Marine Tested: JL Audio's marine speakers go through
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 Marine Cockpit Coaxial speaker
features an injection-molded, mica-filled polypropylene cone woofer with
UV inhibitors, a rubber surround and a precisely engineered dust cap profile
for smooth upper-end response. The woofer uses a 1" voice coil, a
marine-grade synthetic fiber spider with a progressive roll design and a
vented motor structure with a marine grade stainless steel rear diffuser
DMA (Dynamic Motor Analysis): DMA is JL Audio's proprietary
method of improving dynamic motor behavior. The DMA-optimized long-excursion
design enhances output, bass extension and power handling of the speaker.
Tweeters: The M650s feature a 1" treated silk dome
tweeter with a specially formulated treatment to withstand UV and salt-spray
exposure. The dome tweeter uses an oversized neodymium magnet for higher
efficiency levels and is Ferrofluid-cooled and damped for improved response
and power handling capabilities.
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 mounting
Polymer Basket And Grille: The Centrex, UV-resistant polymer
basket and grille protects the speaker's woofer, tweeter, crossover and motor
structure from the marine environment.
Infinite-Baffle Operation: The JL Audio M650-CCX-CG is
optimized for infinite-baffle operation so that it can be installed in a
variety of locations, without the need for a dedicated enclosure.
Power Handling: JL Audio recommends two RMS power figures
for this model; 75 watts continuous power handling and 25-150 recommended
amplifier power. We've listed the more conservative 75 watts RMS in the specs
