Description
The Kicker SoloX L7X 18-inch is a competition-oriented square subwoofer designed for very large, high-output vented enclosures. It is available in 1-ohm and 2-ohm versions and carries a recommended amplifier-power range of 1,000–2,000 watts RMS.
A three-inch aluminum voice-coil former, triple-stacked ferrite motor, dual-spider suspension and Forced-Air Cooling support high excursion and sustained output. The bolt-in field-replaceable cone, voice-coil and spider assembly can be serviced without glue when the matching-impedance recone kit is used.
