Product Description

JL Audio MX770-ETXv3-SG-TKLD-B 7.7″ Enclosed Tower Coaxial System- Satin Black – #91199


JL Audio MX770-ETXv3-SG-TKLD-B 7.7″ Enclosed Tower Coaxial System. Enclosed in these beautiful, injection-molded enclosures are our high-performance, MX-Series 7.7-inch coaxial tower speakers. Specifically tuned for tower enclosure applications, these coaxial drivers deliver clean, loud audio that can be heard well beyond the boat when mounted up high.

The enclosures feature a decorative, aluminum logo cap on the end opposite the speaker, which can be oriented to match any custom mounting application. Each is designed to mate with one of our clamp systems (sold separately, and available to fit a wide range of pipe diameters). The wire exits through the center of the mount, staying high and dry, and out of sight. Professional installation is strongly recommended.

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 blue glow, adding a dramatic visual experience to your high seas journey.

For best results, we recommend powering these systems with an amplifier in the 25-150 W per channel range.

Like all JL Audio marine speakers, this system is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
