Know before you buy
An IPX5 rating means these speakers are protected against low-pressure water jets from any angle. While they are fully marinized and built to withstand salt, spray, and rain, they are not designed to be submerged in water.
These speakers do not have a built-in amplifier, so they require an external marine-grade amplifier or a head unit with sufficient power to reach their full potential. With a 75W RMS power handling, they are designed to pair well with most standard marine audio systems.
The speakers include an RGB lighting pigtail harness that allows you to connect them to a compatible RGB lighting controller. You will need an external controller to change colors, adjust brightness, or set lighting patterns.
Yes, they are engineered with marine-grade materials, including UV-resistant polymer baskets and a sealed motor structure, specifically to resist corrosion from salt and harsh sun exposure.
The bridge-mounted tweeter is integrated directly into the speaker structure to prevent water from entering the internal components. This design ensures the tweeter remains protected while maintaining clear, high-frequency audio reproduction.
