• 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 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.
• Integrated into the Sport Grille’s frame, the internal LED lighting assembly was meticulously designed to uniformly illuminate the woofer’s cone area with a lively glow, adding a dramatic visual experience to your high seas journey. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.
• Although M3-650X 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.
• Sold as a pair.
