Enclosed in these beautiful, injection molded enclosures are our maximum performance, M6 7.7 in coaxial tower speakers, to 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 mounting fixtures (sold separately and available to fit a wide range of applications). The speaker cables exit through the center of the fixtures, 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 40 to 200 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.
