As some one who has been into this hobby for 20 years and started out listening to metal (still go some times) you need to stay away from razor flat speakers, Revel and Thiel are good examples. They sound good when the music has bass recorded in but button up quick when the recording sucks.
I have always liked Wilson Audio and B&W for metal. Their flaws of over done bass thumb (upper bass 80-100hz) lends itself well to hard rock heavy metal. Older models of both brands can be bright so stick with newer ones (sophia 3,sasha or later, 802diamonds).
You can always add subs and a good digital highpass but that is not cheap if done right.
