Definitive
Technology's BP10B, BP8B, and BP6B 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
BP10B, BP8B,
and BP6B
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 BP3000 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 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 BP10B, BP8B, and BP6B 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!
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.

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
BP10B, BP8B, and BP6B 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 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, and BP8B 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 BP6B uses otherwise identical stamped
basket versions of the BP8B's cast basket drivers
Moving Coil Pure Aluminum
Dome Tweeters
The moving coil dome tweeters Definitive developed
for the BP3000 Series are now incorporated in the BP10B,
BP8B, and BP6B. 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.

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 BP10B, BP8B, and BP6B 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 Superior
Sound
Throughout Your Room for Every Listener
BP10Bs, BP8Bs, and BP6Bs 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.
