Kicker 49L7X151 - SoloX L7X 15-Inch (38cm), 3" Coil, Ferrite Competition Subwoofer, 1-Ohm

The KICKER SoloX L7X Ferrite Competition Subwoofer brings the most advanced bass technology and unprecedented performance, from the guys who invented it for a vehicle. A motor like no other – it includes a massive, triple-stacked ferrite magnet surrounding a hyper-extended pole piece, engineered for an enormous, more linear magnetic field and amazing heat dissipation. It's ultra-deep bass at very high volume. L7X's three-inch voice coil is supported by a dual-spider suspension system, and the double-pressed pulp cone is attached to an ultra-long-throw Santoprene surround - equipped with KICKER's square cone tech and ribbed corners for continuous force and air movement. Field-Replaceable Recone Kit - Using an exclusive, surround compression system, bolt-on spider landing, and helpful alignment shims, repairing an L7X is no sweat!
