JL Audio M3-650X-C-Gw Marine Coaxial Speakers – #93511

These JL Audio M3-650X-C-Gw are Priced and Sold as Pair.

Classic marine sound

Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These M3-650X-C-Gw 6-1/2″ marine speakers make both possible, thanks to excellent design and the most durable materials. You can mount them in your boat’s cockpit or bulkhead walls, either as stand-alones or in conjunction with a subwoofer.

Tough enough

Supplied with plenty of power, these speakers can overcome that wicked combination of wind, water, and engine noise. The weatherproof mica-filled polypropylene cone is suspended in a durable synthetic rubber surround for long excursion and impactful sound. The UV-resistant polymer basket surrounds and protects the entire structure.

The 3/4″ treated silk dome tweeters deliver brilliant highs, and they’re mounted directly to the classic-style grilles for optimal sound radiation. Even in the roughest waters, you’ll be able to enjoy the fine detail of your favorite tunes.

JL Audio M3-650X-C-Gw M3 Standard Flange 6.5-inch Marine Coaxial System (60 W, 4 Ohm) – Gloss White Classic Grille Purpose-engineered and built for real marine duty, M3 coaxial systems deliver excellent performance at a more affordable price than our maximum-performance M6 models.

The M3-650X-C-Gw 6.5-inch coaxial speaker is designed around the standard marine 6.5-inch speaker format and features a wide mounting flange with a four hole mounting pattern.

The long excursion woofer design and excellent power handling make your music come through loud and clear at speed, or at anchor. The woofer design is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 57 l). Operating this coaxial system in less space will compromise its low frequency performance.

A 0.75-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics.

Although M3-650X-C-Gw Coaxial Systems can be used with as little as 20 W per channel, for best audio performance we recommend amplifiers capable of between 75-100 W of continuous power per channel.
