Bipolar dispersion pattern (speakers on front and back) for totally enveloping surround sound that puts you in the action
The same highest quality components as Definitive's front channel speakers for seamless soundstaging
Two 5-1/4 inch die cast basket drivers and two 1 inch Pure Aluminum dome tweeters
Easy wall mount system included
Available only as a matched pair
The BP2X is built to the same high construction and performance standards as Definitive's main left and right front speakers and includes 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 BP2X is 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 BP2X 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 BP2X 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 of the room, at rear of the room, or both as in 6.1 and 7.1 channel installations. 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 BP2X features two 5-1/4 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 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.
Home Theater Systems
The BP2X makes the perfect choice for use in high performance multi-channel systems based on BP series main speakers such as the BP7006, BP7004 or BP10B.
