Definitive Technology Bipolar SuperTowers BP 7004

Definitive Technology 7-Driver Bipolar SuperTowers with powered 10″ Subwoofers

Experience exceptional sound from this ingenious pair of speakers

The Bipolar SuperTower™ series combines bipolar speaker design with Definitive’s SuperCube® subwoofer technology to give you spacious, lifelike sound and rumbling bass. The BP7004 bipolar speaker uses both front- and rear-firing driver arrays to radiate full-range sound in all directions. Even in large rooms, every listener will experience a huge, three-dimensional soundstage with both music and movies.

Innovative bipolar design produces an exceptionally wide, deep soundstage

Each driver array in the BP7004 consists of one 5-1/4″ midrange paired with a 1″ dome tweeter. This bipolar design means that direct sound from the front drivers arrives at your ears first, to provide clear, focused imaging. That’s followed by sound from the rear drivers, 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.

Powerful bass built right into each cabinet

At the base of each speaker is a 10″ side-firing subwoofer coupled to two 10″ bass radiators. This trio creates a total surface area that’s almost as much as a traditional 18″ woofer, but has better bass control, speed, and detail than a single huge woofer could achieve. A built-in 300-watt amplifier powers the subwoofer, delivering massive bass that eliminates the need for an external sub. And because a subwoofer is built into each cabinet, bass output is already perfectly blended with the mids and the highs. So with a pair of BP7004s, you get two subs in your setup instead of just one.

Room-friendly sound allows flexible placement

The BP7004’s slim cabinet takes up less than a square foot of floor space, yet its bipolar design produces twice as much sound in your room as a conventional speaker. A sophisticated crossover equalizes the front and rear drivers separately for more precise control of their combined output. The bipolar driver arrays are wired together internally, so you connect the BP7004s to your receiver as you would conventional speakers, using one set of wires per speaker.
