Yet another vote for ATC. Prior to the active ATC SCM50ASLT speakers in my main listening room, I had Legacy Focus XD speakers. These ATC speakers are about half the size of the XDs, don’t require power amps (I didn’t like running the XDs full range active), sound better and actually play much louder (way beyond what is safe for my hearing) without distortion.
I’m equally impressed with ATC’s SCM20ASL pro active monitors in my recording studio.
I’m a classic rock keyboard and bass player. Although I enjoy all genres of music, my first love is classic rock.
Finally, I want to point out that passive ATC SCM40 speakers won the Arizona Audio Video Speaker Fest in 2019 against seven other mostly more expensive, highly regarded speakers. The presenter was not playing the normal audiophile music but mostly classic rock. Towards the end, some of the attendees wanted the volume really cranked up. The SCM40s filled the large room with clean, undistorted sound without breathing hard. They were driven with ATC’s P1 stereo amp (100W/channel).
