ATC has developed two new centre channel speakers for multi-channel system applications. Available in two sizes and emulating their successful Entry Series SCM7 and SCM11 loudspeaker counterparts, the new C3C (V.3) design will deliver dynamic wide-bandwidth accuracy and outstanding vocal intelligibility at the centre of compact 5.1 channel ATC systems for audiophile film and music devotees.
Matching the monitors, the C3C driver system feature ATCs acclaimed SH25-76 dual-suspension tweeter, designed and built in-house according to the brands rigorous low-compromise regimen for exceptionally low distortion and an extended high frequency response. The tweeters 15,000 gauss (1.5 tesla) neodymium magnet has a black heat-treated top plate, which 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.
Compatible Mid-Bass Drivers
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 new C3C design uses the SCM11s 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.
The new C1C system incorporate new crossovers developed from the SCM7 and SCM11 designs, involving metallised polypropylene capacitors, large air cored inductors and ceramic wire-round resistors to offer superior power handling and clarity. Consequently, and in common with the SCM7 and SCM11, the centre-channel systems exhibit an impedance curve free from low values and extreme phase angles, presenting an easy load for amplifiers of 75 to 300 watts.
