HMD8 DSP
The amazing power of 8 * 85 W or 4 * 260 W (RMS@ 4Ω) gives the HMD 8DSP the capability to drive with authority the complete speaker system generating tons of crystal clear SPL up to 3 different zone of the vessel. “Power for the Waves” design philosophy features a sturdy enclosure made of extruded aluminum with an anti-corrosion treated PCB to ensure years of listening pleasure in open water.
