Product Description
Engineered to support ATC's larger mid-field and main monitors, the SCS120 Pro 15" active subwoofer delivers exceptional low-frequency extension, expanded dynamic range, and seamless integration for stereo, surround, and immersive formats including Dolby Atmos. Thanks to employing advanced transducer and amplifier technology, the SCS120 Pro sub offers increased dynamic range and low frequency extension, strengthening the upper range of ATC's Professional Product line. The ATC Loudspeakers SCS120iW Pro (in-wall) variant offers all the above-mentioned performance but is optimized for flush in-wall mounting, featuring a shallower cabinet, and recessed rear input connector panel, maximizing floor space. The accompanying R1-300 Pro remote-mounted 7U/19” amplifier offers the user the flexibility to install the amplifier in a suitable wall close to the subwoofer, in a control room rack, or in a machine room, with connections made via NL4 speaker and 5-pin XLR cables.
HAND-BUILT 15" DRIVER
Building on the success of the 12" SCS70 Pro the SCS120 Pro features a hand-built 15"/375mm sub-bass driver, developed and manufactured by ATC at their facility in Gloucestershire, England. All driver components and parameters – from the drive system to the suspension – have been precisely optimized using the latest analysis tools available, at both small and large signal level. The result is an advanced transducer that combines a powerful short-coil motor system featuring optimized airflow and cooling, with a carbon-paper composite cone, resulting in deep, clean bass from 120 Hz down to below 20 Hz — with minimal distortion and maximum impact.
CLEAN AND CLEAR LOW END EXTENSION
The SCS120 Pro subwoofers deliver an extended low-frequency response without complex electronic equalization or processing, instead employing the more elegant combination of exceptional transducer engineering and a marginally larger cabinet volume. Such simplicity reduces phase shift and group delay, aiding the integration of the sub with the partnering monitor loudspeakers. Ultimately, it delivers a more balanced and coherent experience for the listener, combining an extending low-frequency response with outstanding clarity in the upper bass.
ADVANCED FEATURE SET
The SCS120 Pro is powered by a 300W Class AB amplifier, hand-built and optimized for fast, dynamic response. Versatile connectivity and control includes balanced stereo inputs, balanced (full-range) outputs, and analog 4th order Linkwitz-Riley filters with multiple crossover options — including an industry-standard 80 Hz setting and bypass setting for external processing. A polarity switch, variable phase control, and stepped attenuator allow precise system tuning. For added convenience, the amp features mute control via footswitch, with daisy-chain capability for linking multiple subs.
EXPAND YOUR SETUP
The SCS120 Pro is the perfect match for the ATC SCM100/110/150A Pro studio monitors and scales effortlessly to larger systems featuring the SCM200/300A Pro main monitors. Multiple subs can be employed to elevate performance and to fill larger rooms. Surround and Immersive Audio formats such as Dolby Atmos can be demanding of subwoofers, and these two new designs both offer significant performance gains over the smaller ATC SCS70 and the outgoing SCM0.1/15.
