ATC has developed two new centre channel speakers for multi-channel system applications. Available in two sizes and emulating their SCM7 and SCM11 loudspeaker counterparts, the new C1C and C3C designs “will deliver dynamic wide-bandwidth accuracy and outstanding vocal intelligibility”.
Matching the monitors, the C1C and C3C driver systems feature ATC’s SH25-76 dual-suspension tweeter that’s designed and built in-house.
Designed for performance
The tweeter’s 15,000 gauss (1.5 tesla) neodymium magnet has a black heat-treated top plate. This dissipates heat away from the voice coil to maintain high power handling and low power compression.
A precision-machined 5.5mm rigid alloy waveguide provides optimum dispersion, a flat on-axis frequency response and resonance-free operation.
In each centre-channel system the tweeter sits between two mid-bass drivers identical in design to those employed by the corresponding L/R main loudspeaker.
The C1C utilises the 125mm ATC mid/bass driver of the SCM7. This comprises of a 45mm soft dome and a huge 3.5kg high-energy magnet system. You also get a 45mm ribbon wire voice coil, milled and formed by ATC.
The new C3C design uses the SCM11’s CLD 150mm mid-bass driver incorporating a 45mm soft dome. Exclusive to ATC, Constrained Layer Damping offers reduced harmonic distortion between 300Hz and 3 kHz, an extended frequency response and improved off-axis performance.
ATC’s new 5.1 channel systems
Two new compact ATC 5.1 channel speaker systems add the SCM7, SCM11 and ATC ‘C1 sub’ active subwoofer to the aforementioned speakers.
The C1 System comprises four SCM7s, the C1C, and the C1 Sub.
The C3 system unites the C3C with SCM11s in the front, and the SCM7s in the surround positions.
