ATC – SCM100A SL – Classic Series 12″ 3-Way Active Speakers (Pair)

The SCM100 ASL is designed to perform at its best with the finest quality hi-fi equipment. Like its smaller brother, the SCM50 ASL, the monitor’s ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include an upgraded tweeter and enhanced port profile have brought about further improvements in all performance parameters.

Bass performance is equally impressive, thanks to ATC’s 12? professional level bass driver that incorporates the company’s unique Super Linear Magnet technology. Bass, mid and HF drive units in the active model have their own dedicated and individually matched MOSFET amplifiers.

ATC’s active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.

All of the Classic Series range are available as passive or active units. Passive units have an SL suffix and active units an ASL suffix. Passive monitors are equipped with a “tri-wire” connection panel to enable separate amplification of the bass, mid and high frequency drivers. Active units have a built in three way Amplifier with frequency, gain and phase correction which has been individually optimised at the ATC manufacturing facility. Adjustment of input sensitivity and bass boost are available to the user via controls on the rear panel of the unit.

It was the development of active loudspeakers that first brought ATC into electronics design and engineering. Active speakers demand multiple power amplifiers so ATC from the mid 1980s became not just a loudspeaker manufacturing company but an electronics manufacturer too.The further step from electronics for active speakers to a range of stand-alone amplifier products was natural and now means that ATC engineering is available from the recording desk or CD player output to the ears.

The difficulty inherent in designing such loudspeakers is one of scale. Hi-fi levels of accuracy and detail call for lightweight moving parts and delicate engineering. Professional monitor levels of performance however demand far more robust components engineered to survive the rigours of high level use for extended periods.The only way to combine the two is through precision engineering of a class and scale more often associated with aerospace or motorsport. But the results are worth the effort and the cost. ATC loudspeakers, with their unique in-house designed drivers, combine the best of hi-fi and professional to devastating effect.

Speakers are supplied with stands and fabric wrapped grills.
