The Klipsch RP-1200SW is a 12-inch powered subwoofer from the Reference Premiere II line, built for home theater and music systems that need deep, high-output bass. A front-firing Cerametallic woofer and Class D amplifier with an analog preamp stage give it rated extension to 16.5 Hz and up to 121 dB of output. A front-firing Aerofoil slot port keeps the cabinet placement-friendly, and dual RCA/LFE inputs, low-pass and 0/180° phase controls, plus an optional WA-2 wireless kit make setup flexible. It sits above smaller 10-inch subs in output and depth, and rivals at this level trade some of that slam for a more compact box or app-based room correction.

Owners of the Reference Premiere subwoofers generally praise the output and depth for the size and the clean blending with Klipsch speakers. Common notes are the cabinet's bulk and the need to dial in placement and crossover.
