I'm unable to localize the rear sounds since I'm using 2 dipoles for rears, still deciding whether to change them to monopoles.
They are place 7 feet above and behind, 4 feet apart, they are tilted downwards. I've inverted the dipole speakers so that the tweeters are lower. The speaker labelled left is on the left and the right on the right. Did not swap the speakers since it is suggested that if you invert dipoles you should swap the left and right, and when using dipoles for rear they should also be swapped so that cancels the swapping.
