STX Audio STX65MTB 6.5" Marine Tower Speaker

The STX Audio STX65MTB is a 6.5-inch marine wakeboard tower speaker designed for boats and off-road recreational vehicles. Its enclosed pod design provides an externally mounted audio solution for wakeboard towers, roll bars, and similar tubular mounting locations. It is intended for systems where conventional in-panel marine speakers are not the preferred fit.

This speaker is suited to boat, UTV, ATV, and off-road audio upgrades that need sound aimed toward passengers or an open riding area. The multi-angle rotating aluminum clamp allows the pod to be directed after installation. That adjustability can help tailor coverage to the seating area or riding space.

The STX65MTB uses a 2-way speaker design with a 6.5-inch injection-molded polypropylene woofer and a 0.8-inch neodymium tweeter. This configuration is designed to reproduce midrange and high-frequency detail from a compact tower-mounted enclosure. Listed power handling is 300 watts RMS and 600 watts peak.

For outdoor use, the speaker is housed in a sealed ASA enclosure and uses a Santoprene surround. The product is described as water-resistant, UV-resistant, and corrosion-resistant for marine and off-road environments. Its materials focus on supporting installation where sun, moisture, and changing weather are regular considerations.

Integrated 12V RGB LED lighting adds illumination around the speaker for nighttime use. The speaker can be incorporated into a compatible amplified marine or powersports audio system, while its RGB wiring is connected separately from the audio wiring. It is a practical option for adding a directional tower speaker without changing the vehicle's main source unit.

Design & Installation

The STX65MTB combines a sealed ASA speaker pod with an injection-molded polypropylene woofer and Santoprene surround. Its aluminum mounting clamp is designed for tower, roll-bar, and similar tubular applications. The black enclosed form keeps the speaker assembly externally mounted rather than requiring a conventional speaker cutout.

Confirm the mounting-bar diameter, clearance, clamp fit, and wiring route before installation. Connect the speaker to an amplifier matched appropriately to its listed 300-watt RMS rating, and run the RGB lighting connection to a suitable 12V RGB lighting setup. The package is listed with an adjustable aluminum mounting bracket, mounting hardware, and an RGB LED wiring connection kit.
