ATC SCM19A Active Floorstanding Speakers (Pair)

At the heart of the SCM19A is ATC's renowned 150mm Super Linear (SL) mid/bass driver, featuring a 75mm integral soft dome and a substantial 9kg optimized short-coil, long-gap motor assembly. Paired with ATC's 25mm dual-suspension soft dome tweeter and precision alloy waveguide, the result is a loudspeaker capable of reproducing music with remarkable clarity, coherence, and dynamic expression.

Unlike conventional passive loudspeakers, the SCM19A incorporates a dedicated 182-watt Class A/B bi-amplifier within each speaker, providing 150 watts to the mid/bass driver and 32 watts to the tweeter. Combined with ATC's active crossover filters and phase compensation circuitry, this approach delivers greater control, lower distortion, and improved driver integration across the entire frequency range.

The sealed cabinet design contributes to the SCM19A's characteristically tight, accurate bass response while preserving the timing, tonal balance, and midrange transparency for which ATC loudspeakers are known. Vocals sound natural and lifelike, instruments occupy clearly defined positions within the soundstage, and complex musical passages are reproduced with exceptional composure and realism.

For audiophiles seeking the benefits of active loudspeaker design in a refined floorstanding form factor, the SCM19A offers a streamlined path to reference-quality performance, combining ATC's professional monitoring heritage with elegant British craftsmanship.
