ATC SCM 11 (2006) - "The type of speaker that could play any type of music with ease. The Gloucestershire-based company opted for a sealed cabinet for agile bass performance. The speaker's two-way design had a mid/bass driver that was developed in-house and featured a hefty motor system."

ATC SCM 100A (2011) - "Imposing and functional lookers, but capable of great sound. Rarely had we heard bass sound as good, as loud or as nuanced. Tonally they were spot-on, and capable of being immensely muscular as well as delivering a dose of subtlety too."
