First timer here. So far i'm in love with my two R-28F's and R-12SW. I'm ready to add rear speakers and a center. I'm thinking about the RP-250C for the center and RS-42 II's for the rear. First question, how is my speaker choice and to they match up well? Second question with the RS-42 II's I would like to wall mount them and angle them down, how can I do that? Can I safely drill into the back without damaging anything internally or is there a better mounting solution for these?
