DESC: "CompVR series subs uphold the noble Kicker tradition of boneshaking bass, and now they are available at special closeout prices! The awesome C15d-8 15"" woofer delivers premium low-frequency performance, and its 8-ohm impedance makes it the perfect candidate for multi-sub setups.Kicker houses the CompVR's powerful, flex-resistant poly cone with its Inverted Structural Dome in a non-resonant steel basket for great accuracy. The brawny suspension teams up with perimeter venting and a vented pole piece to keep the sub running cool and your music sounding hot. A double-stitched foam surround minimizes cone distortion and resists deterioration from heat and humidity.The C15d-8 is designed for use in a small, sealed enclosure. This rugged sub will handle big-time power and throw it back as consistent, high-impact bass! "
