A COUSTIC

ENGINEERS

Manufactured in house to exacting tolerances, ATC’s drivers are legendary for their many design innovations.

For instance, our hand-wound short voice coils use only high density edge-wound flat OFC wire and operate in a

precision long magnetic gap. Front and rear magnetic venting not only reduces airflow and noise, but increases power

handling and long term reliability. Meanwhile, massive motor assemblies offer no-compromise optimisation

for each voice coil diameter.

The unique ‘Soft Dome’ technology that features in the mid driver of our SCM 40 floor-standing monitor

was developed by ATC in 1976. Its arrival revolutionised professional studio monitoring.

Remarkably today, as then, it remains the only mid-range device capable of giving ultimate performance.

The Super Linea Technology found in our SCM 19 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.

INTRODUCING

A NEW SERIES

OF HAND-BUILT

2- AND 3-WAY

P ASSIVE MONITORS

FROM ATC

With the clever use of revolutionary materials developed for the communications industry, the problem has been

solved for all time in the form of ATC’s SL drive units.They are unique not only in their ability to accurately

reproduce piano, but also the precise manner in which they articulate male voices.

This is hardly surprising given the reduction of third harmonic distortion 10-15 dB between 100Hz and 3kHz.

Constrained Layer Damping (CLD) is a new driver cone technology from ATC that has been integrated into the

SCM11 monitor and represents a step-change in driver-to-system performance and reproduction of music.

Advantages include reduced harmonic distortion between 300Hz and 3kHz compared to a conventional cone;

extended resonance frequency response (that eases constraints on cross-over filter slopes); and improvements

in off-axis response.

Built to give a lifetime of service and musical enjoyment, all ATC products carry a six year guarantee.
