    A Legend Reborn
    Definitive Technologya??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 a??powered towersa?? by incorporating powered subwoofers into Bipolar floor-standing speakers and dubbed them a??SuperTowers.a?? 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 Definitivea??s BP-8080ST Bipolar SuperTower. Its combination of Forward Focused Bipolar Arraya?? 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 performance.

    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 Arraya?? technology is Definitivea??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
    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) a?? in essence a mini computer a?? 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-8080STa??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 youa??ll have two subwoofers in the room instead of just one for simply more bass output. Second, two subwoofers in the room reduce a??standing wavea?? room resonances that create bass dead zones in the room. With two ST-8080STs youa??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 subwoofersa?? crossover and phase controls in pursuit of perfect subwoofer to main speaker a??blending.a?? With the BP-8080ST you wona??t have to go through that kind of hassle to get great sound. Definiitivea??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.

    The BP-8080's driver array
    pure aluminum dome tweeter housed in an acoustically isolated sealed enclosure. The drivers feature Definitivea??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 Waveguidea?? 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 woofersa?? 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 8080a??s enclosure as any other part of its design.

    The BP-8080's enclosure is solidly built
    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 enclosurea??s most important job is to be totally inert and resonance free so as not to color the sound. And thata??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 a??thuda?? 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.
