Proprietary ATC 25mm/1' Dual Suspension Super TweeterĪTC hand built 3'/75mm Soft Dome mid-range driver.Ģ x ATC hand built 6.5'/164mm carbon-paper cone bass drivers. All of the drive units are powered by ATC's proprietary active amp pack, a three-channel discrete MOSFET class A/B design with 150/60/25 for the bass/mid/HF respectively. The mid-range driver is ATC's hand-built three-inch soft dome and two 6.5-inch bass drivers that deal with the lower frequencies. The ATC SCM45A uses ATC's new one-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 Billy Woodman, managing director and Richard Newman, R&D engineer. The SCM45A is thus ideal as a center speaker between other SCM45A or ATC SCM50ASLs. In addition, the SCM45A is physically symmetrical (not mirror imaged) and sized for placement on a meter bridge. In contrast to the SCM25A, the SCM45A 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. Like the SCM25A, the new SCM45A is an active three-way with an unprecedented linear response across the critical mid-range, as well as across the rest of the audible range.

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, has high output and extended low frequency for its size but without compromising the overall balance for which ATC is so well known. The SCM45A is a completely new design but shares many features with the highly-successful SCM25A. *** Demo system present in our demoroom (not for sale) ***
