What is the best HEAVY METAL speaker?


I know totally blasphemy question here on Audiogon. But you like what you like, right? Anyway, I know most metal music is totally compressed and recorded horrible (aka Metallica) however there is a new age of metal bands out there that are starting to change that (Opeth started with Blackwater Park). So what speakers out there can take the pounding of a double bass drum kit hitting at full throttle and give the roar of metal guitar justice. There has to be a set up that would make Glen Tipton turn his head and say hell ya!

@canibefrank  - You're welcome. Would love to actually hear a pair. Might be right up my alley too...

What do you think between jbl m2 active vs atc 50asl active towers + 2 subwoofers? Have any of you ever made such a comparison? I wonder which of the two systems would sound better and best render the magnitude and impact of the live sound of a hard rock\metal concert... What do you think?
