Yes, even though the 40s are fantastic, the 50s and 100s make a further significant jump in quality and if they fit with your budget are seriously worth considering. Given you like the tonal qualities of the 40s, you should have no worries buying the actives without hearing, as everything is tonally consistent.Dr Lodge said:These SCM40s are for keeps I think, its just a matter of settling on a price. I can see how these speakers could sound harsh in the treble but with my setup they are just wonderfully revealing. I really wonder what a pair of active SCM50 or SCM100s would sound like with their bigger bass units...one day perhaps
The pair on eBay look like they may not have the SL bass driver, so I would avoid those. 50s and 100s come up pretty regularly on eBay. There are some 100 Towers (which will be the design you prefer) on the classifieds of atcforums.co.uk here: http://atcforums.co.uk/viewtopic.php?f=29&t=3341 Feel free to join us there btw!
Re the treble on the 40s, it is good to know that soon there will be a retro-fittable proprietary ATC tweeter, hopefully before the end of the year
