Q4

What subwoofers do you recommend to use for the BP9000 series?

Since all BP speakers have active subwoofers integrated, there may be no need for installing a separate subwoofer in your home theatre. Anyhow, for low frequency effects and especially in larger rooms, it may good to add one, two or even four subwoofers of the Supercube series (Supercube 2000, 6000 or 8000) depending on the room size. If your AV receiver does not have enough Subwoofer outputs, please use an Y cable.
