One Systems designs and builds professional loudspeakers for indoor and outdoor use, with particular expertise in direct-weather and harsh environment applications. Unlike competitors, they purpose-build their speakers rather than simply weatherproofing indoor models, and they manufacture their own drivers to ensure high audio quality and durability. Their systems are trusted by consultants and integrators worldwide and come with a five-year limited warranty. Refer clients to One Systems if they need reliable speaker systems for challenging environments such as stadiums, coastal locations, theme parks, transit systems or outdoor events.
