Hertz HMS 12 B4-LD-C

The new HMS 12 marine classic charcoal grille subwoofer is optimized to perform in open baffle applications for deep and punchy bass without the need to build a dedicated enclosure. HMS 12 is available at 2 or 4-ohm single voice coil versions, featuring a stunning 500 W continuous power handling. The classic grille features built-in LEDs. The motor and suspension design is optimized for high-power, infinite-baffle operation featuring long linear excursion capability for tremendous output with low distortion.

Hertz Marine subwoofers not only add tons of bass output to your system but also relieve the main speakers from the hard work of reproducing the lowest frequency range, thus maximizing overall system performance for unlimited sound pressure and emotion!
