The JL Audio M6-10IB-L-GwGw-4 10-inch marine subwoofer delivers deep, authoritative bass engineered specifically for open-air boat listening. Built in the USA and designed for true free-air (infinite baffle) installation, this premium M6-series subwoofer produces rich, accurate low-frequency performance without requiring an enclosure—perfect for bulkheads, consoles, helm stations and under-seat mounting.
This model features JL Audio’s long-excursion 10-inch marine woofer, using a mineral-filled polypropylene cone, synthetic rubber surround, and a precision-engineered marine motor system. The result is clean, powerful bass output that stays tight at high volume and cuts through engine noise, wind and open-water acoustics.
A 0.8" marine-grade LED lighting assembly sits behind the grille, illuminating the woofer with a smooth, premium white glow. The Gloss White Trim + Gloss White Grille (GwGw) finish blends seamlessly with modern boat interiors and OEM marine styling.
Built to handle 250 W RMS / 4-ohm impedance, the M6-10IB-L pairs perfectly with JL Audio’s M-Series or MVi DSP marine amplifiers. This free-air version is engineered for open-baffle mounting where no sealed enclosure is used.
As part of JL’s flagship M6 Real Marine lineup, the M6-10IB-L is tested for extreme UV, salt fog, thermal cycling, and vibration—ensuring reliable long-term performance in harsh, saltwater environments.
