I am trying to build a HT system. All i have now is the moniter which is an RCA 53" wide screen. I plan on doing a 7.1 setup with , a pair of, rf-3's, rb-3's, rs-3's and an rc-3. I was debating which sub to use. Either the rsw-10 or the ksw-12. I was trying to keep everything in the reference series but the reference subs are soooo expensive. Any sugestions?
