I'm trying to find a new set of L/R speakers that are small so that when I go to college they'll fit in my dorm room. I currently have a Procenter100 and two Procinema80's at the back and A/D/S towers up front with a Velodyne CT120 sub all being powered by an Onkyo 797. Trying to keep price in mind, would the Studio monitor 350's, 450's or PM500's be better? I'd only spend $500 if I had my way, but if a litle extra will yeild a lot of results, I'll be happy to spend a litle more. Since a pair of PM500's would cost around $800, maybe my real question is, is the Studio Monitor 450 a lot better than the 350? I've read the reviews of hte 350, but no one seems to have reviews of the 450's, anyone got a pair of those? Thoughts, opinions?
