Hertz HEX4CC 4" Marine Coaxial 30W RMS IP65 Black Grille Certified Compact

Hertz 4" Marine Coaxial Speaker 30W RMS / 60W Peak, IP65, ASTM UV & Salt Fog Certified, Black Classic Grille, Twist-Lock, 52mm Mounting Depth.

Product Overview

The Hertz HEX 4 C-C extends the Pure Marine HEX range into the compact 4-inch format engineered for consoles, cabins, T-tops, and secondary listening areas where installation space is limited and depth is at a premium. At just 52.3mm mounting depth and a 95mm cutout diameter, the HEX 4 C-C fits where larger speakers cannot while delivering the same Pure Marine certified acoustic performance and build quality as the rest of the HEX range.

Hertz Pure Marine Certified IP65 water jet, ASTM-D4329 UV, and ASTM-B117 salt fog tested. The FEM-optimised neodymium tweeter delivers wide off-axis dispersion for in-boat listening, and the 25mm woofer voice coil is tuned specifically for infinite baffle applications. Sealed integrated crossover with resettable solid-state tweeter protection, nickel-plated corrosion-resistant terminals, and the Black Classic sound-transparent mesh grille with twist-and-lock mounting complete the package.
