ultraviolet testing chambers (to simulate years of sun exposure) and salt fog
chambers (to simulate years of exposure to salt-water environments.
Woofers: The JL Audio M770-CCX-CG-WH features 7.7-inch
diameter woofers that provides 20% more sound radiating area than typical
6.5-inch designs. The JL Audio Marine Cockpit woofers features an

Crossover: The JL audio marine speakers utilize a true 2-way
crossover network with 1st order low-pass and 2nd order high-pass circuits. The
crossover network also features a polyswitch solid-state tweeter protection
which prevents tweeter failures due to abuse and resets automatically. The
crossover mounts directly to the polymer woofer basket, requiring no additional
