ATC Loudspeaker Technology

SCM300ASL Pro Active Studio Monitor

The SCM300ASL Pro 3-way speaker is the flagship of ATC's speaker range and is used as the main monitor in many of the world's leading recording studios. The 300 liter housing accommodates two 375 mm bass drivers, an ATC 75 mm "Super Dome" midrange driver and a 34 mm tweeter and, with this assembly, ensures outstanding expansion in the lower frequency range and maximum sound pressure levels of up to 121dB. Each loudspeaker is driven by an external P4 4-channel monoblock power amplifier with an active fourth-order crossover with phase correction, thus ensuring an extremely linear frequency response in the main direction of radiation and in the off-axis range.
