Poly Planar MA4054W 4" 2-Way Coaxial Marine Speakers with Integral Grill

The Poly Planar MA4054W marine speakers are ideal replacement speakers for boaters who want to upgrade to waterproof performance without changing existing cutout sizes. These ultra-low magnetic field speakers feature canceling magnets and shielded enclosures that significantly reduce magnetic flux, allowing installation just 5" from compasses and autopilots without interference.

The MA4054 combines a mid-range polypropylene cone with a 1" diameter mylar tweeter for full-range frequency response from 65Hz to 20kHz. Designed specifically for the harsh marine environment, these speakers deliver reliable performance with 40 watts RMS continuous power (80 watts peak per pair) through 4-ohm impedance.
