JL Audio M770-TCX-CG-TB
M-Series 7.7-inch Marine Tower Coaxial System for Enclosed Use (100 W, 4 Ω) - Titanium Classic Grille
Purpose-engineered and built for real marine duty, M-Series coaxial systems deliver maximum audio performance in any open-air boating environment.
The oversized 7.7-inch design of the M770-TCX coaxial 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-TCX coaxial is optimized to operate in a small sealed enclosure, such as a tower speaker system. If you need a system with a 7.7-inch component woofer that operates without a dedicated enclosure, select our M770-CCX, instead.
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.
A 1-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. You will appreciate the clean, articulate high-frequency response of the M-Series dome tweeter, especially at higher volume levels.
Although M770-TCX Coaxial Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 75-150 W of continuous power per channel.
