JBL L10cs Classic Series Powered Subwoofer

A 250 W with 10″” down-firing polycellulose woofer, bass-reflex cabinet with rear-firing ports

The JBL L10cs is a compact Classic Series subwoofer built around a 10″” down-firing polycellulose cone in a bass-reflex enclosure finished in real wood veneer. The cabinet is available in Natural Walnut or Black Walnut to match Classic Series loudspeakers and blend cleanly into a wide range of rooms.

An advanced built-in amplifier delivers 250 W RMS (500 W dynamic), giving the L10cs the headroom to add depth and scale to two-channel systems, integrated music setups, and home theaters. A variable low-pass network (50 Hz–150 Hz, 24 dB/octave) and a phase switch help you dial in seamless handoff to your main speakers.

Connection is kept straightforward with a mono RCA/LFE input. Day-to-day use is simple thanks to auto on/off, output-level and crossover controls, and a rear panel laid out for quick setup.
