British loudspeaker manufacturer ATC, led by Billy Woodman, introduced the ATC SCM45A ($11,490 MAP) reference monitors at Winter NAMM 2015. The company states that the ATC SCM45A monitors will be in stock and ready to ship on February 1, 2015.
The SCM45A is a completely new design but shares many features with the highly successful SCM25A. It fills a gap in ATC’s product range for a mid-size three-way that can be used in near- or mid-field positions. It has high output and extended low frequency for its size, without compromising the overall balance for which ATC is known.
Like the SCM25A, the new SCM45A is an active three-way with what ATC describes as an unprecedented linear response across the critical mid-range, as well as across the rest of the audible range. In contrast to the SCM25A, the SCM45A has a second woofer for deeper bass response and increased SPL capability, as well as ATC’s new proprietary dual-suspension tweeter for increased resolution in the top-end. In addition, the SCM45A is physically symmetrical (not mirror imaged) and sized for placement on a meter bridge. The SCM45A can be used as a center speaker between other SCM45A monitors or ATC SCM50ASLs.
The ATC SCM45A uses ATC’s new 1-inch dual-suspension “Super” tweeter, the first to be designed and built by the company and the result of six years of research and design by managing director Billy Woodman and R&D engineer Richard Newman. The midrange driver is ATC’s hand-built 3-inch soft dome; two 6.5-inch bass drivers handle the lower frequencies. All of the drive units are powered by ATC’s proprietary active amp pack, a 3-channel discrete MOSFET Class-A/B design with 150/60/25 for the bass/midrange/HF, respectively.
