Definitive
Technology's BP10B, 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.
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.
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!
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.
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.
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
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.
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.
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.
