But seriously folks...
I might recomend a good speaker, and an outboard equalizer.
Then carefully preset the eq so that you have the balance you want, but can still enjoy the speakers the rest of the time, with good recordings.
I think if you buy a speaker that will allow poorly mixed, poorly transferred rock, you will have such a poor product, it won't be worth owning. So outboard fix is the best way to go, IMHO.
