SCM25A Pro
Designed for positioning on a meter bridge, or rack-mountable for broadcast applications, the ATC SCM25A Pro offers very high-performance in the most compact possible form factor.
The SCM25A Pro incorporates ATC's proprietary short coil seven-inch carbon-paper woofer, a 3" soft dome midrange driver and a one-inch silk dome tweeter in a ported enclosure that measures 10.4" (264 mm) (H) x 16.9" (430 mm) (W) x 16" (408 mm) (D). The integrated tri-amplifier generates 150 W RMS for the woofer, 50 W RMS for the midrange and 25 W RMS for the tweeter. The passively cooled amp pack also features FET limiting. The crossovers are all 4th order, critically damped with phase compensation.
The SCM25A Pro produces a wide, stable soundfield with very low coloration and offers low frequency extension to 42 Hz (-6dB).
