BOSS Audio Systems MR52W 5.25 Inch Marine Speakers, 150 Watt 2-Way Coaxial, White, Sold in Pairs

The BOSS Audio Systems MR52W is a pair of 5.25 inch full-range coaxial marine speakers built for open-air use on boats, docks, and other environments exposed to moisture and sun. Each speaker is a 2-way design combining a polypropylene cone woofer with a 1 inch Mylar dome tweeter, driven by a single 1 inch voice coil, delivering a 150 watt maximum output power rating at 4 ohms impedance. The speakers reproduce a frequency response of 80 Hz to 20 kHz with a system sensitivity of 89 dB (1 W/1 m), giving clear, full-range sound for onboard audio systems.

Weatherproofing is built into the construction: the cone is polypropylene, the surround is treated cloth, and the basket is durable plastic, all finished in white to blend with typical marine trim. Each speaker measures 6.25 inches deep by 6.25 inches wide by 3.25 inches high, with a 2.2 inch mounting depth and a 5 inch mounting hole, making it a straightforward flush-mount replacement or upgrade for compatible marine speaker cutouts. The speakers connect via a terminal block and are intended for use with a marine-rated stereo or amplifier as the audio source.

Sold as a pair, the MR52W is designed specifically for boating and marine audio applications where standard home speakers would fail from moisture exposure. Professional installation is recommended to ensure a secure, weatherproof mount and proper electrical connection.
