KICKER Solo-Baric L7 Subwoofer remains the most capable subwoofer on Earth. Without question, it's the best-looking, best-sounding square subwoofer available. And it's the only patented one that provides more cone, more air, and more decibels.KICKER engineers left it all on the table for this redesigned Solo-Baric L7, taking cues from the award-winning original that debuted as groundbreaking at the turn of the millennium, and then improving on them. Let there be no doubt, it's the most complete KICKER subwoofer ever developed.The Solo-Baric L7 still revolves around the breakthrough SoloKon, the one-piece, injection-molded cone with full-coverage back bracing that pushes more air and creates louder bass than any like-size round subwoofer. It's good enough that KICKER uses SoloKon across the board as the cornerstone for each subwoofer in the KICKER bass-making family.SoloKon may be a rock star, but it's the unshakeable motor structure behind the scenes that propels it to the forefront. Minor tweaks have given the motor an outstanding rep - dual high-temp voice coils, poly-cotton semi-progressive spider, Spiralead tinsel-lead technology, highly-efficient UniPlate pole-piece/back plate, and a heat-reducing T-cut top plate for enormous power handling. And it's never been cooler with a new solid pole piece that disperses more heat than ever before, and more venting near the SoloKon back brace and spider landing.The distinctive cast-aluminum basket with spring-loaded terminals wraps around and protects these specialized inner workings, with the Solo-Baric crest branded into the back plate.The Solo-Baric L7 remains available in 2-Ohm DVC and conducts business from a sealed or vented box application.
