If you have a sub, you can try budget PA speakers. The Behringer B212XL and B215XL, Mackie C200 and c300z are models that seem liked for home use. These are high efficiency compression horn speakers so can play loud without strain and are very dynamic. Low powered tube amps are enough to drive them. I have the B212XL and with a sub and bass EQ they sound impressive for around $300.00 a pair.
To me, pretty sounding expensive high-end speakers seem a waste for heavy metal music.
