JL Audio M6-8IB-S-GwGw-4 8" Marine Infinite-Baffle Subwoofer is an 8-inch marine subwoofer engineered for infinite-baffle (free-air) installations where dedicated enclosures aren’t practical. Built on JL Audio’s high-performance M6 platform with a Gloss White Sport grille, it delivers deep, controlled bass and stands up to real marine environments.
Rated for 200 W RMS at a nominal 4 Ω, this driver is optimized for free-air subwoofer use and pairs well with 50–200 W of clean amplifier power. The injection-molded mica-filled polypropylene cone, synthetic rubber surround, and marine-grade construction provide excellent performance in saltwater, humidity, and UV exposure. This sub takes the deep-bass workload off your main speakers so your entire system can play louder and cleaner.
