I have read all of the guides for placement of the rear surrounds in a 5.1 and have found a suitable location based on the shape of my room, but what I have not seen is what the vertical pitch of the speaker should be.
Since the rear surrounds are above the listening location should they be pitched down towards the listener, or should they be parallel to the floor so they are aiming above the listener? Also, does this change for a bipole/dipole setup?
Thanks
