Description

JL Audio M3-650X-C-Gw

Purpose-engineered and built for real marine duty, M3 coaxial systems deliver excellent performance at a more affordable price than maximum-performance M6 models. The M3-650X 6.5-inch coaxial speaker is designed around the standard marine 6.5-inch speaker format and features a wide mounting flange with a six 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.

JL Marine 6.5

Somewhat basic speakers but they match what I currently had in the boat. Wish they could be a little louder and the RGB color changing be built in for the price of these.
