Okay so currently my system is a 5.1 with KG-4's as mains, kg 2.5v as a center, and KG 1.5's as rears. My plan is to go 7.1 at some point and possibly use dipoles just don't want to spend the money right now. However I have my Quintet center channel from my last system and was wondering if it would be worth it at all to set it as a rear center?
