One important thing about the MK442s is that they have a fairly narrow vertical dispersion so if you are going to use them as the front three, make sure the tweeter is aimed at your ears. You will really want the tweeter to be level with your ear height at your listening position. They are not hugely sensitive, so if you want to blow your windows out with heavy metal music, they aren't a great choice. However, if you are more interested in a decent level of fidelity at moderate listening levels for a low price, they are a great choice.
