Maximize the bass response of your home theater by adding the Reference Premiere RP-1000SW 10" 600W Subwoofer from Klipsch. It maximizes the low-end sound with a balanced construction that efficiently combines a 10" spun copper Cerametallic woofer, high-efficiency Class-D amplifier, and solid MDF cabinet. The result is 300W RMS (600W peak) of rumbling power.
