I have the Monitor 30 bookshelf speakers and the R150 bookshelf speakers. Which set should I use as the Rear speakers and which set should I use for the Rear Back speakers for my 7.1 system? Not sure if it matters, but I have the monitor 50s for the front and the cs1 for the center channel along with a psw10 for the sub. Thanks for your imput and help guys.
