Summary:
I have a pair of the ATC active 100asl, They have there ownn built in amplifiersthe woofers are driven with there own 200 watt class a amp the midrange uses 100
watts and the tweeter uses 50 watts. thees speakers are produced in England ,and
designed by Billy Woodman The ATC can use any decent pre -amp but they do much better with a pre-amp that has balanced lines I have heard a lot of products in the past , but the ATC 100asl a the pace ,rythum and timing that I love .Another thing is that they can play very loud. Dont get me wrong on a quite passage they whisper and on a loud passage they can knock you out of your seat. Having a tri-amped system simply is much better than a passive one. If any of you good folks
get a chance to here the ATC active speakers it will be a treat that you will not forget
