Enclosed in these beautiful, injection molded enclosures are our high performance, M3 7.7 in 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. For best results, we recommend powering these systems with an amplifier in the 25 to 150 W per channel range. Like all JL Audio marine speakers, this system is built to withstand a real salt water marine environment and deliver years of listening enjoyment.
