Today i went into my local HiFi store and was looking at studio 60's for my front end. Right now i have 20's there, but was gonna move them to the rear. So i told this to my salesman and he said that would be a mistake? He told me to go with the dipoles instead. Now i do 50% movies and 50% music. My system is as follows- Paradigm studio 20's in front, cc-470 center, servo 15 sub, KLH in the rear--- this is why i want to upgrade!! So if anyone could tell me why which one is better to go with, thanks in advance!! The Diepoles vs putting the 20's in the rear????? THX!!!
