I'm your huckleberry. I listen to a fair amount of metal and hard rock.
I've owned Golden Ears - they are OK. Bass not bad, but I found they lacked that "snap" that a lot of metal fans dig.
Without going through everything I've owned/tried... my short list.
Ohm Walsh - They can thump, they sound huge, they gobble power. I'm using some ancient SSC's, actually had the tweeters start smoking (pushed an absurd amount of power through them and they are OLD... they still kept ticking). I'm going to be demoing newer ones. I really dig everything about them for the price. But, set-up is different. You want the speaker end to be "live", the back end to be a bit more dead. I'm really looking forward to demoing the newer Ohm's.
Klipsch - Older CF3's/4's (but they are hard to find, and hard to get parts for). Conversely the KLF 30's (and lots of fun upgrades out there for them ). I have a pair of these on the way I picked up used. Chorus II's are a damn fine metal speaker.
JBL - If you want to drop some cash - the 4367's do a great job, the M2's and the crown amps can be had for the 11-12k range. DAMN good speakers.
Tekton - The Double Impacts are pretty darn nice for the cash, dynamic, live sounding. I've heard the SE's, better, but not sure they are worth the upgrade. My fear - all those tweeters.
NHT 3.3's - used. Full range, can thump, can be a bit bright and have a funky set-up. But a good speaker.
IF you want something more refined. The DynAudio Contour 60's - can thump, and can play loud without an issue. That said, the soundstage isn't quite as big, they also don't sound as "live" as the Ohm's, Klipsch, or JBL
You may be tempted with Klipsch to try the Palladiums - I did. I wouldn't get them for metal. Too lean in the bass, to bright up high. I had the P37's. Good speaker, but too lean.
Focal - forget it. Too bright, too lean for a given size.
Used Wilsons - might do the job nicely depending on model and how you feel about the focal tweeters. The new wilsons with the softdomes are pretty nice.
Golden Ear - I have mixed thoughts. They thump, they are not bright, they throw a big soundstage for the most part. But I just didn't love the midrange.
Don't get caught up in the price. More expensive doesn't always mean you will like them better, even though they may "measure" better.
