An unusual loudspeaker that offers exceptional performance for its size and price. The BP10 is a slender columnar speaker measuring 42" high, 9" wide, and 11-1/2" deep and weighing about 60 pounds. Its exterior is completely black, and the four sides are covered by a fabric sleeve that fits snugly around the enclosure. The wood base and top plate have a glossy lacquer finish.

The BP10 is a bipolar system (hence the "BP" designation) containing a pair of identical two-way speakers. One faces forward conventionally, and the other is on the rear panel, facing backward. Each consists of a 6-1/2-inch woofer and a 1-inch dome tweeter. The two woofers share a common enclosure vented by a single ducted port at the bottom of the rear panel. The designers chose a fourth-order Linkwitz-Riley network to give the BP 10 uniform response in the crossover region as well as optimum phase and transient response.

The BP 10 uses rugged, high-quality drivers. The woofers have cast-magnesium baskets, mineral-filled homopolymer cones with butyl rubber surrounds and dustcaps, high-temperature voice coils, and massive magnet structures. The fabric-dome tweeters have dual air chambers, one behind the dome and the other, connected to the first chamber by a hole through the pole piece, behind the magnet structure. Definitive Technology says that the dual chambers lower the tweeter's resonance frequency, extend its frequency response, and reduce distortion. An aluminum voice coil, high-temperature wire, and ferro-fluid damping enhance the tweeter's power-handling ability.

The BP10 has a rated frequency response of 20 to 28,000 Hz. It is recommended for use with amplifiers rated between 20 and 300 watts per channel.
