What is the best HEAVY METAL speaker?

Another vote for CF 4 ....  I had a pair driven by B&K M200 Sonata mono amps.  It was ridiculous, their size was ridiculous too.  Replaced by a pair of KEF Reference 2 .... also rocked.  

"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.  

JBL Everest if you can afford them. 
I couldn’t, and my listening room wasn’t big enough anyway, but I bought a pair of JBL 4367s with a pair of JL Audio Fathom subs, and I’m very happy with the set up. 

Save money and get cerwin vega. Really good for this style of music imho. 

JBL, hands down....
