The STX Audio STX65MXW is a 6.5-inch marine coaxial speaker designed for audio systems exposed to water, sunlight, and outdoor use. It is suited to boats, UTVs, ATVs, and similar applications where conventional interior speakers may not be appropriate. Its white finish and integrated RGB illumination help it coordinate with marine and powersports installations.
This 2-way coaxial design places the high-frequency driver within the main speaker assembly, providing a compact full-range speaker solution. It is intended to reproduce midrange and high-frequency content from a compatible marine, powersports, or vehicle audio system. The design can simplify an upgrade where space for separate tweeters and crossovers is limited.
The STX65MXW is rated at 300 watts RMS and 600 watts maximum power. Power handling should be matched carefully with the output rating and gain settings of the connected amplifier or head unit. Proper system setup helps support clean playback and protects the speakers from overload.
For outdoor durability, the speaker uses a PC-ABS basket and an ASA grille. These materials are specified for resistance to water, UV exposure, and demanding environmental conditions. This construction makes the STX65MXW a practical option for open-air installations where weather resistance is a key consideration.
Its 6.8-inch overall diameter, 4.84-inch mounting width, and 2.41-inch mounting depth are designed for many 6.5-inch factory and aftermarket speaker locations. The relatively shallow mounting depth can be useful in panels with limited rear clearance. Always measure the available opening, mounting surface, and depth behind the panel before installation.
Key Features
- 6.5-Inch Marine Speaker: Compact coaxial format for marine and powersports audio locations.
- 2-Way Coaxial Design: Combines high- and mid-frequency reproduction in one assembly.
- 300W RMS Rating: Supports amplifier matching based on continuous power handling.
- 600W Maximum Power: Provides a stated peak-power handling reference.
- Integrated RGB LEDs: Adds 12V accent lighting to compatible installations.
- Marine-Grade Materials: PC-ABS basket and ASA grille support outdoor use.
Design & Installation
The STX65MXW uses a white PC-ABS basket with an ASA grille for a marine-oriented exterior. The materials are specified to resist water, UV rays, and harsh outdoor conditions. Its integrated RGB LED lighting adds a visual element without changing the speaker's coaxial mounting format.
Confirm that the installation location supports the 6.8-inch overall diameter, 4.84-inch mounting width, and 2.41-inch mounting depth before cutting or drilling. Connect the speaker to an appropriately matched audio source or amplifier, and wire the RGB lighting to a suitable 12V lighting circuit according to the installation instructions. These speakers are intended for boats, UTVs, ATVs, and other outdoor-capable audio systems.
