Klipsch R-121SW 12 Inch Front-Firing Powered Subwoofer 200W

The Klipsch R-121SW is a 12-inch powered subwoofer built to deliver deep, controlled bass for home theater, music, and gaming systems.

If your speakers sound clean but lack the low-end impact that makes movies feel cinematic and music feel full, the Klipsch R-121SW is a strong upgrade. Its 12-inch spun-copper TCP woofer and 200W all-digital amplifier are designed to produce powerful bass with low distortion, while the front-firing design makes placement easier in real living rooms and media spaces. With adjustable crossover and phase control, it integrates smoothly into a wide range of stereo and surround sound systems.
