I can confirm what others on this thread have said about ATC actives with regard to rock music. David Gilmour, Tom Petty, Lenny Kravitz and many rock artists use these speakers. However, the bass might be a little too tight and accurate for what rappers might prefer...
As for loudness levels, you can get night club music levels with an SCM 300 ASL without the harshness or compression you get from lesser quality "club" speakers....but you will also need a night club venue; an acoustically treated room and a large lot, far away from any neighbours.
I have the active SCM 100's at home with a 0.1/15 sub. I supect they would be ample enough for your described need. I don't do big dance parties, but after 25 years of collecting speakers, for the first time, I can enjoy music continuously and accurately at levels similar to live music with very little compression (heaps of headroom and dynamic range). I don't even need to drive them hard as it quickly gets too loud for my 25' by 20' room.
I have found the SCM 20's, as some have suggested, can get close to rock party/live loudness levels when driven hard in a small room. However, there is noticeably less dynamic range than the 100's; I think this setup would be flirting with driver damage in the passive version and I suspect the soft clipping circuit on the actives would often kick in, protecting the drivers but adding distortion. You would definitely need a sub as the lack of extreme LF bass is obvious at higher levels on some material.
SPL's on different tracks can vary widely, particularly with digital sources, what may be rock party optimum on one track might blow a driver or distort on another track. With an SCM 20 you probably would not enjoy the party, my guess is that you would be fretting over volume levels all the time just to keep it at the desired loudness without distortion/damage!
