Definitive Technology Floor-standing Bipolar Loudspeaker BP10B

Definitive Technology's BP10 is a revolutionary audiophile-engineered designer-styled loudspeaker intended for musical reproduction and home theater systems of the highest quality. This full-range bipolar (front and rear) radiating system combines 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.

Truly Divine Performance

When the pipe organ in New York's historic Trinity Church was damaged beyond repair by contaminants from the World Trade Center collapse, organ manufacturer Marshall & Ogletree was commissioned to replace the original with a state-of-the-art electronic organ that would sound exactly like a pipe organ. Sixty Definitive BP10B bipolar towers were chosen to replace the pipes (one for each organ pipe) to make what has been described as "the most ambitious digital organ currently in use anywhere." The organ's designers knew that only a bipolar loudspeaker could reproduce the spaciousness of a real pipe and concluded that the Definitives "were the easy winner."

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. 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 and design processes utilizing the most advanced computer loudspeaker development programs available along with fundamental research 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 BP8B are the result of a myriad of technological advancements and breakthroughs (including the latest state-of-the-art components and technology developed for Definitive's flagship BP7000 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

Many experts and in-the-know listeners agree that bipolar speakers are absolutely superior for both music and home theater. Each speaker incorporates two complete sets of drivers, one facing forward and the other facing to the rear. Thus, our bipolar speakers radiate the full

sonic spectrum both forward and rearward in an omni-directional pattern, exactly as sound is produced in real life.

The sonic benefits you 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. This combination creates a huge soundfield which is rich, warm, ultra clear and vibrantly alive. Bipolar technology assures a superb panorama of lifelike sound for every listener wherever they are in the room. 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 sound space of the recoded event your system is reproducing. They will literally bring your music and movies to life in your home. One listen and you can never go back to conventional speakers again!

Movies and music are reproduced with unequaled purity, transparency and lifelike realism. These elegant, slender towers seem to disappear in a huge natural soundstage which extends in a three-dimensional arc beyond the speakers with front to back depth which can be almost magical in its ability to recreate the illusion of live music or cinematic action actually being performed in your room. This combination of high resolution, magnificent sound-staging awesome bass and explosive impact literally envelops you in what is absolutely the ultimate listening experience.

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, grille frames and other protrusions, can color the sound of a loudspeaker. The design of the BP10B, BP8B, and BP6B reduces diffraction to an absolute minimum by flush mounting drivers on extremely narrow baffles with radial edges, which are covered by a frameless grille "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 1" 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 BP10B, like the BP SuperTowers, also include an additional divider/brace panel separating the front and rear drivers.

Multiple High-Definition Cast-Magnesium Basket Drivers

The BP10B utilizes multiple high definition cast basket bass/midrange drivers (the same as used in Definitive's flagship BP7000 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 polymer 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.

Moving Coil Pure Aluminum Dome Tweeters

The moving coil dome tweeters Definitive developed for the BP7000 Series are used in the BP10B. They utilize a specially annealed pure aluminum 1-inch 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 design used in the BP10B equalizes 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 BP10Bs 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 every listener in a room, no matter where they sit or stand.
