I’m stunned by their clarity, resolution, and definition across the audible band, but especially in their ability to reproduce accurate bass down to about 50 Hz.
… if truth is your goal, I haven’t experienced a better speaker to provide it than the Version 2 of ATC’s SCM 11.
For the money and putting my experience and word on the line the ATC SCM11 are at the absolute top of their class.
You really would have to spend much more to even be able to stand up confidently against these awesome little speakers let alone better them.
If I had the room for another pair of speakers I would have a pair in a heartbeat.
I would really struggle to name a single speaker that can get anywhere near such a stunning level of performance in that price range.
