The active E 110 Sub A subwoofer is designed to deliver high sound pressure levels. Small yet powerful, the high-performance 10″ woofer fits into a very compact housing and supplies a solid, low-ranging bass foundation. The integrated amp module delivers 600 watts at 4 ohms, and packs power enough to drive a pair of E 435s or a single E835. All connectors and control features for connected modules are located on the rear panel.
