I am aware of the mythology on enabled dolby setups. However, in my room that is 12 feet long and not dedicated width, with 9 ft ceilings, I have experienced some benefit. My height channels are Elac A4's. I have a modest energy 5.1 surround speakers with an Onkyo s710w amp. Room is running 5.1.2. My question is proper crossover for the elac height channels. Currently set at 80 with the rest of the speakers. My second qusetion is to determine the proper angle for these speakers. They are set at the proper no more than half way up the wall standard. However, given my room 12 ft length, should they be perhaps angled more to take advantage? What is a proper formula to determine the best angle? Any suggestions would be benifitical. Thanks.
