Great working subwoofer. I went with something smaller due to this one was too loud for my apartment. Comes with power cord and RCA cable. Details about it below. Enjoy rich, accurate bass with the PSW110 from Polk. Its 10" woofer and 100-watt high-current amplifier work together to produce powerful lows with your movies and music. And this subwoofer sports a new, more powerful driver design to deliver deeper, louder, and punchier bass than previous Polk subs. Special circuitry inside the amp and a solid MDF cabinet with internal bracings ensure clean, detailed lows, even when you crank up the volume.
