Bass for the front row and beyond
The 642eSB is a powered subwoofer for music and home theater systems. Its curved cabinet houses the bass driver and amplifier, giving the low-frequency channel a dedicated speaker of its own.
Use the level and crossover controls to blend it with the main speakers, or follow the receiver's bass-management settings. The subwoofer manual covers the connections and adjustments needed during setup.
