Monster Performance

The L7X uses a massive triple-stacked ferrite magnet surrounding a hyper-extended pole piece. This creates a large, linear magnetic field and improves heat dissipation for ultra-deep bass at high volume.

Stability is Key

The 3-inch voice coil is supported by a dual-spider suspension system. The double-pressed pulp cone attaches to an ultra-long-throw Santoprene surround, with Kicker's square cone technology and ribbed corners for consistent force and air movement.

Keep it Cool

Kicker's Forced-Air Cooling™ system helps the SoloX run significantly cooler for improved reliability and longevity.

Connected

The SoloX spring-loaded terminals each accept up to 8 AWG wire, with a dual 8 AWG terminal block above for straightforward series or parallel wiring.

Field-Replaceable Recone Kit

The L7X uses a surround compression system, bolt-on spider landing and alignment shims so the pre-assembled cone assembly can be replaced without gluing — getting you back up and running quickly.
