Looking for the right combination of features in a subwoofer? Well, here's where big bass, great looksp, and an affordable price come together! Polk's PSW303 boasts a 100-watt high-current amp, powering an 8" driver with a bass-friendly Hi-Roll Surround. This rounded foam surround allows longer driver excursion than on most subs, so a lot of air gets moved. The result? Tons of sound! Also contributing to the quantity and quality of your lows is the PSW303's slot-loaded enclosure. By reducing port turbulence and distortion, the Slot Load Vent lets you hear bass that's dramatically full, yet impressively accurate. Other nice touches include this sub's extremely solid, yet compact, build, as well as its silver details and real wood veneer. The unfiltered LFE input, for maintaining 5.1 bass precision, is just another bonus. Bottom line? You've got the power you need for home theater, the precision you want in music, and a price that even the budget-minded can live with.
