JL Audio M6-650X-L-SbSb M6 Luxe 6.5 Inch Marine Coaxial Speaker, 75W, 4 Ohms, Satin Black - Sold Individually - Used, Open Box

M6 Luxe speakers are purpose-built to deliver top-flight audio performance and durability in luxury marine installations. Each model is outfitted with a low-profile mounting bezel with integrated tweeter bridge and a fine mesh grille for minimal protrusion into cabin space. The result is a discreet visual appearance able to blend in with the finest vessel surroundings.

A DMA-optimized, long excursion woofer design ensures excellent power handling and a 0.8-inch pure silk dome tweeter, specially treated to withstand harsh salt-water environments, produces clean, articulate high-frequency response, especially at higher volume levels.

A multi-order, true 2-way passive crossover is concealed within the woofer chassis, shielded from vibration and corrosion. Also included, is an automatic, solid-state tweeter protection circuit to minimize the possibility of tweeter failure.

Although M6-650X Coaxial Systems can be used with as little as 25 W per channel, for best audio performance we recommend amplifiers capable of between 75-150 W of continuous power per channel.

Production of all M6 loudspeakers takes place in JL Audio’s Miramar, Florida factory, using global components and materials.
