radiators
for an astounding 461.6 square inches of bass radiating area per
speaker! That’s 10% more area than a single 24-inch woofer but with
better control, speed and detail than a single big woofer could ever
deliver. The low-frequency performance sets new standards for speakers
priced under $50,000 a pair, with bass extension to 11 Hz, extremely
low distortion and tight transient response. A pair of BP7000SCs goes
lower than and has the bass impact and output level capability of seven
SuperCube® I subwoofers combined. The dual built-in powered subwoofers
achieve dramatically better blending, integration and timbre accuracy
than could ever be achieved with separate subs.
Each BP7000SC features bipolar D’Appolito front and rear mounted driver
arrays each consisting of two high-definition cast-basket 6-1/2"
bass/midrange drivers surrounding a 1" annealed Pure Aluminum dome
tweeter. Linkwitz-Riley crossover networks do a superlative job of
seamlessly blending the drivers for totally homogeneous sonic output as
if radiating from a full-range pulsating sphere.
This extraordinary speaker sets a new reference standard for
ultra-dynamic high-accuracy loudspeakers and achieves equally superb
performance with both music and movies. They will reproduce a silky
smooth, incredibly detailed wall-to-wall, floor-to-ceiling sonic image
with superb dimensionality at lifelike volume levels with a sense of
ease which is truly remarkable. As with all Definitive’s bipolar
speakers, they have an almost magical ability to recreate a stunningly
realistic holographic sound field. The elegant styling features
beautiful sculptural refinements to Definitive’s signature look with a
classic piano-gloss black finish.

speakers?
Each speaker incorporates two complete sets of drivers, one facing
forward and the other facing to the rear. Thus, our bipolar speakers
radiate the full sonic spectrum both forward and rearward in an
omni-directional pattern, exactly as sound is produced in real life.
The sonic benefits you 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.
This combination creates a huge soundfield which is rich, warm, ultra
clear and vibrantly alive. Bipolar technology 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 sound space of the recoded event your system
is reproducing. They will literally bring your music and movies to life
in your home. One listen and you can never go back to conventional
speakers again!
Movies and music are reproduced with unequaled purity, transparency and
lifelike realism. These elegant, slender towers seem to disappear in a
huge natural soundstage which extends in a three-dimensional arc beyond
the speakers with front to back depth which can be almost magical in
its ability to recreate the illusion of live music or cinematic action
actually being performed in your room. This combination of high
resolution, magnificent soundstaging, awesome bass and explosive impact
literally envelops you in what is absolutely the ultimate listening
experience.
Why High-Definition Built-In Powered Subwoofers
Are Better Than Separate Subs
Besides eliminating the need for a floor space-hogging separate
subwoofer, integrated subs offer dramatic performance benefits. First
is the obvious benefit that you’ll have two subwoofers in the room
instead of just one for simply more bass output. Most importantly the
subwoofers are perfectly integrated with the mid/high section.
Audiophiles often spend dozens of hours moving and adjusting their
subwoofers’ crossover and phasing controls in pursuit of perfect
subwoofer to main speaker “blending.” With the BP7000SC you won’t have
to go through that kind of hassle to get audio perfection. Definitive’s
engineers have perfectly adjusted the crossover and phase between the
subwoofer and main speaker sections to achieve seamless blending and
life-like sound. All you have to do is set the bass volume to match
your room and taste then sit back and enjoy audio perfection.
Home Theater Magazine agrees, "... it's a concept we heartily endorse
... integrated subwoofers are actually better than a separate
subwoofer. First of all, you always have two of them and using two
subwoofers helps minimize the detrimental effects of room modes, so you
typically get smoother response than you would get with a single
separate sub... Second, there is really no downside to using the
speaker cabinet for the subwoofer ... Third, and most important, the
interface between the subwoofer and the rest of the speaker is designed
by the manufacturer and optimized for the drivers and cabinet used in
the speaker [for] a nearly perfect blend between the subwoofer and the
rest of the speaker." The result is a combination of delicate
musicality plus thunderous power which allows you to experience truly
awe-inspiring deep rich bass response effortlessly extending down into
the range of purely physical subsonic energy that shakes the body and
stirs the soul.
Narrow Monocoque, Non-Resonant, Low-Diffraction Cabinets Maintain Sonic Purity
The cabinet of a loudspeaker plays a large part in its sonic
performance. We are often asked if our attractive, slim cabinets are
designed that way for styling or for performance reasons-and the answer
is, "Yes, both." Narrow cabinets dramatically improve three-dimensional
imaging. In addition, diffraction, or the secondary radiation of sound
caused by cabinet edges, grille frames and other protrusions, can color
the sound of a loudspeaker and impart a “boxy” coloration. The design
of our bipolar SuperTowers reduces diffraction to an absolute minimum
by flush mounting drivers on extremely narrow baffles with radial edges
covered by a frameless grille "sock."
The resonant vibration of a loudspeaker's cabinet walls and baffles can
also impart coloration. The tri-chambered monocoque cabinets of all
Definitive SuperTowers are constructed of extremely thick, dense medite
with foam damping pads and extensive internal bracing. This virtually
eliminates cabinet vibrations and resonance which would otherwise
interfere with the pure sound produced by Definitive's high-definition
drivers.
Definitive's High-Definition Die-Cast
Basket Drivers are an Engineering Marvel
All the bipolar SuperTowers utilize multiple arrays of
Definitive-developed magnetically shielded high-definition cast-basket
bass/midrange drivers for significant performance advantages in the
areas of upper bass reproduction, lifelike midrange clarity and dynamic
range. These sophisticated drivers are engineering marvels which
incorporate deeply drawn mineral-filled polymer cones, combined with
butyl rubber dust caps and surrounds, 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 linear response. In addition, the
aerodynamically designed, non-resonant, cast-magnesium baskets minimize
reflections of the sound radiating from the back of the cones and
preserve structural and magnetic integrity.
Definitive's Moving-Coil Pure Aluminum Dome Tweeters
The accuracy of high frequency reproduction really sets apart a great
loudspeaker. The magnetic fluid-cooled moving-coil pure aluminum dome
tweeters Definitive developed for the bipolar SuperTowers are of a
unique design that synergistically brings together the performance
advantages of metal domes (greater clarity) and soft domes (smoother
sound and better dampening) in one state-of-the-art tweeter design.
The pure aluminum dome is specially annealed (to "relax" the crystal
structure) and acoustically loaded by a precisely configured acoustic
phase plug/lens (to assure perfectly controlled, absolutely linear
movement). The tweeter’s voice coil sits in ferro-magnetic colloidal
fluid which serves to cool the voice coil for exceptional power
handling and also damps the system for smoother response and sonic
accuracy. In addition, the unique silk surround provides better
dampening and wave termination. The audible benefits of all this highly
advanced engineering include velvety smooth extended high frequency
response (beyond 30 kHz), greatly reduced distortion, improved
transient response, notably higher definition and crystal clear
life-like clarity.
Symmetrically Concentric D'Appolito Focused Field Driver
Arrays for Improved Wave Propagation
The BP7000SC incorporates four upper bass/midrange drivers which are
arrayed on the front and rear baffles in two concentric pairs, each
pair surrounding a tweeter. The tweeter acts as though it were mounted,
in effect, right in the center of one large driver. This symmetrically
concentric (or D'Appolito) point source mounting results in more
coherent wave propagation with further improvements in the areas of
driver blending, depth retrieval, lateral imaging and dispersion. In
addition, the early arrival soundfield is focused away from the floor
and ceiling and directly at the listener for even greater clarity.
Phase-Coherent Crossovers for Perfect Driver Blending
The crossover network of a loudspeaker is the real heart of the system.
It is like the conductor of an orchestra, telling each driver exactly
when to come in and precisely how loudly to play. Here Definitive's
talented engineers really work their magic, perfectly blending the
sound of the various drivers into a sonically seamless, musically and
cinematically coherent whole. Our complex and sophisticated
Linkwitz-Riley designs, which utilize the finest components, are
masterpieces of electrical engineering. They are differential
crossovers which equalize the front and rear drivers separately for
both linear frequency and phase response of their summed output. Also
included are advanced technology Zobel Networks which provide a more
stable load for your amplifier. This makes the speaker easier to drive,
which results in smooth, more natural sound. In addition, the
electronic crossovers in the subwoofer modules work together with the
Linkwitz-Riley networks to perfectly blend the subwoofers with the
bipolar arrays. The result is a symphony of sonic perfection that
completely preserves the phase coherence, transient response and
dynamic integrity of the original signal.
User-Friendly Bipolar SuperTowers Will
Sound Perfect in Your Home
Definitive SuperTowers are easy to hook up to your system, simple to
place and flexible in terms of room positioning. They are engineered to
be located as close as 4" or as far from the wall as you would like.
The mirror-imaged side-mounted subwoofers can face either toward or
away from each other for even greater flexibility and room tuning
ability. The bipolar SuperTowers are very efficient which allows them
to be used with virtually any receiver or amplifier and are of such
high quality that they allow you to appreciate all the subtle
excellence of the world's finest electronics. Since the subwoofers are
powered, the speakers are that much easier amplifiers to drive so you
are not forced to spend a huge amount for ultra high power electronics
to get superb, high output, high definition sound.
You can hook them up and achieve exceptional performance as simply as
running one set of speaker wires from your amplifier or receiver. And
for ultimate performance, you can bi-wire the mid- and high-frequency
section of BP7000SC. Finally, you can separately adjust the powered
subwoofers to compensate for room acoustics and speaker placement as
well as to achieve your personal sonic preferences.
