Definitive Technology BP6B are the entry-level model Definitive Technology's Bipolar Tower line of floor-standing speakers that retail for about $400 per speaker. Unlike most of its competitors, the BP6B is a bipolar speaker, meaning that they have speaker drivers facing both to the front and the rear in the same phase creating a more broad soundstage as sound is reflected off of walls and is difficult to pinpoint where it's coming from. Unlike dipolar speakers, which feature drivers that are in reverse phase, that create a cancellation pattern, bipolar speakers actually create a bass boost from the constructive interference patterns. The bipolar design is often cited as a better speaker for movies than music, because if it's inherent surround sound bipolar operation.
