STX Audio STX10MSW 10" Marine Subwoofer

The STX Audio STX10MSW is a 10-inch marine subwoofer designed to add low-frequency output to boat, powersports, and outdoor audio systems. It is intended for installations where standard full-range speakers need added bass support. Its marine-compatible construction and integrated RGB lighting make it suited to exposed recreational environments.

With a stated 500-watt RMS power rating and 1000-watt maximum power rating, the STX10MSW is built for amplified subwoofer applications. Its 30Hz-500Hz frequency response is specified to cover deep bass through upper-bass output. An 88dB sensitivity rating is provided for system-planning purposes.

The subwoofer uses a true 10-inch fitment with a 10.00-inch cutout diameter and 10.98-inch overall diameter. This helps it fit installations designed around a 10-inch marine subwoofer opening. Its 4.78-inch mounting depth supports placement where rear clearance is limited.

For outdoor durability, the STX10MSW uses a PC-ABS basket with UV inhibitor and an ASA grille. These materials are specified for resistance to water exposure and sunlight in marine and powersports use. The product is listed as waterproof for its intended application.

Integrated 12V RGB LED lighting adds selectable visual accent lighting to a compatible installation. The STX10MSW can be used as the bass section of a marine audio upgrade alongside an appropriately matched amplifier and existing full-range speakers. It is a practical option for boats, UTVs, ATVs, and similar systems needing a dedicated 10-inch subwoofer.

Design & Installation

The STX10MSW combines a PC-ABS basket with UV inhibitor and an ASA grille for a marine-oriented design. Its waterproof listing and outdoor-focused materials make it appropriate for installations exposed to sun and moisture. The 10.98-inch overall diameter and 6.46-inch total depth should be considered when checking panel and enclosure clearance.

Plan for a 10.00-inch cutout and at least 4.78 inches of mounting clearance behind the mounting surface. Use an amplifier selected to suit the subwoofer's stated power handling, and plan separate 12V wiring and control as needed for the RGB lighting. Confirm available mounting space, amplifier compatibility, and lighting connections before installation.
