JL AUDIO M770-TCX-SG-TB # 91760 Tower Coaxial Speaker System, Titanium/Black
The JL AUDIO M770-TCX-SG-TB oversized 7.7-inch design 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 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.
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 JL Audio M770-TCX-SG-TB 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.
TCX (aka Tower Coaxial) models have woofers specifically engineered for enclosed operation. What does this mean? This means that they are designed to operate within an enclosure. More specifically, the woofer design is optimized to operate with a small volume of air behind it (ideally less than 1.5ft³). The bass response of the speaker will suffer significantly if placed in a large enclosure or in an Infinite Baffle (aka “Free Air”), so make sure your system is planned accordingly. This makes them ideal for wakeboard tower systems, custom tower pods or other small enclosure applications . The M-Series is purpose-engineered and built for real marine duty and has been specifically designed to deliver maximum audio performance in any open-air boating environment.
High Performance Highs
A 1-inch pure silk dome tweeter handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics that ultimately result in extremely transparent crisp audio. You will appreciate the clean, articulate high-frequency response of the M-Series dome tweeter, especially at higher volume levels. The tweeter is specially treated to withstand the harsh marine environment, and is optimized to provide sound that will cut through even the most demanding of those marine environments.
True Marine Tested Design
Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer’s motor system to prevent corrosion. The system’s true 2-way passive crossover network is sealed within the protective capsule and mounted to the woofer’s frame so that it does not require additional mounting provisions and is protected from the harmful elements. JL Audio utilizes Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments to ensure that the M-Series not only sound great in your boat, but will also sound great for many, many years.
