ATC Loudspeakers made a memorable impact at Axpona 2025 with the world premiere of the SCM20ASL 2-Way Stand-Mount Active Loudspeakers. The debut drew an enthusiastic crowd of audiophile press and industry insiders eager to experience the brand’s latest innovation.
The unveiling event was hosted by Lone Mountain Audio, ATC’s U.S. distributor, who warmly welcomed attendees with a classic British breakfast, featuring all the traditional favorites—a nod to ATC’s UK heritage and commitment to timeless quality. ATC audio engineers Rich Newman and Cal Shackleford were on hand from Stroud, England for the unveiling event.
The room stayed packed throughout the show, buzzing with nonstop energy as word of the debut quickly spread through the Axpona show halls. The SCM20ASL’s powerful performance and precision engineering kept listeners engaged and impressed, setting a strong tone for the weekend.
The most compact active speaker in the ATC line and based on the 50th anniversary ‘Limited Edition’ design, the SCM20ASL is the ideal choice for modestly sized rooms where outstanding musical reproduction is the goal.
The 2-way SCM20ASL continues ATC’s philosophy of combining the best in-house drive units with matched on-board amplification for optimal fidelity. Uniting the benefits of compact size and wider bandwidth with the improved phase coherence, response speed and dynamics of ATC active operation, the SCM20ASL is perfected for small to medium sized listening environments. In addition, its sealed cabinet design ensures exceptionally well controlled bass even in smaller spaces and/or when located close to walls.
