12-inch powered subwoofer for home audio

The Klipsch R-120SW is a single subwoofer designed to add deep low-frequency impact to a stereo or surround system. A 12-inch spun-copper IMG woofer driven by an all-digital amplifier produces bass down to 29 Hz for movies and music. It connects through line-level or LFE RCA jacks and fits in a black textured wood-grain vinyl cabinet.

400-watt peak power with 29 Hz low-end

The built-in amplifier delivers 200 watts continuous and 400 watts peak output, reaching a maximum acoustic level of 116 dB. Frequency response extends from 29 Hz to 120 Hz at +/- 3 dB, so the unit handles deep effects and musical fundamentals comfortably. Output drops below 29 Hz, and the single RCA input pair limits integration to receivers with a dedicated subwoofer pre-out.

Front-firing driver with crossover and phase

A front-mounted LED indicates power status while the rear panel provides gain, low-pass crossover and phase adjustments to blend the subwoofer with main speakers. The package includes a removable grille, a power cord and a manual. Wireless connectivity, room-correction software and additional input options are not included.

Questions about this item

Will the 12" spun-copper IMG woofer and 200W continuous amplifier overpower my existing bookshelf speakers?

The subwoofer handles only the 29Hz–120Hz range, so it supplements rather than competes with your main speakers. Use the gain and low-pass crossover controls to match its output level to the rest of your system.

How can I confirm the subwoofer is operating correctly after connecting it?

The front-mounted LED power indicator lights when the unit is on. Play low-frequency content; you should hear clean bass down to 29Hz with the woofer moving visibly and no audible distortion at the 116dB maximum acoustic output.

What accessories are included in the box and what must I supply myself?

The package contains the subwoofer, a removable grille, a power cord and the manual. You will need to provide a subwoofer cable with RCA plugs to connect the Line/LFE input to your receiver or processor.
