Description

The Rockville MS525B 5.25″ 400W Marine Boat Speakers are engineered for clear, powerful sound in marine and outdoor environments. With 400W peak and 200W RMS per pair (100W each), these 2-way speakers use an injection-molded polypropylene cone and 1″ ASV voice coil to deliver rich audio across a 110Hz-20kHz range. Their 87dB +/-2dB sensitivity and 1″ PEI diaphragm tweeter with NdFeB magnet ensure crisp, detailed highs.

Built to handle the elements, these IP56-rated speakers are fully marinized against salt and freshwater, with a rustproof and anti-UV ABS basket and grill for long-lasting durability. Installation is simple with the included stainless steel screws, speed clips, and template. Compact dimensions-5.79″ total diameter, 5.31″ cutout diameter, 2.56″ total height, and 1.85″ mounting depth-allow for versatile placement in boats, RVs, ATVs, and other vehicles.

Key technical details include a 6 oz Y30 ferrite magnet, resonant frequency (F0) of 120Hz +/-20%, Fs of 142Hz, and 4-ohm impedance for compatibility with most marine audio systems. Whether on the water or off-road, the MS525B delivers reliable, high-quality sound built to last.
