Technology’s
BP 6B,8B, 10B
and 30 are revolutionary
new 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 cine-
matic 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 advance-
ments and breakthroughs (including the latest state-of-the-art components and tech-
nology 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 fac-
ing to the rear. Thus, the BP 6B, 8B, 10B and 30 radiate the full sonic spectrum both for-
ward 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 loca-
tion 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 impor-
tantly, 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 pro-
trusions, 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 baf-
fles 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 (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.
“Does a brilliant job of
reproducing both movie
soundtracks and musical
performances.”
