ATC SCS120 Pro: professional 15" studio subwoofer

ATC's SCS120 Pro is a 15" active subwoofer designed to deliver reference performance in the most demanding monitoring environments. Ideal for professional recording studios, it is designed for use with mid-field or main monitors and provides deep frequency extension, high dynamics and low distortion. Perfect for stereo, surround and Dolby Atmos setups.

Acoustic performance and extended response

Featuring the handcrafted ATC SS75-375SC driver, the SCS120 Pro provides an optimal balance of high SPLs, low distortion, and extended frequency response down to 20 Hz. Low-pass filter options include 50Hz, 65Hz, 80Hz and 320Hz, with 24 dB/oct Linkwitz-Riley slope.

Quality analog amplification

The amplifier module is based on 300W Class AB MOSFET circuitry, convection cooled and with active DC offset and overtemperature protections. It includes an active analog limiter to handle dynamic peaks musically.

Advanced controls and connectivity

The rear panel integrates balanced XLR inputs, link outputs, and controls for level, phase (0-180°), polarity, and gain (+6/+10dB). A 1/4" jack socket allows remote muting via optional footswitch. The low-pass filter is selectable from four frequencies, ideal for precise integration with your monitoring system.

Rugged construction and size

Built entirely in England with the utmost care, the cabinet is designed for structural rigidity and low resonance. Weighing 44.5 kg and generously sized, it fits perfectly in large professional studios.
