NAUTIC - Rock the Boat!

MB Quart’s compliance to the American Society for Testing of Materials ASTM D4329-05 ensures the Nautic’s polymer speaker assembly is resistance to deterioration, physically, electrically, and mechanically when exposed to all combinations of ultra-violet light, natural sunlight, extreme heat, extreme cold and saltwater in marine applications. Non-compliant speakers will deteriorate in the salt-laden marine environment.
