The ATC SCM10A-2 is a two-way design that
incorporates a 5” mid/bass driver and a 1”
soft dome tweeter. The speaker’s dimensions
are 11.5” high by 9” wide by 12.25” deep. The
enclosure has a front to back tapered shape
and is composed of a special gray finished
laminate material. The speaker grill is made
of black perforated metal. The back of the
speaker is an aluminum extrusion which acts as
a heatsink for the power amplifiers output
stage transistors. The structure is very
rigid, non-resonant, and visually attractive.
Internally, the SCM10A-2 features the ATC
proprietary twin channel power amplifier with
the Grounded Source output stage and the
electronic crossover. The crossover is a
fourth-order Linkwitz-Riley which provides a
crossover frequency of 2.8 kHz and time
(phase) alignment. Frequencies above the
crossover frequency are sent to the 50 watt
class A power amplifier that drives the
tweeter and frequencies below are sent to the
200 watt class AB amplifier which drives the
mid/woofer. The mid/woofer is awesome. I have
never seen a 5” driver with such a massive
motor structure. This accounts for the low
distortion high output of the SCM10A-2.
Connections to the speaker are at the back as
one would expect. There is a female XLR for
the line level input signal. The signal can be
balanced or unbalanced. The input impedance is
10K ohms which is an easy load for solid-state
preamplifiers but might prove to be less than
optimum for some vacuum tube preamplifiers.
The AC power input is via an IEC connector
which sits next to the power switch.
