3x MTX MA8H-B - Marine 8” 150-Watt RMS 4Ω Compression Horn Speaker Pair Black IP-67 Rated with RGB Lighting and Customizable Grille (MA8H-B)
MA8H-B Marine 8" 150-Watt RMS 4Ω Compression Horn Speaker Pair with RGB Lighting
The MTX MA8H-B is an 8-inch marine compression horn speaker pair designed for focused, high-efficiency sound in open-water and open-air environments. Using a coaxial 8-inch compression horn speaker design with a dedicated high-frequency compression driver, it is built to project clear audio over distance while maintaining marine-grade durability and integrated RGB lighting for a customizable appearance.
Overview
Focused Marine Output with Compression Horn Design
The MA8H-B is built for marine and open-air systems that need sound to carry with more focus and clarity. Its coaxial 8-inch compression horn speaker format is designed to provide efficient projection in environments where traditional speaker dispersion may not be as effective over distance.
Finished in black and built with marine-ready construction, the MA8H-B combines directional output, weather-tested durability, integrated RGB lighting, and installation-friendly dimensions in a format suited for exposed environments.
- 8" coaxial compression horn speaker pair.
- Built for open-water and open-air applications.
- Designed for focused, efficient sound projection.
Marine Construction
Weather-Tested for Harsh Conditions
The MA8H-B is engineered for prolonged exposure to sun, water, and salt. The front side is IP67 rated and the speaker has passed 500 hours of ASTM G154 UV testing and 500 hours of ISO 16750-4 salt spray testing. An ASA impact-resistant grille adds protection against physical wear in marine environments.
- Front-side IP67 rated.
- 500-hour UV testing and 500-hour salt spray testing.
- ASA impact-resistant grille for added durability.
Feature Highlights
What the MA8H-B Adds to a Build
Horn Design
Dedicated Compression Driver for Forward Projection
Unlike a traditional coaxial speaker layout, the MA8H-B uses a dedicated high-frequency compression driver and horn to project sound more efficiently. This design is intended to improve clarity and intelligibility over distance in open-water and open-air environments where sound needs to carry.
- Dedicated high-frequency compression driver.
- Horn-loaded design for focused sound projection.
- Built for improved distance performance in open-air use.
Styling & Installation
RGB Lighting with Marine-Focused Fitment
Integrated RGB LED lighting gives the MA8H-B added visual impact, while the paintable grille overlay helps create a more coordinated installation. Quick-disconnect speaker and RGB terminals add practical setup benefits for marine installs.
- Integrated RGB LED lighting.
- Paintable grille overlay.
- Quick-disconnect speaker and RGB terminals.
- Black finish for marine and custom installs.
