ATC SCM40A speakers redefine entry-level hi-fi with active design, integrating amplification for precise control over sound. Featuring ATC's acclaimed drive units, they deliver immersive audio with remarkable clarity and depth. Perfect for enthusiasts craving premium sound without the complexity of separate amplifiers.

Manufactured in-house to exact tolerances, ATC’s drivers are legendary for their many design innovations. For instance, our hand-wound short voice coils use only high-density edge-wound flat OFC wire and operate in a precision long magnetic gap. Front and rear magnetic venting not only reduces airflow and noise but increases power handling and long-term reliability. Meanwhile, massive motor assemblies offer no-compromise optimization for each voice coil diameter.

The unique ‘Soft Dome’ technology was developed by ATC in 1976. Its arrival revolutionized professional studio monitoring. Remarkably today, as then, it remains the only mid-range device capable of giving ultimate performance.

Built to give a lifetime of service and musical enjoyment, all ATC products carry a six year Manufacturer's Warranty.
