Design
At Anthem, we have one simple goal – to design, engineer and manufacture audio/video products that deliver premium performance and convenience at a reasonable price. We do this by spending thousands of hours selecting and testing components, carefully designing our own circuit topologies, and backing them with robust power supplies that ensure maximum long-term quality and reliability. We achieve this with our team at the Paradigm/Anthem Research Center and their decades of combined experience.
