The JL Audio M6-650X-L-GwGw 6.5 inch premium marine coaxial speakers are designed for boat owners who want true hi-fi sound and modern styling with integrated lighting. Tuned specifically for open-air listening, they deliver clean, powerful audio that cuts through wind, engine noise and wave action, while the built-in white LED lighting adds a refined visual touch to your cockpit or deck areas.
Each speaker uses JL Audio’s long-excursion 6.5 inch woofer with a mineral-filled polypropylene cone and durable synthetic rubber surround to provide tight, controlled midbass and midrange, even at higher volume levels. A 0.75 inch silk dome tweeter is mounted coaxially on the grille to project smooth, detailed high frequencies across a wide listening area, so vocals and instruments remain clear wherever you sit on board.
Engineered from the ground up for real-world marine use, the M6 range is built to withstand harsh UV exposure, salt fog, humidity and regular washdowns. The speakers use JL’s Centrex® polymer baskets and grilles, corrosion-resistant hardware and marine-grade terminals, all tested to rigorous environmental standards for long-term reliability afloat.
The “GwGw” finish combines a classic gloss white grille and gloss white frame to blend cleanly with most modern boat interiors. Integrated cool white LEDs behind the grille provide an even, elegant glow (not RGB), ideal for premium sportboats, cruisers and tenders where you want subtle lighting rather than multi-colour effects.
With 75 watts RMS and up to 200 watts peak power handling at 4 ohms, these speakers are an ideal match for JL Audio marine amplifiers or other quality marine amps and head units. They drop into most standard 6.5 inch cut-outs, making them a strong upgrade over factory-fitted speakers.
