Dual 15″ in-wall active studio subwoofer
The ATC SCS240iW Pro is a high-performance active subwoofer with twin 15″ drivers, for in-wall (soffit) installation in large control rooms. It pairs with in-wall SCM300AiW Pro for stereo, multichannel and immersive systems, and also complements smaller monitors where extended bass and high SPL are required.
Twin 15″ drivers for large control rooms
With twin 375 mm drivers and two 300 W amplifiers, the SCS240iW Pro reaches 116 dB continuous, 121 dB peak and extends to 22 Hz. It is designed for large control rooms and Dolby Atmos systems, where the low end needs energy without distortion.
Matches the main monitors
The cabinet width matches the SCM300AiW Pro, so subwoofer and main monitors can be installed together in the wall with a uniform look. The R1-300 amplifiers sit in a rack or on the wall, away from the cabinet, and cool without fans.
Hand-built in England
ATC hand-builds its drivers and amplifiers in Stroud, England, from voice-coil winding to the final test of every unit. That is why its subwoofers are covered by a 6-year warranty.
