LAS VEGAS, NEVADA – APRIL 2026: TransAudio Group, the longtime U.S. distributor for ATC, is pleased to announce the release of ATC’s most powerful in-wall subwoofers to date – the SCS140iW Pro and SCS240iW Pro. Building on ATC’s acclaimed SCS70iW Pro and SCS120iW Pro designs, these new dual-driver models deliver significantly higher output and performance for today’s stereo, surround, and immersive studio environments.
Powerful Performance for Professional Studios
The SCS240iW Pro is designed for larger control rooms and immersive setups, engineered to pair seamlessly with ATC’s SCM300A main monitors. The SCS140iW Pro, meanwhile, matches the SCM200A and excels as a dedicated low-frequency effects (LFE) solution for formats such as Dolby Atmos®. Both models deliver extended low-frequency response, exceptional headroom, and accurate monitoring for demanding professional spaces.
SCS140iW Pro – Compact Power
Featuring dual 12-inch drivers and twin remote amplifiers, the SCS140iW Pro achieves 116 dB continuous SPL and 121 dB peak SPL at 1 meter – a 6 dB boost over the earlier SCS70iW Pro. Despite its higher output, the cabinet remains compact, visually matching the in wall SCM200AiW monitor. It’s ideal for systems needing deep, controlled bass with high output.
SCS240iW Pro – Maximum Output
The SCS240iW Pro uses dual 15-inch drivers and dual amplifiers to deliver 119 dB continuous SPL and 126 dB peak SPL at 1 meter – another 6 dB improvement over its predecessor. It perfectly aligns with the SCM300AiW in-wall monitor for full-range in-wall installations or can partner with other large ATC models such as the SCM150A Pro.
Advanced ATC Engineering
Both subwoofers feature in-house-built ATC drive units, each with a 30 mm magnetic gap – the longest ever from ATC – for reduced distortion and higher excursion. These innovations ensure deep, precise response from 120 Hz to below 20 Hz, maintaining low distortion and maximum accuracy.
Each subwoofer is powered by a pair of R1-300 Pro 300 W Class A-B amplifiers in a remote-mount 7U-rack format. The amplifiers provide flexible installation, multiple crossover options (including 80 Hz and bypass), polarity and phase adjustments, and mute control with daisy-chaining capability.
“These powerful in-wall subs are now available," noted Brad Lunde founder and president of TransAudio Group. “ATC continues to meet and exceed market demands for power, pure sound and flexibility.”
