About the Definitive Technology BP-8080ST
Towering sound for movies and music
Towering sound for movies and music
Don't just watch your favorite movies, live them with the BP-8080ST, the flagship speaker in Definitive's Bipolar SuperTowerT line. This innovative speaker uses a unique driver design with both front- and rear-firing speaker arrays to surround you with rich, lifelike sound. A potent powered subwoofer built into the bottom of the cabinet delivers intense bass. Even in large rooms, you'll experience a huge, three-dimensional soundstage that pulls you into your music concerts and movies as if you were there. Plus, this speaker has attractive high-gloss black top and bottom caps with a cloth grille-wrapped enclosure, making it a sophisticated addition to your home theater setup.
Bipolar speaker technology brings your favorite recordings to life
Here's how it works: direct sound from the front two midrange drivers and tweeter arrives at your ears first, to provide clear, focused imaging. That's followed by sound from the rear mid and tweeter, which is slightly delayed, to enhance spaciousness. The combination creates a lush, seamless soundstage that's more like the way we hear sounds in real life. And thanks to Definitive's Balanced Double Surround System (BDSS) drivers, your music and surround effects will sound incredibly clear, allowing you to pinpoint the soloist in a band or the direction of a jaguar's call in the jungle.
Powerful bass built right into the cabinet
At the base of the speaker is a 12" side-firing subwoofer coupled to two passive radiators. This trio creates a total surface area greater than that of a traditional 18" woofer, but with better bass control, speed, and detail than a single huge woofer could achieve. A built-in 455-watt amplifier powers the subwoofer, delivering hard-hitting bass that eliminates the need for an external sub. And because a subwoofer is built into the cabinet, bass output is already perfectly blended with the mids and the highs. All you have to do is set the bass volume to match your room and taste, then sit back and enjoy your music and movie soundtracks.
Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality.

Bipolar Design: The Definitive Technology BP-8080ST is a 3rd generation "SuperTower." This bipolar speaker contains drivers on the front and rear of the cabinet. The BP-8080ST uses a new patent-pending design called Forward Focused Bipolar Array. By radiating sound both forward and rearward, the speaker produces sound as it is in real life, with improved pinpoint localization of soloists, greater placement flexibility, and superior intelligibility.
Non-Resonant Tapered Cabinet: The BP-8080ST features a highly-engineered inert and resonance-free heavy MDF (medium-density fiberboard) cabinet to prevent coloring the sound. The front of the enclosure is tapered to make it appear slimmer. Wherever a driver is attached to the cabinet, a second layer of MDF is attached to prevent the drivers from causing vibration to the rest of the enclosure. The sealed midrange enclosures serve as braces for the side walls, while MDF cross braces near the woofer further stiffen the cabinet. The entire enclosure is wrapped in a cloth "grille sock", while the high-gloss polymer composite end-cap and bottom panel add a touch of elegance.
High-Definition Drivers: The BP-8080ST utilizes two cast-basket 5-1/4" high-definition polymer composite midrange drivers surrounding a 1" annealed Pure Aluminum dome tweeter in a D'Appolito front array. On the rear, there is a single identical 5-1/4" driver and the same 1" aluminum dome tweeter as used in the front array. The front and rear arrays are housed in separately sealed MDF enclosures to isolate the midranges from the influence of the subwoofer. The drivers feature Definitive Technology's patented 2nd-generation Balanced Double Surround System (BDSS) that supports the speaker cone at both the inner and outer edges, allowing longer, more linear excursion over a wider area. A new patent-pending Linear Response Waveguide smoothes off-axis frequency response and disperses sound over a wider area.
Built-in Powered Subwoofer: The BP-8080ST is equipped with a long-excursion, side-firing 12" subwoofer, driven by a 455-watt Class D amplifier with an integrated Digital Signal Processor. The subwoofer is pressure-coupled with two 12" Low Bass Radiators. The combination of the active subwoofer and two bass radiators gives you 33% more surface area than a single 18" woofer, but with better control, speed, and detail. The benefits of a built-in subwoofer include:
- Eliminates the need for a separate subwoofer that takes up additional floor space.
- More bass output from two subwoofers, compared to one.
- Two subwoofers reduce standing wave room resonances and dead zones for more evenly distributed bass.
- The subwoofers are perfectly integrated and blended with the mids and highs, eliminating the crossover and phase controls of a separate subwoofer.
Subwoofer Volume: The level of the subwoofer (relative to the other drivers) can be adjusted using the rotary dial on the back panel of the speaker. Once the bass level is set, the overall volume of the speaker system can be controlled by the receiver/amplifier.
Auto Power: The BP-8080ST has a special circuit that automatically turns on the amplifier when a signal is fed to the speaker. The LED on the back panel will glow when a signal is sensed and the amplifier turns on. After the signal ceases, it may take up to an hour for the amplifier to turn off. When first powering up after being unplugged, the LED will flash for about 30 seconds while the firmware is loading.
Stabilizer Feet: The speaker comes with four stabilizer feet which attach to the bottom of the cabinet, two per side, with the supplied self-tapping screws. Each foot has a threaded insert to allow you to screw in the supplied carpet spikes or smooth floor glides, depending upon the type of floor they're being placed upon. Four additional threaded inserts are provided on the bottom panel in case you decide not to use the stabilizer feet. The spikes and glides add approximately 1" to the overall height of the speaker.
Placement: The BP-8080ST Bipolar speakers have a lot of flexibility when it comes to placement and positioning. It is recommended that the speakers be placed at least 4" from a back wall, and at least 6" from a side wall. When used as left and right main speakers, you should set up the speakers and the listening position in an equilateral triangle, with the speaker cabinets turned slightly inward.
Binding Posts: The BP-8080ST is equipped with a pair of gold-plated, 5-way binding posts on the back of the cabinet to attach your receiver's speaker wire. The terminals will accept bare wire, pin connectors, spade lugs, single and dual banana plugs. Recommended amplifier power: 20 to 400 watts RMS.
LFE Input: For the powered subwoofer, the BP-8080ST has a single RCA LFE (low-frequency effects) input. Since you'll be using two speakers, you will need a Y-adapter to split the LFE output from your receiver to each subwoofer.
Wiring Options/Speaker Setup: You can connect the BP-8080ST in one of two ways, with or without the LFE connection. If you use only speaker wire, you should set the speaker setup on the receiver to "Large" and Sub to "No." If you connect the speaker with speaker wire and the LFE, the speaker setup should be "Large" and "Yes."
Note: It is recommended that you do not use the receiver's auto setup function, as it is often ineffective in setting up and adjusting speakers with built-in subwoofers.
AC Power: The speaker has an AC power input (IEC 2-prong type) on the back panel for plugging in the powered subwoofer. A 7' AC power cord is included.
