Hi, currently trying to build up a 5.1 system using a processor (yam dsp-e800) in addition to my Sony TA-FB940R. Im looking to use all B&W speakers at the front, but my main problem is the rear speakers. Look... Do i go for bipolar rears on the side walls, or normal speakers? If i go for the bipolars rears, how close to the wall can i have them? Someone suggested using normal speakers pointed up at the ceiling from either side of the sofa...would this work? I could move my room around, but would rarther not. Cheers Stuart.
