In order to be able to offer optimal sound on boats or other demanding locations, ESX has recently expanded its innovative amplifier range to include the MARINE AUDIO range and now also offers two modern VISION Class D amplifiers to provide amateur captains who would like to hear better and more powerful music on the high seas with the performance they need.
The prerequisite for marine suitability is certification in protection classification IP67, i.e. the two robust amplifiers VMA700.4 and VMA700.1 are not only dustproof, but could even be temporarily submerged under water.
The two VMA amplifiers are therefore well protected even against adverse conditions on land, on water and in the air.
If a front and rear system does not provide sufficient power, you will have no choice but to install a subwoofer.
A subwoofer can relieve the smaller speakers of low tones, allowing them to play much more dynamically.
The lowest tones are then taken over by a large subwoofer, which is ideally powered by a separate amplifier.
The ultra-compact ESX Monoblock VMA700.1  is ideal for this. Every boatman will be happy with the Class D amplifier, which delivers up to 700 watts RMS.
In this model, too, all adjustment controls are well protected behind a waterproof screwed cover,  in order to meet the IP67 protection classification.
