Product Details

Definitve Technology Bipolar Floor Standing Speaker - BP10BK

Definitive Technology's BP 10B, 8B, and 6B are revolutionary audiophile engineered, designer styled loudspeakers intended for musical reproduction and home theater systems of the highest quality (including Dolby Pro-Logic*, Dolby Digital AC-3* and DTS*).

These full-range bipolar (front and rear) radiating systems combine the lush spacious soundstaging, lifelike depth-of-field, razor-sharp resolution and pinpoint imaging of the finest dipolar panel loudspeakers with the extended bass response, high-efficiency, wide dynamic range and easy-to-position convenience of the best conventional box systems.

Audiophile Performance, Designer Styling, and Unmatched Value

The goal of the Definitive design team was to create state-of-the-art loudspeakers which offered unsurpassed sophisticated technology and lifelike musical and cinematic reproduction combined in sleek and stylish designs which could be easily and attractively placed in your home environment. Their success in achieving these goals is immediately apparent when you listen to your favorite music or movie through Definitive speakers. The elegant slender towers seem to disappear in a huge natural soundstage which extends in a three-dimensional arc beyond the speakers from left to right, and exhibits front to back depth which, at times, can be almost startling in its ability to recreate the illusion of live music or cinematic action being performed in your room (which will seem to be almost magically expanded in size).

Thousands of man-hours of critical listening, design processes utilizing the most advanced computer loudspeaker development programs available and proprietary engineering investigations at the NRC (the world's most advanced loudspeaker research facility) have combined to produce loudspeakers like no other in the world. The spectacular three-dimensional imaging, awesome deep bass response and silky smooth high definition linearity of the Definitive Technology BP 10B, 8B, and 6B are the result of the utilization and integration of a myriad of technological advancements and breakthroughs (including the latest state-of-the-art components and technology developed for our flagship BP 3000 Series loudspeakers) which have been combined to create unmatched instruments for the reproduction of music or movies in your home. They truly recreate reality that totally suspends disbelief.

The Sonic Superiority of Definitive's Bipolar Loudspeakers

Experts agree that bipolar loudspeakers are unquestionably superior for both music and home theater and Definitive is the leader in bipolar technology. What is responsible for the unequaled sonic performance of Definitive's bipolar speakers? Quite simply, each speaker incorporates two complete sets of drivers-one facing forward and the other facing to the rear. Thus, the BP 10B, 8B, and 6B radiate the full sonic spectrum both forward and rearward in an omni-directional pattern much like sound is produced in real life.

The audible benefits you will hear are dramatic! This unique technology provides you with a lifelike balance of early-arrival sound information (which provides focus, clarity and location data), and properly delayed late-arrival information (which conveys the lush three-dimensional soundstage of a live music or cinematic performance). In addition, the special driver topology, as well as wide dispersion, assures a superb panorama of lifelike sound for every listener in your room wherever they sit or stand. Most importantly, however, Definitive's bipolar speakers make the walls of your room seem to disappear and, in effect, expand the size of your room into the soundspace of the live event your system is reproducing. They literally bring your music and movies to life!

Computer Synthesized Transmission-Line Tuning (CSTLT)

Transmission-line loading of low frequency drivers has long been acknowledged among critical audiophiles as producing the deepest, cleanest and most uncolored bass response. The construction of a true and properly engineered transmission line is, however, an extremely complex and expensive procedure. Definitive Technology's engineers have developed, with the aid of a supercomputer at a major Eastern university, a new bass tuning program which basically duplicates the loading of a transmission line (in terms of extended bass response and ideal transient behavior) in a much more elegant and cost-effective cabinet construction.

Monocoque, Non-Resonant, Low-Diffraction Cabinets

The cabinet of a loudspeaker plays a large part in its sonic performance. Diffraction, or the secondary radiation of sound caused by cabinet edges, grill frames and other protrusions, can color the sound of a loudspeaker. The design of the BP 10B, 8B, and 6B reduces diffraction to an absolute minimum by flush mounting drivers on extremely narrow baffles with radiused edges, which are covered by a frameless grill "sock."

In addition, the resonant vibration of a loudspeaker's cabinet walls and baffles can also impart unwanted coloration. The Definitives' monocoque cabinets are constructed of high-density medite with l " thick front and rear baffles, foam dampening pads and internal braces. This virtually eliminates resonant cabinet coloration which could otherwise interfere with the pure sound produced by our high definition drivers. The BP 10B, like the BP Power Towers, also include an additional divider/brace panel separating the front and rear drivers.

Multiple High-Definition Cast-Magnesium Basket Drivers

The BP 10B, and 8B all utilize multiple high definition cast basket bass/midrange drivers (the same as used in our flagship BP3000 Series) for significant performance advantages in the areas of bass reproduction, lifelike midrange clarity and dynamic range. These sophisticated bass/midrange drivers incorporate deeply drawn mineral-filled homopolymer cones, combined with butyl rubber surrounds and dustcaps, 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 bass response. In addition, they are assembled utilizing an aerodynamically designed, magnetically inert, cast-magnesium basket to minimize internal reflections off the back of the cone and preserve structural and magnetic integrity under all conditions. The BP 6B uses otherwise identical stamped basket versions of the BP 8B 's cast basket drivers

Moving Coil Pure Aluminum Dome Tweeters

The moving coil dome tweeters Definitive developed for the BP3000 Series are now incorporated in the BP 10B, 8B, and 6B. They utilize a specially annealed pure aluminum 25 mm dome, suspended by a silk surround and acoustically loaded by a precisely configured phase plug/lens, engineered to assure perfectly controlled, absolutely linear movement. This results in velvety smooth extended response (beyond 30 kHz), greatly reduced distortion, improved transient response, wider dispersion and notably higher definition. Magnetic fluid damping is incorporated for ultra high power handling.

Phase-Coherent Linkwitz-Riley Crossover Networks

The crossover network of a loudspeaker is the real heart of the system, as it is responsible for perfectly blending together the sound of the various drivers into a musically seamless whole. The sophisticated Linkwitz-Riley designs used in the BP 10B, 8B, and 6B equalize the drivers for linear phase and Frequency response. This preserves the phase coherence, transient response and dynamic integrity of the signal for absolutely lifelike music and home theater reproduction in your home.

Easily Positioned for Superior Sound Throughout Your Room for Every Listener

BP 10Bs, 8Bs, and 6Bs are engineered to be easy to position (just 4" to 24" out from the wall) in any listening room or home theater installation in order to achieve superb sonic reproduction throughout your room. In addition, a major benefit of the special driver topology is wide dispersion, which assures a superb panorama of lifelike sound for virtually every listener in a room, no matter where they sit or stand.

Considered one of the world's finest loudspeakers, the BP 10B, in the words of The Inner Ear Report, is "almost too good to be true!" Its combination of full-range bipolar technology, computer synthesized transmission line tuning (for sub-woofer-quality bass), monocoque low-diffraction cabinet and Definitive's high definition drivers (two 17 cm cast-magnesium basket bass/midrange drivers and two 25 mm pure aluminum dome tweeters) results in a true state-of-the-art speaker of unsurpassed quality and value. It utilizes larger drivers than the BP 8B for even fuller, more extended bass response, higher power handling and greater dynamic range.
