The BPVX is built to the same high construction and performance
standards as Definitive’s main left and right front speakers and
include features like high-definition bass/midrange drivers with butyl
rubber surrounds, wide-dispersion pure aluminum dome tweeters with
magnetic cooling fluid, complex Linkwitz-Riley crossover networks and
solid monocoque cabinets with diffraction-less grille/baffle
interfaces. It can be mounted to a wall with the supplied plate or
placed on a shelf or stand for the ultimate in surround sound realism.
The Bipolar Advantage
Definitives's BPVX bipolar surround speaker is simply the best
available. It’s a true bipolar system containing two complete
full-range speaker systems, one on each side of the cabinet. Bipolar
technology is absolutely superior for surround speakers because it
combines the

performance
advantages of direct radiating (imaging, focus, localization, and
specificity) and dipolar speakers (spacious, all-enveloping ambience)
into one ideal system which is perfect for all multi-channel formats.
The BPVX is a full-range, extremely linear, low-distortion system which
is timbre-matched to blend perfectly with all Definitive BP and Studio
Monitor series speakers as well as other high-quality speaker systems.
The BPVX tremendous dynamic range as well as true high-definition sound
quality combined with its bipolar radiation pattern results in total
immersion in the sound field. Home Theater said of Definitive’s
bipolar surround speakers "they're actually better then dipoles for use
with Dolby AC3 [Dolby Digital] digital surround systems." Video Magazine raved: "They make all the difference in the world...you feel like you're part of the movie." Sound & Image
completely agreed: "The size of my room shifted almost effortlessly as
the action on my TV moved from one acoustically distant environment to
another...all of a sudden the walls of my living room melted away;
strange birds called in the distance, and something large was
sluggishly making its way through the underbrush."
Bipolar Surrounds are the Easiest to Use
Definitive's bipolar surrounds are designed for easy and unobtrusive
placement in your room. Easy-to-use mounting plates are included for
wall mounting. Positioning is non-critical; unlike dipolar surrounds,
which are limited by their specific sidewall placement requirements,
Definitive's bipolars may be located on the sides or rear of the room
(or both as in 6.1 and 7.1 channel installations) or on the ceiling.
They may be mounted on the rear wall (with their front drivers shooting
towards each other and their rear drivers shooting toward the side
walls) with excellent results.
Non-Resonant, Low-Diffraction Cabinet Maintains Sonic Purity
The resonant vibration of a loudspeaker's cabinet walls and baffles can
also impart coloration. The monocoque cabinets of all Definitive BP
surround models are constructed of extremely thick, dense medite with
foam damping pads and extensive internal bracing. This virtually
eliminates cabinet vibrations and resonance which would otherwise
interfere with the pure sound produced by Definitive's high-definition
drivers.
Definitive's High-Definition Die-Cast
Basket Drivers are an Engineering Marvel
The BPVX features four 6-1/2 inch high-definition cast-basket
bass/midrange drivers for significant performance advantages in the
areas of bass reproduction, lifelike midrange clarity and dynamic
range. These sophisticated drivers are engineering marvels which
incorporate deeply drawn mineral-filled polymer cones, combined with
butyl rubber dust caps and surrounds, high temperature vented voice
coils and massive magnet structures. This combination of features
assures high definition, superb transient response, high efficiency,
high power handling and extended linear response. In addition, the
aerodynamically designed, non-resonant, cast-magnesium baskets minimize
reflections of the sound radiating from the back of the cones and
preserve structural and magnetic integrity.
Definitive's Moving-Coil Pure Aluminum Dome Tweeters
The accuracy of high frequency reproduction really sets apart a great
loudspeaker. The magnetic fluid-cooled moving-coil pure aluminum dome
tweeters Definitive developed for the bipolar SuperTowers are of a
unique design that synergistically brings together the performance
advantages of metal domes (greater clarity) and soft domes (smoother
sound and better dampening) in one state-of-the-art tweeter design.
The pure aluminum dome is specially annealed (to "relax" the crystal
structure) and acoustically loaded by a precisely configured acoustic
phase plug/lens (to assure perfectly controlled, absolutely linear
movement). The tweeter’s voice coil sits in ferro-magnetic colloidal
fluid which serves to cool the voice coil for exceptional power
handling and also damps the system for smoother response and sonic
accuracy. In addition, the unique silk surround provides better
dampening and wave termination. The audible benefits of all this highly
advanced engineering include velvety smooth extended high frequency
response (beyond 30 kHz), greatly reduced distortion, improved
transient response, notably higher definition and crystal clear
life-like clarity.
