The JL Audio M6-880X-L-GwGw 8.8-inch marine coaxial speakers represent one of the most powerful and best-sounding marine speaker designs available today. Built in the USA and engineered specifically for open-air marine listening, they deliver huge output, deep mid bass and studio-grade clarity—making them the benchmark upgrade for premium boat audio systems.
Each speaker features JL’s oversized long-excursion 8.8" woofer, using a mineral-filled polypropylene cone, marine-treated suspension and durable synthetic rubber surround. This larger cone area provides significantly more midbass and fuller sound compared to typical 6.5" or 7.7" speakers. A 1.25-inch silk dome tweeter is integrated into JL’s bridge-mounted assembly, projecting smooth, refined high frequencies across wide deck and cockpit areas without harshness or distortion.
With 125 W RMS and 250 W peak power handling at 4 ohms, these speakers are designed to shine with JL Audio’s M-Series and MVi marine amplifiers, delivering high output with exceptional fidelity.
The M6 series is engineered to survive real saltwater use. Corrosion-resistant Centrex® baskets, sealed crossover components, UV-stable materials and stainless hardware ensure long-term reliability. Every pair is tested extensively for salt-fog, UV exposure, vibration and moisture to exceed marine industry standards.
Integrated RGB LED lighting (JL’s “L” series) sits behind the grille to deliver smooth, premium lighting effects throughout your cockpit or deck area. The GwGw finish (Gloss White Trim with Gloss White Grille) provides a clean, modern aesthetic ideal for luxury vessels, sportsboats, RIBs and cruisers.
