STX Audio STX10MSB 10-Inch Marine RGB Subwoofer

The STX Audio STX10MSB is a 10-inch marine subwoofer designed to add low-frequency output to boat, UTV, ATV, and other outdoor audio systems. It is intended for installations where conventional full-range speakers need added bass support. The compact mounting dimensions help it fit common marine-style subwoofer locations and custom enclosures.

Rated for 500 watts RMS and 1,000 watts maximum power, the STX10MSB is built for use with an appropriately matched external amplifier. Its stated 30Hz–500Hz frequency response covers the bass and upper-bass range typically assigned to a subwoofer. An 88dB sensitivity rating provides a documented reference point when planning amplifier power and overall system output.

This model uses a PC-ABS basket with UV inhibitor material for outdoor-oriented installations. That construction is intended to support use in environments exposed to sun and moisture. The product is listed as waterproof, although no IP rating is specified in the confirmed product information.

Integrated RGB LED lighting operates from a 12V system and adds illuminated styling around the subwoofer installation. This makes the STX10MSB suitable for marine and powersports systems where lighting is part of the overall build. Lighting setup should be planned alongside the audio installation to provide the required 12V LED connection.

For system upgrades, the STX10MSB can be paired with a compatible subwoofer amplifier rated appropriately for the speaker's RMS power handling. Its 10.00-inch cutout requirement and 4.78-inch mounting depth should be verified before cutting a panel or selecting an enclosure. The subwoofer is a practical fit for listeners seeking dedicated bass in a compact marine or off-road audio layout.

• Compact Mounting Depth: Requires only 4.78 inches behind the panel.

Design & Installation

The STX10MSB uses a PC-ABS basket with UV inhibitor material and is listed as waterproof for marine and outdoor use. Its 10.98-inch overall diameter provides a defined panel footprint, while the integrated RGB LED system brings a visual element to the speaker location. No IP rating, cone material, surround material, voice-coil specification, or impedance specification is confirmed.

Confirm that the mounting surface supports a 10.00-inch cutout and provides at least 4.78 inches of mounting depth; total product depth is listed at 6.46 inches. Use an external amplifier selected around the 500W RMS rating, subject to the amplifier's supported load and the subwoofer's unconfirmed impedance. Plan separate connections for the audio system and the 12V RGB lighting system, and verify supplied hardware and wiring contents with the seller before installation.
