Hertz Marine Audio HMS 12 Inch Sports RGB Marine Subwoofer – Black – 500W RMS – 4Ω

The HMS Marine subwoofers are designed to deliver powerful, precise bass without the need for a dedicated enclosure. Available with Sport or Marine grille options, they integrate easily into a wide range of vessels while enhancing both the sound system and onboard aesthetics. Engineered for high-power infinite-baffle installations, HMS subwoofers feature optimised motor and suspension designs that produce deep, controlled low frequencies while reducing distortion and relieving main speakers from reproducing the lowest bass range.
