Klipsch R-120SW 12" Subwoofer 200W 400W Peak 29-120Hz Black 2018

Klipsch R-120SW Subwoofer

The Klipsch R-120SW is a powered subwoofer built for home audio and home-theatre systems that need deeper bass extension. It uses a 12-inch spun-copper IMG woofer driven by an all-digital amplifier rated at 200 watts continuous and 400 watts peak. The bass-reflex enclosure tunes low-frequency output down to 29 Hz with a maximum acoustic output of 116 dB. This unit suits listeners who want authoritative low-end for movies and music in a residential setting.

Check Your Receiver Connections

Before ordering, confirm that your AV receiver or processor provides a line-level or LFE RCA output to feed the subwoofer. The R-120SW accepts only RCA inputs, so systems with only speaker-level subwoofer outputs will require an adapter or a different integration method. Verify that you have a nearby AC mains socket for the built-in power supply. The cabinet measures 14.0 inches wide, 19.20 inches deep and 16.50 inches high, so ensure the intended placement area accommodates those dimensions.

Build Quality and Daily Use

The enclosure is constructed from MDF and wrapped in a black textured wood-grain vinyl finish that resists minor scuffs. A rear-firing port handles bass-reflex loading, so leave a small gap behind the cabinet to avoid port noise or boundary reinforcement. On the rear panel you will find volume, low-pass filter and 0/180-degree phase controls for blending with main speakers, plus an auto power-on circuit that wakes the amplifier when signal is detected. No remote control is included, so adjustments are made manually at the subwoofer.
