The four passive and two active loudspeaker systems in the ATC Entry Series are the first to employ ATC’s SH25-76 tweeter. Sharing technology with the renowned ATC Soft Dome midrange drive unit the new tweeter employs a unique dual suspension system suppressing diaphragm rocking modes even at high output levels.
Manufactured in house to exacting tolerances, ATC’s drive units are legendary for their many design innovations. For example, all voice coils are edgewise wound ribbon, OFHC (oxygen free high conductivity), copper wire operating in a precision machined magnetic gap. The magnet assembly also has a hole through the pole allowing air to be vented from under the dust cap reducing air flow noise at low frequencies and at the same time increasing power handling and reliability.
The Super Linear Technology found in the SCM19 model is equally ground-breaking. It has long been recognised that the detrimental effects of magnetic hysteresis is a significant factor in the production of distortion in loudspeaker drive units. With the clever use of revolutionary materials developed for the communications industry the problem has been solved for all time in the form of entry ATC’s SL drive units.They are unique not only in their ability to accurately reproduce piano but also in the precise manner they articulate the human voice.
