Know before you buy
Being an active speaker means the ATC SCM19A has its own built-in 182-watt bi-amplifier and crossover filters. You do not need a separate power amplifier; you only need a pre-amplifier or a source with volume control to drive them.
The SCM19A exclusively uses XLR inputs, which are standard in professional audio environments. To connect RCA sources, you will need high-quality RCA-to-XLR cables or a pre-amplifier that features balanced XLR outputs.
Yes, their sealed cabinet design provides tight, controlled bass that avoids the 'boominess' often associated with ported speakers in smaller spaces. Their compact floorstanding footprint makes them an excellent choice for rooms where precise imaging is a priority.
The 'SL' (Super Linear) technology is designed to significantly reduce distortion in the motor system. This results in a cleaner, more accurate midrange and bass response that stays true to the original recording, even at higher volumes.
No, the system matching is already optimized by ATC. The internal 150W LF and 32W HF amplifiers are specifically calibrated to the drivers, ensuring the best possible performance without the guesswork of pairing separate components.
These speakers are known for a studio-monitor-like honesty. They prioritize natural voice reproduction, exceptional transparency, and a neutral presentation, making them ideal for listeners who prefer accuracy over colored or exaggerated sound.
