@immatthewj What you think and the reality of metal dudes are two different things or maybe many different things. My best friend for years (Earl Root, RIP) pretty well founded the metal scene here in the Twin Cities so I’ve been to a lot of metal shows of all sorts.
An SET with high efficiency speakers would probably be quite pleasing to them if there were subs as well (most high efficiency speakers trade off efficiency for LF bandwidth unless the bass horn is very very large; most people don’t have room for that) because such can play quite loud. They aren’t interested in pissing off the neighbors because Bad Things happen; that’s different from someone being simply inconsiderate.
Earl owned our amps and preamp with Snell B loudspeakers right to his death.
Most of the people I’ve met in metal bands (a few of which I’ve opened for) were really nice. If you didn’t see their stage get up, you’d never know they played in a metal band. Earl told me that for the most part all metal is theater, so if you’re not laughing a lot and having a good time you probably don’t get it.
Earl also told me (he ran a record store; that is how I first met him) that the metal guys preferred vinyl because it could get the cymbals right. So he was careful to pick up the LP releases for his store whenever possible.
So what you’re saying doesn’t jive with how they define ’more musical’ IME...
