So I've had my axioms for just over a week now and am extremely happy with them. But since I am still in the trial stage am thinking about upgrading my EP175 to an EP350. From the posts I've seen about them I am about 95% sure I'm going to upgrade my QS4's to QS8's. Thoughts??.... Room is only 16x11x7.5 sq.ft. Maybe the sub might be overkill??

Oh Upgrade-itis will you ever stop?
