Best value minisystem for hardrock/metal?

Maybe some old Klipsch or JBL??? You might have to spend a few more bucks to get what you are looking for.

Steuspeed is right. Get an efficent speaker that you can power with most anything. It won't sound good in absolute terms but it will get loud and sound better than the Audiovox mini system the guy down the street has. Speakers that are 96dB+ efficent should work well.

Good luck!

The guy isnt looking for speakers..he's looking for a mini-system.
I would go to 'best buy' or 'circuit city'and see what they have in your price range.
30 day return policy so you can audition a few systems until you find one you like.
