Product Details

JL Audio M-Series Black 7.7" Marine Tower Component System, Model M770TCSSGTB

For Enclosed Use (100 W, 4 Ù) - Titanium Sport Grille. Purpose-engineered and built for real marine duty, the M-Series component systems deliver maximum audio performance in any open-air boating environment. The oversized 7.7-inch design of the M770-TCS component woofer results in increased efficiency (more output for a given amount of power). Combine that advantage with long excursion and excellent power handling and you have a speaker system truly capable of playing loud and clear in a powerboat at speed. The M770-TCS component woofer is optimized to operate in a small sealed enclosure, such as a tower speaker system.

To keep up with the capabilities of the component woofer, we employ a 1-inch pure silk dome tweeter that is specially treated to withstand the marine environment. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics. You will appreciate the clean, articulate high-frequency response of the M-Series dome tweeter, especially at higher volume levels. A true 2-way passive crossover network is sealed in a protective capsule and mounted to the woofer's frame so that it does not require additional mounting provisions. Although M770-TCS Component Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 75-150W of continuous power per channel. Sold as a pair.
