hey, I work at circuit city and get nice accomodations from polk. Even though i get a lot off, im still on a tight budget (all because cc pays crap nowadays with no commision) so i am getting the monitor 50s and have r15 as rears and a velodyne vrp12. On the accomodations, there were two centers, both for under 100 dollars. They are the csi3 and cs1. Now since the csi3 are made for the rti series, will it work fine with the monitor 50s (I really wanted the rti8s but were an extra 160. which is a lot for me.) ?
