STX Audio STX80MTW 8-Inch Marine Tower Speaker

The STX Audio STX80MTW is an 8-inch marine wakeboard tower speaker built for boats, UTVs, ATVs, and other exposed outdoor audio installations. Its enclosed tower-mounted format places sound above the deck or cabin area, helping direct music toward riders and passengers. The integrated RGB lighting also adds visible accent illumination for nighttime use.

This is a 2-way speaker design with an 8-inch injection polypropylene woofer and a 0.8-inch NdFeB tweeter. The woofer is intended to provide midbass presence, while the separate tweeter handles higher-frequency detail. STX rates the speaker at 400 watts RMS and 800 watts maximum power.

For outdoor use, the STX80MTW uses a sealed ASA enclosure and a Santoprene surround. These materials are specified for water resistance, UV resistance, and exposure to marine or off-road conditions. The enclosed construction also keeps the speaker assembly suited to tower and roll-bar placement.

A rotating, multi-angle aluminum clamp lets the enclosure be aimed after mounting. This is useful when positioning the speaker on a wakeboard tower, roll bar, or similar tubular structure where listening areas vary. Adjusting the aim can help focus sound toward the intended seating or riding area.

The STX80MTW can serve as a single tower-speaker addition or as part of a larger marine or powersports audio system. Its 12V RGB LED lighting connection is separate from the audio function and should be planned with the vehicle or boat's lighting setup. Match the speaker to an amplifier only after confirming the amplifier's supported load and output specifications.

Key Features

• 8-Inch 2-Way Design: Combines a dedicated woofer and tweeter in one tower enclosure.
• 400W RMS Rating: Provides a published continuous power-handling reference for system planning.
• Injection Polypropylene Woofer: Supports midbass reproduction in an outdoor-ready speaker design.
• NdFeB Tweeter: Handles high-frequency detail through a compact 0.8-inch driver.
• Marine-Grade Enclosure: Sealed ASA construction is specified as water- and UV-resistant.
• Adjustable RGB Mounting System: Aluminum clamp allows directional aiming and integrated 12V RGB illumination.

Design & Installation

The STX80MTW uses a sealed ASA enclosure with a Santoprene surround, materials selected for marine and off-road exposure. Its 8-inch woofer, 0.8-inch tweeter, and integrated RGB LED system are housed in a single tower-style enclosure. The aluminum clamp is designed to rotate for adjustable aiming.

Mount the speaker on a suitable wakeboard tower, roll bar, or comparable structure using the supplied clamp and mounting hardware. Connect the speaker to a compatible external audio amplifier, with amplifier matching finalized after verifying the system impedance and wiring requirements. The RGB lighting uses a 12V connection; the package listing identifies an RGB LED wiring connection kit, but does not identify an RGB controller.
