Product Infomation  
As multi-channel systems increase in popularity, it is easy to forget that the basic stereo pair of speakers at the front of the listening area remains an essential element. Existing libraries of recorded music, the commitment of recording companies to stereo in its current form and the new high resolution digital two-channel formats indicate that stereo will continue to be the main source of recorded music for the foreseeable future. For these reasons ATC still regards the main stereo speaker pair as the foundation on which a high performance multi-channel system can be built. What better way to establish that foundation than by choosing the immensely powerful and highly dynamic SCM100 ASL three-way active monitor. The SCM100 ASL (active) and SCM100 SL (passive) are designed to perform at their best with the finest quality hi-fi equipment. Like their smaller brother, the SCM50 ASL, 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 an upgraded tweeter and enhanced port profile have brought about further improvements in all perform-ance 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 MOS-FET 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. In passive form, the SCM100 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the audio frequency range.
