"1(Fast deep Bass, however not too over powering or boomy
2)Treble smooth and accurate that defines the lead guitars accurately without a brash blur of distortion.
3)Treble that lays the drummers symbols on top nicely to the rest of rhythm
4)A midrange that gives the vocals a clean but not harsh edge.
5)Good separation of the different instruments playing in the music
6)Good live sound, if you know what I mean."
You've already purchased your speakers, but for future reference, consider some Tekton speakers. I've owned a few of the speakers mentioned in this thread. Polk, Paradigm (Signature Series), JBL, Usher Dancers and a couple of others, all with the purpose of playing loud, hard rock. More recently I bought some Tekton loudspeakers and as much as I try to find fault with them (just my nature I guess), it's difficult to do. The characteristics you mentioned are all met by these speakers. The Double Impact or Double Impact SE will rock your socks off.
