Maximize the bass response of your home theater by adding the Reference Premiere RP-1400SW 14" 1000W Subwoofer from Klipsch. It maximizes the low-end sound with a balanced construction that efficiently combines a 14" spun copper Cerametallic woofer, high-efficiency Class-D amplifier, and solid MDF cabinet. The result is 500W RMS (1000W peak) of rumbling power.
