Help! Help! Help! Please someone. I keep being told conflicting advice on rear speaker placement. Some say as close to the ceiling as possible and pointing inwards towards my ears. Some say at ear level. Some say behind me at approx 5 feet above the floor. It's driving me mad I keep drilling holes in the walls. My system is DPL at present but I will be soon moving to DD. The speakers that I am trying to locate are the normal front firing (if that's the correct terminology)type and front ported. Sorry this is so long winded but I really need some INFORMED advice. Thank you to all in advance.
