Gloustershire, UK (September 8, 2014)—British loudspeaker manufacturer ATC has introduced two new reference nearfield monitors—the active SCM20ASL Pro (V2) and passive SCM20PSL Pro.

Both models feature ATC’s drive units, hand-built in its UK facility. The new SH-25-76S 25mm/one-inch soft dome tweeter, the first to be designed and built by ATC, is the result of six years of research and development by managing director Billy Woodman and R&D engineer Richard Newman.

“The design takes notes from the ATC midrange dome by utilizing a dual-suspension design, negating the requirement for Ferro-fluid, and avoiding the detrimental effects of this drying out over time, a feature considered to be of utmost importance for long term consistency,” said Woodman. The neodymium motor with heat-treated top plate reportedly provides extended frequency response (-6 dB @ 26 kHz) and low non-linear distortion. The geometry of the waveguide is designed for optimum dispersion and made from a precision-machined alloy.

The bass/mid driver used in both loudspeakers is ATC’s proprietary 150 mm/six-inch Super Linear device, constructed with a 75 mm/three-inch voice coil and a short-coil, long-gap topology.

The electronics in the active design have also been designed with an aim to reduced noise and distortion (a further -10 dB at 10 kHz) and operating temperature. The amplifier design is a revised version of ATC’s discrete MOSFET Class A/B design with 200W and 50W continuous power available for the bass and high frequency sections, respectively.
