7.7-inch (196 mm) Tower Coaxial System, Titanium Sport Grilles

JL Audio M770TCXSGTB

Features

  • Tower Coaxial Speaker System: 7.70 in. woofers with separate 1.0 in. dome tweeters
  • Woofers: Injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated for marine duty. Vented motor with marine-grade stainless steel rear diffuser plate. Precisely engineered dust cap profile for smooth upper-end response. Marine-grade, synthetic fiber spider with progressive roll design. DMA-optimized long-excursion design for enhanced output, bass extension and power handling. UV-resistant polymer baskets encapsulate motor structure. Optimized for tower-mount (small enclosure).
  • Tweeters: High-Efficiency design with neodymium motor system 1-inch silk dome diaphragm with specially formulated treatment to withstand UV and salt-spray exposure. Ferrofluid-cooled and damped for improved response and power handling. Permanent grille-mounted design ensures optimal high-frequency performance with no loss of woofer radiating area.
  • Crossover Networks: True two-way crossover with 1st order low-pass filter and 2nd order high-pass filter. Solid-state tweeter protection prevents tweeter failures due to abuse and resets automatically. Crossovers mount directly to woofer baskets, requiring no additional mounting provision.

M-Series 7.7-inch Marine Tower Coaxial System for Enclosed Use (100 W, 4 Ω) - Titanium Sport 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 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 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.

Sold as a pair.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
