I have maundant short front central and rear (bipolar) speakers. I have a small living room whohc will double as hc room. trouble is I want to be seated as far from screen as possible. This means sofa against rear wall. Where do I mount the bipolar speakers. Will they be any good on the at high level (i.e. right above my head ant not really behind me (when seated) or will they work to the side of me (mpunted on side wall) not equedistant though?
