POLY-PLANAR Marine Speakers MA4055 Two-Way Coax Integral Grill Performance Speakers

Ideal replacement speakers for boaters who want to upgrade to waterproof speakers without changing the cutout size.

Powerful speaker magnets really play havoc with compasses—unless they’re Ultra-Low Magnetic Field speakers. Because their canceling magnets and shielded enclosures significantly reduce magnetic flux, you don’t have to mount them 5″ from compasses and autopilots like other systems.

The MA4055 speakers combine a mid-range polypropylene cone with a 1″dia. mylar tweeter for full-range frequency response. 80 watts peak power per pair. 4-ohm impedance. Stainless steel mounting hardware included.
