Klipsch® KSW-10 Powered Subwoofer – 10" Woofer, Tested, Excellent Condition

Maker marked Klipsch KSW-10 Powered Subwoofer, a high-performance model from the Klipsch Synergy Series. Designed for deep, dynamic low-frequency response, the KSW-10 features a 10-inch fiber-composite woofer in a vented MDF cabinet, delivering precise bass ideal for home theater and music systems.

The control panel includes adjustable level and low-pass filter (40–120 Hz) dials, a phase switch (0°/180°), and a power selector (Off/Auto/On). Inputs include both RCA line-level/LFE and speaker-level binding posts, ensuring versatile system integration. The subwoofer’s front-ported design, down-firing woofer, and auto power function make it both powerful and efficient. Finished in matte black vinyl, this unit pairs well with a variety of speaker systems and was originally part of Klipsch’s acclaimed Synergy Series.
