Boasting a modern design, the BP9000 Series utilizes a Bipolar Array to create immersive, room-filling sound. With Bipolar speaker technology, each speaker incorporates two sets of drivers, one facing forward and the other facing to the rear so that the speakers radiate sound both forward and rearward exactly as sound is produced in real life. The front array ensures precise imaging while the rear array delivers spaciousness and a massive, lifelike sound stage.
