ATC Loudspeakers SCM45A Pro (single)

The SMC45A Pro, ATC's mid-sized three-way active loudspeaker in the SCM range, can be placed in both near- or mid-field positions. It shares many features with the SMC25A Pro, and completes ATC's professional active monitoring loudspeaker range. Producing an excelent linear response across the midrange, the 45A's design includes a second woofer for an extended bass response and increased SPL (Sound Pressure Level) capability, The proprietary dual-suspension tweeter that creates the high top-end resolution is the result of six years of research and development by ATC Managing Director Billy Woodman and R&D Engineer Richard Newman.

• Mid-size very high performance active 3-way studio monitor

• Ideally suited to:

• Critical near-field listening applications in all control rooms

• LCR surround monitoring in medium control rooms

• Surround channels in medium-to-large contol rooms

• ATC hand built 6.5/164mm carbon-paper cone bass driver.

• ATC 25mm/1" Dual Suspension Super Tweeter

• Discrete MOSFET class A/B bi-amp pack with 150W/60W/25W continuous power output
