2. yes it would work as center if you can accommodate it space wise. Polk csi3 or csi5 is the matching center channel
Thanks for the response. Would the RTI 8 make a better (more powerful, better sounding) center speaker than the CSI3 or 5? I read somewhere on here that the CSI3 is a bit underwhelming when paired with the RTI 8s, is that true?
