Best bookshelf speaker placement?
I have a 15ft wall my tv is on and it travels 35ft back. Approximately 12ft from the tv is the main seating. I just purchased 2 Def Tech Sm45's. I am trying to figure out best speaker placement.
I am going 7.1. Currently, I have 4 Mirage Nanos setup, 2 are in the front corners and 2 are 5ft behind the main seating arrangement in the left and right corners. I'll be placing the nanos that are currently in the front LR positions to the middle and replacing their front positions with the SM45s. I am unsure where they would be best for proper sound placement. I have seen ear height and many other placements and as well away from walls but just purchased bookshelf wall mounts...
Any experience or professional opinions?
