Definitive Technology Bipolar Series SuperTower Floor-Standing Speakers - BP8080ST (Sold As Each)
A Legend Reborn
Definitive Technology’s first product in 1990 was a bipolar tower loudspeaker.
The BP10 was the first step in building the company that stands 20 years later
as the best selling and most honored brand of audiophile-grade loudspeakers
in the USA. Later Definitive pioneered the concept of “powered towers”
by incorporating powered subwoofers into Bipolar floor-standing speakers and
dubbed them “SuperTowers.” The BP-8080ST is a third generation BP
SuperTower and makes use of our most advanced technologies, including a new
patent-pending approach to bipolar speaker design called Forward Focused Bipolar
Array, Digital Signal Processing amplifier and our patented BDSS driver technology.
The BP-8080ST SuperTower is the crowning achievement of over 20 years of research
and development to create the perfect balance of style, convenience, and most
of all performance in a floor-standing loudspeaker.
The Most Advanced Technologies for the Most Advanced Performance
If you love great sound you must experience Definitive’s BP-8080ST Bipolar
SuperTower. Its combination of Forward Focused Bipolar Array™ technology
(for rich life-like, room-filling, three-dimensional sound), built-in SuperCube®
technology powered subwoofers (for lightning-fast, earthshaking bass), and our
latest generation patented Balanced Double Surround System (BDSS) midrange drivers,
all housed in a rock-solid attractive enclosure, delivers unsurpassed sonic
Bipolar Technology Brings Performances to Life in Your Home
Many experts and in-the-know listeners agree that bipolar speakers are superior
for both music and home theater. With bipolar speaker technology each speaker
incorporates two sets of drivers, one facing forward and the other facing to
the rear so that the speakers radiate sound both forward and rearward exactly
as sound is produced in real life. Forward Focused Bipolar Array™ technology
is Definitive’s patent-pending improvement to our original Bipolar designs.
This new ground-breaking technology combines the huge life-like imaging benefits
of bipolar design with improved pinpoint localization of soloists, greater placement
flexibility, and superior intelligibility.
The sonic benefits you hear are dramatic! This unique technology provides you
with a lifelike balance of early-arrival sound from the front facing drivers,
which provides focus, clarity and location data, and reflected delayed sound
from the rear drivers 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 for every listener in your
room. Most importantly, Definitive's bipolar speakers make the walls of your
room seem to disappear transporting you into the sound space of the recoded
event. 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!
The Subwoofer System Will Rock Your World
Each BP-8080ST combines a built-in 12" subwoofer driven by a 455-Watt class
D amplifier and two pressure-coupled 12-1/2" Low Bass radiators for 33%
more surface area than a single 18" woofer but with better control, speed
and detail than a single big woofer could ever deliver. The dual built-in powered
subwoofers achieve dramatically better blending, integration and timbre accuracy
than could ever be achieved with separate subs.
The brawny 455 Watt Class D amplifier features an integrated Digital Signal
Processor (DSP) – in essence a mini computer – that equalizes the
woofer system to extend and smooth the bass response, provides a phase coherent
crossover to perfectly blend the subwoofer system with the midrange arrays for
seamless high performance. Digital protection systems tightly monitor and control
the woofer system to prevent distortion and woofer damage at ultra-high volume
levels. The bottom line is the BP-8080ST’s bass will rock your world like
no other speaker anywhere near its price and size.
Why 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. Second, two subwoofers in the room reduce “standing wave”
room resonances that create bass dead zones in the room. With two ST-8080STs
you’ll enjoy high impact bass throughout the room.
Most importantly the subwoofers are perfectly integrated with the mid/high
section. Audiophiles often spend hours moving and adjusting their subwoofers’
crossover and phase controls in pursuit of perfect subwoofer to main speaker
“blending.” With the BP-8080ST you won’t have to go through that
kind of hassle to get great sound. Definitive’s engineers have perfectly
adjusted the crossover and phase 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 great sound.
Patented Technology Delivers High Definition Mids and Highs
Each BP-8080ST features a D’Appolito front array consisting of two cast-basket
5-1/4" second generation BDSS midrange drivers surrounding a 1" pure
aluminum dome tweeter housed in an acoustically isolated sealed enclosure. The
drivers feature Definitive’s patented Balanced Double Surround System (BDSS)
technology that supports the speaker cone at both the inner and outer edges
allowing longer, more linear excursion for greater clarity and finely textured
inner detail. A new patent pending Linear Response Waveguide™ smoothes
off-axis frequency response and disperses sound over a wider area for crystal
clear intelligibility for every listener in the room. The tweeter is a pure
aluminum dome, which has been heat-treated to relax the crystal structure and
then coated with a ceramic to produce extended highs that reveal nuance and
shimmer without a trace of edginess.
The rear array uses a single identical BDSS driver and the same 1" aluminum
dome tweeter as used in the front array. Like the front array the rear array
is housed in a separate sealed MDF enclosure to isolate the midrange drivers
from the woofers’ influence.
Slim Elegant Styling with Rambo-Like Brawn
All the driver and electronics technology in the world would be wasted if housed
in a resonance-prone box. We devoted as much Design and Engineering attention
to the styling and construction of the 8080’s enclosure as any other part
of its design.
The tapered front of the enclosure serves to make it appear slimmer while also
enhancing sound quality by minimizing cabinet diffraction distortion. The decorative
high gloss end cap and bottom panel add elegance to the matte black tower the
way satin piping adds dash to a tuxedo. Each BP-8080ST occupies a mere 1.4 square
feet of floor-space (including stabilizer feet) leaving plenty of room for furnishings.
But the enclosure’s most important job is to be totally inert and resonance
free so as not to color the sound. And that’s just we did in engineering
the BP enclosures. Wherever a driver is attached to the cabinet we placed a
second layer of heavy MDF (a low resonance wood composite material) to prevent
the drivers from imparting vibration to the rest of the enclosure. The sealed
midrange enclosures also serve to provide bracing for the side walls while MDF
cross braces near the woofer further stiffen the system. Tap on the side panels
of a BP enclosure to hear the solid “thud” of a solid, well-damped
cabinet instead of the hollow ring of a poorly constructed speaker. NOTE: the
high gloss polymer composite end cap is a decorative element; it is not part
of the acoustical system.
The Proof is in the Listening
This extraordinary speaker sets a new reference standard for high-accuracy loudspeakers
in its class and achieves equally superb performance with both music and movies.
The BP-8080ST reproduces a silky smooth, incredibly detailed sonic image at
lifelike volume levels with a sense of ease which is truly remarkable.
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 recreates the illusion of live music or cinematic action being performed
live in your room. This combination of high resolution, magnificent sound-staging
awesome bass and explosive impact envelops you in the ultimate listening experience.
Now that you’re thoroughly impressed with the technology and passion we’ve
poured into every BP series product it is time to find a stocking dealer near
you to audition this remarkable achievement of art and science.
