Know before you buy
Yes. Because these speakers feature a sealed cabinet design rather than a bass reflex port, they are less prone to low-frequency boom, making them an excellent choice for smaller rooms where placement near a wall is necessary.
With a sensitivity of 85 dB, these speakers perform best with a high-quality, stable amplifier that can provide sufficient current. While they are versatile, they thrive when paired with an amplifier capable of driving their 8-ohm mid-bass load effectively.
ATC’s proprietary 'SL' motor technology significantly reduces distortion in the motor system, particularly in the lower-mid frequencies. This results in a cleaner, more transparent sound that remains accurate even at higher volumes.
Yes, the SCM20PSL includes bi-wire inputs, allowing you to connect the high-frequency and mid-bass sections of the crossover separately if your amplifier and cable configuration support it.
Despite their compact size, they are engineered for professional-grade performance and can reach a peak SPL of 114 dB. They maintain composure and clarity even when pushed, thanks to their robust, hand-built driver construction.
The 6-year warranty covers manufacturing defects and component failure under normal use. It reflects ATC’s confidence in the longevity and build quality of their hand-assembled components.
