Product Details

Definitive Technology Rear BiPole Speaker - BPXBK

Definitive offers five compact Dolby AC-3* ready bipolar rear/side surround speakers (BP1.2X, BP2X, BPX, BPVX, and BPVX/P) intended for on-wall, shelf or stand mounting (you can also use any of our bipolar towers for rear/side surrounds) plus an in-wall bipolar surround speaker, the UIW BP/A). Like our center channels, they are built to the same high construction and performance standards as our 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 diffractionless grill/baffle interfaces.

The Bipolar Advantage

Definitives's bipolar surround speakers are simply the best available. Each is a true bipolar system containing two complete full-range speaker system, one on each side of the cabinet. Bipolar technology is absolutely superior for surround speakers because it synergistically combines the performance advantages of direct radiating (imaging, focus, localization, and specificity) and dipolar speakers (spacious, sourceless, all-enveloping ambience) into one ideal system which is perfect for all discret 5.1 formats including Dolby Digital AC-3*, DTS* as well as the new Dolby EX* and Dolby Pro-Logic*. They are all full-range, extremely linear, low-distortion systems which are timbre-matched to blend perfectly with all our speakers as well as other high-quality speaker systems. The Definitive bipolar rear speakers all have tremendous dynamic range as well as true high-definition sound quality which, combined with their bipolar radiation pattern, results in total immersion in the sound field. Home Theater's Brent Butterworth says, "they're actually better then dipoles for use with Dolby AC3* digital surround systems." Video Magazine raved: "They make all the difference in the 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."

In addition to their use as side/rear surround speakers, all are ideal for use as front effects speakers. Also, because Definitive's bipolar surround speakers are engineered as true high quality speaker systems, they are perfect for use as left and right front speakers with or without a subwoofer. Like Definitive's bipolar towers, all reproduce a huge, lifelike, exceptionally wide three-dimensional soundstage with absolutely stunning depth-of-field.

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 if desired. Positioning is extremely non-critical; unlike dipolar surrounds, which are limited by their specific sidewall placement placement requirements, Definitive's bipolars may be located on the sides or rear of the room (or both as in Dolby EX 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.

    Comments about Definitive Technology Rear BiPole Black Single Speaker:

    These speakers are something special indeed. Excellent build quality, extremely solid speaker. I bought a pair of these about 1 year ago and I can honestly say I am completely blown away by them each time they are put to use. I will tell you however, these speakers require power, and lots of it. With a 350 watt max rating, these speakers can take as much power as you can throw at them. Don't bother with AVR power as over 90% of them are falsely rated in terms of Watts per Channel. Use a dedicated power amplifier capable of at least 200 watts. This will give these speakers the type of reserve power that they will require to really open up and sing. Remember, you will much more easily damage your speakers by not giving them enough power and playing them at high volumes than putting more power than the speaker is rated for and playing at high volumes. Basically it eradicates the possibility of driver clipping and enables your speakers to play to the fullest of their ability. This way, if the speaker is damaged, it is because you physically pushed them past what the speaker itself can handle. (Excess of 105-110 dB which is ear damagingly loud) The BPX's Bipolar design is part of what makes these speakers special. Due to the driver array it is like getting (2) direct radiating speakers ( with a D
