I am on a somewhat tight budget, thinkign of going for with the m22's for the front, vp100 for the center, and have an Athena P2 sub. My questions is for the surrounds. Would I miss much and be totally disappointed with the QS4's compared to the QS8's? Should I go with a pair of somethign like M3's instead?

This is an apartment system, so it cant be monsterously loud, and I am guessing the room is around 250-300 sq ft.

Thanks for the advice!
