There is quite a few good choices out there and non which I (or someone else ) might recommend will guaranty the perfect synergy with your gear, preferences or esthetics. Considering your music preferences (which is not to far from my own) I would say Zu and WLM. Single driver designs might prove locking for "Hard Rock" aficionados.

Omega, Rethem Saadhana (used) or Sachiko are all great ....... actually, they are quite awesome but not the headbangers' dream IMO. I love the Sachikos which I am building right now.........yes even for Rock ("The Wall" sounds just scary) but they aren't the most accommodating when it comes to size and Wife Acceptance Factor (WAF) is not very high.
My wife is OK with my own cosmetic modifications but would not approve the original Sachiko design.

As to Zu and WLM. These are on the opposite side of the spectrum - Zu, sounds like live performance from the 5th row seat while WLM are a bit more laid back and smooth.
Choose you poisson wisely
