Subwoofer

The 200-watt sub has a front port along with a blue LED light that indicates that the unit is powered up. The sub features a down-firing 8-inch injection-molded woofer. The driver has Energy's Ribbed Elliptical Surround--the rubber "rim" that surrounds the woofer cone has molded-in ribs--which Energy claims lowers distortion and allows the subwoofer to play louder than more-conventional designs.
