Product Description

The SMC45A Pro is a mid-sized three-way active loudspeaker, which can be used for both near- or mid-field positions. It shares a number of the same features of the SMC25A Pro, whilst filling the gap in ATC’s professional active monitoring loudspeaker range.

The SMC45A Pro design includes a second woofer for deeper bass response and increased SPL (Sound Pressure Level) capability, combined with a new proprietary dual-suspension tweeter for top-end resolution.

Key Features:

• 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 ‘S-Spec’ Tweeter
• Discrete MOSFET class A/B tri-amp pack with 150W/60W/25W
• continuous power output
