OK, I am hurting on a decision here....I'm completely torn...I'm losing sleep!!! (ok, not really....but it's a tough decision and I need some resident audioholics to help me with what they perceive to be the better way to go.) I want to upgrade my left and right speakers - currently I am using the Polk Audio RM6750 speakers and I've been very happy with them. But now it's time to grow. So here are my options: The BIC America Venturi Series DV64 Floor Towers Or the Polk Audio 2-Way Monitor Series 50 Floor Towers Ok, guys...please, edu-macate me! :D
