I am interested in a Polk PSW505 sub and I am wondering if this sub is good for loud music. I listen to a lot of techno at loud volumes. I have read reviews and most of them came back positive except some I read said that the drivers will fry after 5 minutes after playing it loudly. I am sorta new to this tech stuff so please keep it simple.What are some safe settings to put it at and will it shake my room at the recommended setting? One last thing, how do i break in a sub?
