ATC SCM25A PRO MK2 - Compact Three-Way Active Monitor Speaker (Pair) - B-Stock

This is a B-Stock product that has been demoed at our showroom but is in excellent condition. There are some light marks from coming on and off the monitor stands, but nothing substantial.

The ATC SCM25A Mk2 is a compact 3-way active monitor designed for nearfield monitoring applications where critical listening is required. The SCM25A MK2 is based around s 6.5" bass driver, with a ATC 3" mid-driver and an ATC SH25-76S 1" soft dome tweeter delivering extended bass response and exceptional mid-range clarity. 

The 3-way monitor features proprietary drive units designed and manufactured by ATC. Low frequencies below 380Hz are handled by a 6.5”/164mm bass driver, mid-range frequencies between 380Hz & 3.5kHz by the ATC 3”/75mm soft dome mid-driver. High frequencies above 3.5kHz are handled by ATC’s SH25-76S Dual-Suspension 1”/25mm soft dome tweeter. This HF driver update is the primary improvement from the Mk1-to-Mk2 model. The enclosure is a ported/vented type, tuned to 32Hz and featuring a 3”/75mm diameter port with flared entry & exit to minimise port air noise.

The SCM25A Pro Mk2 is actively driven by a 3-way class A/B amp pack mounted in the rear of the cabinet. Each drive unit has its own dedicated power amplifier. Audio input is via a rear panel mounted 3-pin female XLR and power via an IEC mains power inlet. There are user controls for input sensitivity and bass ‘boost’. Crossovers are 4th order Linkwitz-Riley and all-pass filters are included to optimise the phase response through the crossover regions, improving the tonal accuracy, imaging, on and off-axis frequency response. FET peak limiters are included to reduce amplifier ‘hard-clipping’. Power ‘on’ and limiter ‘active’ is indicated by a front panel mounted bi-colour LED.

Key Features

  • 3-way design featuring ATC SM75-150 Soft Dome mid-range driver.
  • Wide dispersion vs frequency for excellent stereo imaging over a large listening area.
  • ATC discrete MOSFET class A/B amp-pack delivers high dynamic range in combination with very
  • low distortion and an extended HF bandwidth.
  • 4th order active crossovers with all-pass phase compensation ensure outstanding driver
  • integration.
  • Input sensitivity and bass ‘lift’ user controls.
  • Hand-built in England and covered by a 6-year warranty.
