The Klipsch R-1210SW is a high-output active subwoofer engineered to deliver deep, fast and room-filling bass for both home cinema and stereo systems. Featuring Klipsch’s advanced spun-copper Thermoformed Crystalline Polymer (TCP) woofer and a powerful all-digital amplifier, it combines extreme efficiency with precise low-frequency control.

🔊 Spun-Copper TCP Woofer Technology

The 12" high-excursion woofer uses Thermoformed Crystalline Polymer (TCP), a material that is exceptionally rigid and lightweight. This minimizes cone breakup and distortion while maintaining lightning-fast transient response. The result is bass that is deep, tight and highly accurate, even at high output levels.

⚡ High-Efficiency All-Digital Amplifier

The integrated all-digital amplifier delivers 200 watts of continuous power and up to 400 watts of peak power with excellent efficiency and control. This ensures strong dynamic headroom, fast response and low thermal stress for long-term reliability.

🎶 Sound Performance

The Klipsch R-1210SW produces authoritative, physical bass with outstanding speed and clarity. Explosions in movies hit hard and clean, while musical bass lines remain articulated and controlled. Its tuning offers an ideal balance between cinematic impact and audiophile precision.

🎛️ Precision Control & Integration

A variable low-pass crossover and 0/180° phase control allow seamless blending with your main speakers. The subwoofer features Line and LFE RCA inputs, ensuring universal compatibility with stereo amplifiers and AV receivers.
