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 6B, 8B, 10B and 30 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 2000 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 unequalled 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 6B, 8B, 10B and 30 radiate the full sonic spectrum both forward and rearward in an omni-directional pattern much like sound is produced in real life.

The benefits 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!

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 6B, 8B, 10B and 30 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 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 BP 10B and 30, like the BP2000 and 2002, also include an additional divider/brace panel separating the front and rear drivers.

Computer Synthesized Transmission Line Tuning (CSTL T)

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.
