Definitive Technology Bipolar Series SuperTower Floor-Standing Speakers -
BP8020ST
A Legend Reborn
Definitive Technology’s first product in 1990 was a bipolar tower loudspeaker,
the successful first step in building the company that stands 20 years later
as the best selling and most honored brand of premium 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-8020ST is a third generation BP SuperTower and makes use of many of our
most advanced technologies, including a new patent-pending approach to bipolar
speaker design called Forward Focused Bipolar Array. The BP-8020ST SuperTower
is the result 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.
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-8020ST combines a built-in long excursion 8" subwoofer driven by
a 150-Watt Class D amplifier and vented via a critically tuned, wide cross sectional
area slot bass vent. The slot shape and wide mouth area of the vent minimize
air turbulence for cleaner, deeper, and more efficient bass. The brawny amplifier
features protection systems to tightly monitor and control the woofer system
to prevent bad noises and woofer damage at high volume levels. The bottom line
is the BP-8020ST’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-8020STs
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-8020ST 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.
High Definition Mids and Highs
The BP-8020ST features a D’Appolito front array consisting of two 3-1/2"
The BP-8020's driver array
midrange drivers surrounding a 1" annealed Pure Aluminum dome tweeter housed
in an acoustically isolated sealed enclosure. 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 driver 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 8020’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-8020ST occupies a
mere 1 square foot 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-8020ST 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.
