Each BP Series speaker incorporates two complete sets of drivers-one facing forward and the other facing to the rear. Definitive's Bipolar models radiate the full sonic spectrum both forward and rearward in an omni-directional pattern much like sound is produced in real life. The benefits of Bipolar speakers include a huge three dimensional soundstage for every listener in the room. You don't have to sit in a confined â€œsweet spotâ€? to enjoy life-like sound quality.
