The Poly-Planar MA-4054 is a 4" two-way coaxial marine speaker built to handle the harsh conditions aboard a boat. Waterproof construction, Teflon-coated wires, polypropylene cones, mylar tweeters, and plastic frames team up to deliver lasting performance without corrosion worries. An ultra-low magnetic field design keeps nearby compasses and autopilots reading true, and the integral grill means one-piece installation with stainless steel hardware already included. Sold as a pair.
