Description
The Lynnfield VR965 and VR975 deliver accurate, wide-range performance that conveys all the
power and impact of the most demanding program material. These floorstanding speakers
combine integrated powered subwoofers with Boston-built midranges and tweeters into sleek
cabinets that blend gracefully in any listening room.
Both models feature high-current subwoofer amplifiers driving our long-excursion, Deep
Channel Design (DCD
both feature BassTrac
the subwoofer and prevents its amplifier from being driven into audible distortion. Unlike con-
ventional limiters, BassTrac preserves the waveform's shape, maintaining the fidelity of the sig-
nal. The benefit: The bass stays clean and strong at any listening level. For user convenience, an
auto on/off function turns the subwoofer amplifier on when a bass signal is sensed, and turns it
off approximately fifteen minutes after the last signal is received.
Our midrange units feature copolymer cones, butyl rubber surrounds, and a computer-
optimized magnet structure for smooth, accurate midrange reproduction. A 1" (25mm)
anodized aluminum Lynnfield VR tweeter, with our exclusive Amplitude Modification Device
(AMD), produces extended, sparkling high frequencies.
The cabinets are constructed of Medium Density Fiberboard (MDF), chosen for its outstanding
acoustic characteristics, and have extensive internal bracing. The result is superb structural
integrity that eliminates the spurious resonances and vibration that degrade the sound of ordi-
nary speakers.
MagnaGuard ® magnetic shielding ensures the speaker's magnetic field does not interfere with
the television's picture, allowing placement next to a TV in a home theater system.
