In the case of the PV1000, we use a high-efficiency 1000-watt amplifier to get response down to 22Hz from a remarkably small cabinet. But high power is only half of the equation. We also need a rugged, high-output bass driver that can handle 1000 watts safely.
