Okay, I'm being glib, but... I believe the QS8's will go a bit lower than the QS4's (bigger cabinet, bigger drivers). Which, depending upon the bass management available through your receiver, could make a meaningful difference in how robust the surround channels sound.

But the real reason why I bought them was because I didn't want to wonder "what if...". I think they are the ultimate!
