Hi lovinthehd, thanks for that. Your opinion on the 5.1.2, 5.2.2 and 5.4.2 means different speakers or positions of these? Also when you've said " I'd go with two pairs of overheads at a minimum(might install for 6/3pr)" what do you mean 6/3pr? and last, would I be able to get software that will help me with my particular room? and if this possible where could I aquire this software? Thank you so much for your input. Regards Clem
