ATC is one of the best-kept secrets in hi-fi. This company has been making drive units and loudspeakers in the Gloucestershire countryside since the ‘70s, yet the brand has a low profile in all but the studio world. In the US, it is only known for producing pro audio speakers, but therein lies its strength. Many years of experience in providing monitors for the most demanding clients in the audio world mean that ATC speakers are phenomenally capable and almost bombproof. You want loud and clean, look no further.
