Boston Acoustics PV500 Powered subwoofer

High-impact bass with silky smooth response — the PV500 powered sub from Boston Acoustics will breathe new life into your movies and music. Boston's state-of-the-art technology and design allow the PV500 to cleanly reproduce even the most challenging low-frequency passages. The 100-watt amp provides plenty of muscle, and the 10" down-firing woofer can move a lot of air. Get ready for dynamic bass with serious punch! The PV500's built-in amp includes Boston's proprietary BassTrac® circuitry, which keeps the bass rich and full while eliminating audible distortion. And the sub's solidly built cabinet features extensive internal bracings for resonace-free performance. A convenient volume control on the front of the unit lets you easily adjust the low-frequency output. You can hook up the PV500 to your receiver via the line-level or speaker-level inputs, and use the adjustable crossover for perfect blending with the rest of your speakers. There's even a dedicated LFE input, which bypasses the sub's crossover for home theater bass precision
