At ATI we make heavy-duty amplifiers with proven circuitry, meticulous assembly and rigorous testing designed to deliver state-of-the-art audio for years-- all designed by us and built in our own US factory. It's a simple story, "American Muscle built by American muscle."

We design, engineer, and assemble all ATI products in our 50,000 square foot Southern California factory. Everything is built completely to our specifications and we monitor every aspect of the process ourselves. We're convinced, that our efforts pay off in dependability and sound quality. Our customers agree.
