ATCs are great. However, it is very picky on amps. If you don't have a good amp then you'll never get the best out of ATC. As far as bass goes on the ATC, while it has one of the best mid bass, the SCM10s I have sounded much deeper than many floor standing speakers we have compared to. What does it mean? it goes back to amplification.
Sometimes it might be easier just to get active speakers from ATC.
