High-performance ATC Soffit-mount Subwoofer

The ATC SCS240iW Pro is a high-performance, dual 15-inch active subwoofer designed for soffit mounting in large control rooms. A perfect complement to ATC’s SCM200AiW Pro main monitor, the SCS240iW Pro shares the same cabinet width, providing flush in-wall installations with a clean, integrated look. It also pairs well with smaller full-range monitors in applications that require extended low end and high SPLs. Each SCS240iW Pro ships with two single-channel 7U, 19-inch rackmount amplifiers, connections to which are supplied via NL4 and 5-pin XLR. The SCS240iW Pro boasts ATC’s industry-acclaimed audio quality through advanced engineering and premium proprietary components.

Proprietary drivers with hand-wound voice coils

Great-sounding monitors start with great-sounding drivers. The SCS240iW Pro’s drivers are designed and manufactured to stringent tolerances at ATC’s in-house facility, where hand-wound voice coils are made from flat oxygen-free copper wire and operate in a precision long magnetic gap. Specially designed magnet vents not only reduce air flow noise and heat, but also increase power handling and reliability. ATC’s proprietary drivers are engineered to perform at exacting professional standards and deliver smooth, even frequency response without built-in EQ. In the SCS240iW Pro, the custom drivers have been painstakingly integrated into an acoustic suspension (sealed) cabinet to deliver consistent low-frequency performance in surface-mount installations.

A legacy of monitoring accuracy

A young engineer named Billy Woodman spent his formative years working alongside some of the best speaker engineers of the day. In 1974, Woodman founded ATC (Acoustic Transducer Company). Since then, ATC has focused on one thing: creating the most accurate monitor loudspeakers possible. If you want to make great-sounding recordings that translate to the world outside your studio, accurate monitoring is a must. You need to hear every nuance of your audio, exactly as it was recorded and mixed. ATC monitoring equipment, expertly engineered with the highest-grade components, is designed to provide just that. How good are ATC monitors? Just ask renowned producers and engineers like George Massenburg, Chuck Ainlay, Nathaniel Kunkel, and Doug Sax. You’ll also find ATC monitors in Abbey Road Studios, Sony Studios New York, Blackbird Studios Nashville, and many more world-class facilities. Sweetwater is proud to offer you ATC’s extensive range of professional studio monitors.
