I have klipsch rf-3II fronts and rc-3II center and my wife will not let me spend any more money (newborn christmas eve) I would like to DIY some rear surrounds that match the klipsh's. Any suggestions for drivers/xo'ers? I actually found drawings for the klipsh's speakers on their website under "classic", "reference", "rs-3" Is there someplace I can buy replacement klipsch woofers/tweeters and xo'ers? The website lists the part numbers. Or find out the spec's of them to find close alternatives? The box is the easy part.... Or should I just not worry about matching and just make some good speakers?
