ATC - SCM50P SL - Classic Series 9" 3-Way Passive Speakers (Pair)
The SCM50P SL is designed to perform at its best in the recording studio or at home with the finest quality hi-fi equipment.
The monitors’ 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 the new ATC SH25-76S tweeter and enhanced port profile have brought about further improvements to all performance parameters.
Each drive unit in the active model has its own dedicated and individually matched MOS-FET amplifier, while the 234mm (9.21") bass driver incorporates ATC’s unique Super Linear Magnet technology. Our active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.
Like the HF, mid and bass drivers, all electronics are designed and manufactured in-house to create a no-compromise active system. In passive form, the SCM50 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the frequency range.
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.
