JBL Club 772 Marine 7.7" Two-way Speaker

The JBL Club 772 (part number JBLMARSPKCB772) is a premium 7.7-inch, 2-way marine coaxial speaker pair designed for open-air installations on boats, yachts, and off-road vehicles. Part of the JBL Club Marine Series, these speakers are heavily engineered to deliver powerful, clear sound that can cut through wind, engine roar, and open water ambient noise. They feature built-in RGB LED cone illumination capable of outputting seven colors out of the box to elevate the visual aesthetic of the vessel. To ensure cosmetically clean integration, they ship with interchangeable twist-lock grilles in both Gloss White and Satin Gray, which fully conceal the mounting fasteners. ⚙️ Technical Description The Club 772 utilizes specialized, non-corrosive materials to survive high UV index exposure, salt water spray, and intense physical wash-downs without compromising acoustic response. 1. Transducer & Acoustic Architecture Woofer Cone: UV-resistant polypropylene cone utilizing a high-roll rubber surround. Unlike paper or foam, these materials do not break down when saturated with moisture. Tweeter Configuration: Bridge-mounted balanced silk dome tweeters. The bridge-mount suspended style completely seals the front face of the woofer cone, ensuring sea spray cannot enter the voice coil motor structure. Chassis Design: One-piece cast polymer basket engineered to combat long-term sun and salt degradation. 2. Electrical & Lighting Specifications Illumination Framework: Integrated multi-conductor RGB LED circuit built beneath the translucent cone assembly. Can be hardwired directly into a 12V boat lighting rail for static coloring or piped into an external LED controller for custom patterns. Quality Tuning: Individually voiced and subjected to Harman Standard Reliability Testing (subjecting units to simulated extreme environments). 3.
