Free-Air 12" Subwoofer for High-Performance Bass

The Kicker 45KMF124 is a 12" marine transducer engineered specifically for free-air (infinite baffle) applications, designed to provide a massive low-frequency foundation without the need for a dedicated enclosure. By utilizing the open air-space of a boat’s hull or storage locker, this driver creates a high-output bass experience that is both space-efficient and physically commanding. This model features a single 4-Ohm voice coil, allowing it to draw maximum current from marine amplifiers for increased efficiency and impact.

Built to Kicker’s "Real Marine" specifications, the 45KMF124 is designed to thrive in the world’s most punishing environments. It features a injection-molded polypropylene cone and a co-molded Santoprene surround for consistent, high-excursion performance. The system is anchored by the UniPlate back plate and pole piece, which acts as a thermal heat sink to keep the voice coils cool during extended high-volume sessions. With a rustproof polymer basket and stainless-steel hardware, this 12" driver is the ultimate solution for enthusiasts who want flagship-level bass on the open water.
