ATC has announced the free-standing SCS120 Pro and flush in-wall mounting SCS120iW Pro as new flagship subwoofers for low-frequency extension, expanded dynamic range, and integration for stereo, surround, and immersive formats including Dolby Atmos.
The new models follow the free-standing SCS70 Pro and flush in-wall mounting SCS70iW Pro 12-inch/300mm active subwoofers, but both feature a new hand-built 15-inch/375mm sub-bass driver, developed and manufactured by ATC at its facility in the UK. All driver components – from the drive system to the suspension – were designed using the latest analysis tools available at both small and large signal level. The transducer combines a powerful short-coil motor system featuring optimised airflow and cooling with a carbon-paper composite cone, and deliver bass from 120Hz to below 20Hz.
Both models avoid the use of electronic equalisation or processing, instead employing a combination of refined transducer engineering and a marginally larger cabinet volume to reduce phase shift and group delay.
Both are powered by a hand-built 300W class-A/B amplifier for fast, dynamic response. Adaptable connectivity and control includes balanced stereo inputs, balanced (full-range) outputs, and analogue fourth-order Linkwitz-Riley filters with multiple crossover options – including an industry-standard 80Hz setting and bypass setting for external processing. A polarity switch, variable phase control and stepped attenuator allow precise system tuning. The amplifier also features mute control via a footswitch, with daisy-chain capability for multiple subs.
The SCS120iW Pro (in-wall) variant offers all the above, but is intended for flush in-wall mounting courtesy of a shallower cabinet and recessed rear input connector panel that maximises floor space. An accompanying R1-300 Pro remote-mounted 7U-high, 19-inch amplifier allows flexible installation in a suitable wall close to the subwoofer, in a control room rack, or machine room, with connections made via NL4 speaker and 5-pin XLR cables.
The subwoofers pair with the SCM100ASL Pro, SCM110ASL Pro, and SCM150ASL Pro studio monitors, and also scale to larger systems with SCM200ASL Pro and SCM300ASL Pro main monitors. Multiple subs can be employed for larger rooms.
SCS120 Pro and subs are respectively available at an RRP (Recommended Retail Price) of £4,575 (exc VAT) and £5,408 (exc VAT) including the R1-300 Pro remote (SCS120iW Pro).
