Multiple High Definition Cast-Magnesium Basket Drivers
The BP 8B, 10B and 30 all utilize multiple high definition cast basket bass/midrange drivers (the same as used in our flagship BP 2000 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 tempera- ture vented voice coils and massive magnet structures. This combination of features assures high definition, superb transient response, high efficiency, high power handling and extend- ed 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 BP2000 Series are now incorporated in the BP 6B, 8B, 10B and 30. They utilize a specially annealed pure alu- minum 25 mm dome, suspended by a silk surround and acoustically loaded by a pre- cisely 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 6B, 8B, 10B and 30 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 Superb Sound Throughout Your Room
BP 6Bs, 8Bs, 10Bs and 30s are engineered to be easy to position (just 5" 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 life- like sound for virtually every listener in a room, no matter where they sit or stand.
There’s a Superb Definitive Bipolar Tower Perfect for You
The BP 6B: Leading experts agree that Definitive’s revolutionary bipolar loudspeak- ers are sonically superior to any conventional speaker regardless of size or price. Our least expensive tower, the astonishing BP 6B, brings all the dramatic benefits and sonic superiority of full-range bipolar technology to a new level of affordability.
The BP 8B: The BP 8B is an extraordinary full-range bipolar loudspeaker which offers award-winning sonic performance superior to competitors’ systems selling for twice its price and more. The BP 8B’s taller cabinet and cast basket drivers deliver even more extended bass response than the BP 6B. Its exquisite, jewel-like piano- gloss black or natural oak finish complements the finest home furnishings, and its sleek, ultra-compact design takes up only 1/2 sq. ft. of floor space.
The BP 10B: 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 defini- tion 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.
The BP 30: Definitive’s BP 30 utilizes all the technology incorporated in the BP 10B and combines it with virtual point source coincidentally radiating, symmetrical- ly concentric driver arrays. Each BP 30 incorporates four 17 cm bass/midrange drivers which are arrayed on the front and rear baffles in two concentric pairs, each surrounding a pure aluminum dome tweeter. Each pair of bass/midrange drivers creates a virtual point source radiating from a position midway between them, which is coincident with the tweeter location. This symmetrically concentric (or D’Appolito) point source mounting results in further improvements in the areas of driver blending, depth retrieval, lateral imaging and dispersion. Additionally, the use of four bass/midrange drivers extends the bass response below 20 Hz (superior to most subwoofers) with power handling capability exceeding 500 watts. The BP 30 incorporates provisions for bi-amping or bi-wiring.
I n 1972, Sandy Gross and two classmates from Johns Hopkins
University formed what was to become one of the world’s most successful loudspeaker manufacturers.
In 1988, Sandy left to pursue his ultimate dream and create truly world-class loudspeakers dramatically superior in design, technology, sonic performance, construction quality and value to everything which had come before.
Voted #1 for quality and reliability by top industry professionals in a nation- wide dealer survey, Definitive Technology loudspeakers are the suc- cessful realization
of this dream.
“In a word, the performance is stunning. These speak- ers have a huge advan- tage for home cinema.”
