product description

Big impact with a classic look

Klipsch is at it again with their latest line of Reference speakers, coupling classic design sensibility with the excellent performance they're known for. The 12" R-121SW subwoofer gives you powerful, controlled bass output that'll liven up your favorite movies and music. This sub works perfectly with the rest of the Reference lineup, but it'll rock in almost any system.

An efficient and precise woofer

The sub's built-in 200-watt digital amplifier, reinforced enclosure, and expertly crafted woofer cone keep its bass reproduction true to the original recording. The copper-spun TCP (Thermoformed Crystalline Polymer) cone is light but rigid, giving you deep low-frequency extension with minimal cone breakup and degradation.

Keeping it simple

It's easy to integrate the R-121SW into your system. A line-level stereo RCA/LFE input lets you connect to most stereo or home theater receivers. And back-panel crossover, auto switching, and phase controls help you dial in the sub to match the room and the rest of your setup.
