FEATURES




Features:

Marine Tested: Rockford Fosgate uses industry standard tests (ASTM B117 salt/fog and ASTM G154 UV) to ensure the M1-8B speakers are durable in the difficult marine environment.
Tweeters: The 1" balanced dome tweeters are made of LCP (liquid crystal polymer), a high strength/light weight material. The tweeters are bridge mounted, useful in a marine speaker because no opening through the middle of the woofer for the mounting post is needed.
LEDs: There are red, green, and blue LEDs in the back of the tweeter casing, to create a glow on the woofer cone. The LEDs can be powered individually, or in any combination you like. Depending on what combination of LED wires is connected, they light red, green, blue, yellow, pink, aqua, or white. A 12 volt power supply is needed to turn the LEDs on and a 1-amp fuse should be added in-line (fuse not included). The LEDs can also be controlled using Rockford Fosgate's LED Controller (item number 575PMXRGB, sold separately). Two LED power wire harnesses are included with 4-pin waterproof Deutsch DT Series connectors that plug into the speaker frames.
Speaker Terminals: In addition to standard male quick slide terminals, each speaker also has 2-pin waterproof Deutsch terminals. Speaker wire harnesses with 2-pin waterproof Deutsch DT Series connectors are not included.
ICC Crossover: The ICC (Integrated Concealed Crossover) simplifies installation and protects the crossover by concealing it inside the basket, creating a cleaner look and easier installation. The crossover has a 6 dB/octave slope.
VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.
Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
Stainless Steel: The mounting hardware is stainless steel to resist corrosion.
