The HMDDSP24 (HMD8DSP24V), powered by Hertz Marine DSP technology, rich new highs of listening pleasure during navigation. DSP user friendly PC-Software interface make the setup process a breeze, exploiting every single pills of performance from the installed speaker system. The amazing power of 8x85W or 4x260W (RMS@ 4Ω) gives the HMD8DSP24V 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 aluminium with an anti-corrosion treated PCB to ensure years of listening pleasure in open water.
