Klipsch SPL-120 Powered Subwoofer

Overview

The Klipsch SPL-120 is a 12-inch powered subwoofer built to deliver deep, high-output bass for both home theater and music. A front-firing 12-inch spun-copper Cerametallic long-throw woofer is driven by an all-digital Class D amplifier rated at 300 watts RMS and 600 watts peak, loaded in a bass-reflex enclosure with an internally flared front-firing slot port for clean, low-turbulence output. Frequency response reaches down to 24 Hz, and the amplifier panel offers variable low-pass crossover and phase controls plus line-level and LFE inputs.

Why This Model Matters

The SPL series sits at the top of Klipsch's powered-subwoofer range, and the SPL-120 brings genuine reference-grade slam to a manageable 12-inch footprint. Its copper-faced Cerametallic driver and front-firing port make it flexible about placement, and an optional wireless adapter (WA-2) lets it integrate without a hard-wired run to the receiver. It is offered in the US as a Crutchfield exclusive.
