Need advice on speaker placement for my new home theater setup. I have just order RTIa5's for the fronts and the CSIa6 for the center. For the interim i will be using my Onkyo sub. I also ordered 2 TC620i ceiling speakers to complete the 5.1 setup. I will be placing the LR fronts and the center in the proper position(s) for 5.1 setup. My question is where my ceiling speakers should be installed. I have 10' ceilings...and about 5' behind the listening area the ceiling starts dropping off at about a 30 degree angle into the next room. Should i place the ceiling speakers just above slightly behind my sitting position or mounted on the 30 degree angle which would be approx 5-8' away from the OP. My first thoughts was to install the 30 degree angle ceiling..spread apart extending just above the OP. What is confusing me is the "recommended" 5.1 setup is to the right or right above the OP. Really do not want to start making holes in the ceiling until i talk to the experts.
Also on the side note...will the TC620i be sufficient to suffice in my HT setup for mostly movies? I can send them back if needed...just trying to please the wife by taking down my bulky Onkyo's off the walls.
Any advice will be greatly appreciated...i am kind of second guessing my placement/ceiling speaker purchase.
