I did not realize they come with wall mounts so that does take care of one speaker the reasoning for ceiling mounting one is on one side of my room the wall pushes out about 4 ft. and has 2 huge windows in the bay area with a small cathedral ceiling in that bay, so wall mounting on that side is not an option, do to the windows so I am planning on wall mounting using the axiom mount that comes with the speakers for the wall side and then ceiling mounting the other using sirquacks method where the flat ceiling and cathedral meet sorry kinda hard to expalin,it actually looks like from your picture we have a similar situation. hopefully I will beable to acheive the same height using your method great info Thanks
