Technologies
HMD1
ADVANCE D-CLASS

Thanks to the Hertz advanced D-CLASS output stage, HMD1 joins maximum sound quality with unmatched efficiency to be very compact and easily installed in any position of the boat.

HMD1
CORROSION RESISTANT

Electronics components corrosion caused by exposure in wet environments is totally neutralized by the use of dedicated Marine-grade (epoxy coated) PCB boards.

HMD1
SALT FOG PROOF

To satisfy the standards required by ASTM-B117, Hertz Marine products are tested with massive salt fog spray to ensure a complete resistance to corrosion, typical of this atmospheric agent.

HMD1
WATER JET TESTED

The protection grade IP64 defines all the Hertz Marine products as totally protected against water jets of different entities, making them highly performant in the marine environment.
