ATC, Acoustic Transducer Company, was founded in 1974 by sound engineer Billy Woodman and they have continued to build some of the best studio speakers in the world. Their monitors are designed to meticulous detail, and they are constantly inventing new drivers and other audio technologies. They are also the choice of sound engineers in top recording studios in the industry.

The SCM45A monitors are tailored for being midfield monitors in medium sized control rooms and offer exceptional clarity and detail. They have separate LF, MF, and HF drivers for a wide range of frequencies, with electronic crossovers to eliminate phase incoherence. The MOSFET Class A/B tri-amp pack delivers 150 watts for low frequencies, 60 watts for mids, and 25 watts for highs, while dual 6.5" woofers give you a strong bass presence. You’ll hear every little detail and change in your sound from monitors that are this meticulously crafted.
