Boss Audio 4" MRWT40 Waketower Speakers - Black - 400W

The Boss Audio 4" MRWT40 Waketower Speakers deliver 400 watts of total output power across a pair of marinized enclosures designed specifically for mounting on wake tower pipes. These 4-inch speakers are engineered to handle the saltwater environment and constant vibration exposure that comes with serious boating, making them a practical upgrade for anyone running a boat audio system that demands both durability and performance.

Each speaker handles up to 100 watts RMS, allowing the pair to produce clean, high-volume output without distortion under normal operating conditions. The 4-inch polypropylene woofer cone is matched with a rubber surround—materials selected for their resistance to UV exposure, salt spray, and temperature fluctuation. The marinized enclosure construction protects internal components from moisture and corrosion, critical factors in offshore and coastal boating where salt air accelerates component failure. The mounting system accommodates standard 1.5" to 2" wake tower pipes, the industry-standard diameter on most boat towers, making installation straightforward without custom fabrication or adapters.

These speakers suit weekend fishermen, water sports enthusiasts, and serious offshore anglers who want reliable audio without frequent replacement or maintenance. The height of 14 inches and compact footprint (9 x 7 inches) position the speakers effectively for deck-level sound coverage without excessive profile or wind load. Weighing 6.2 pounds per unit, they mount securely without imposing structural stress on lighter tower frames common on center consoles and bass boats.

Marine-grade speakers must balance sound quality with environmental durability—a challenge that separates purpose-built marine speakers from general-purpose aftermarket options. The MRWT40's engineering prioritizes survival in saltwater conditions while maintaining rated output, making it a logical choice for permanent boat installation where replacement is costly and inconvenient.
