I've installed a few 5.1's in same configuration your planing. If you go with the in ceiling option for the front left and right with the center in the wall under TV. I've had moderate success with this configuration. My experience is that it will come down to the acoustics in the area your planning this. A hollow room with hardwood floors and wood furniture might give you some problems with the sound coming from the ceiling down. A full room with carpeted floors and clothe seating would help. Try to install the speakers in such a way that the seating can be placed in the middle of the square. FL FR
Another option you may consider is surface mount cube style or low profile speakers. These can be placed in corners of room or directly above seating with the added advantage that you can point the speakers directly in the listening zone. Remember most in ceiling speakers are not directional (although some models have directional cones with limited movement) so good placement and spacing is important. It can be done! Hope this helps, I would be happy to assist anyway I can. love this stuff!
I am looking to put 5.1 surround in my house. I need some installation help. To begin I have a split level house where my main living area is upstairs. My ceilings are vaulted and probably 10-12 feet high. My main concern is my front speakers 3 speakers. If I did in wall speakers I would have spots for the left and center but not the Right because the wall ends and there is a door too close. My other option would be to put them into the ceiling but wonder if that is too far from the TV? (tv is mounted about 5 feet up) Also another issue is that if I do that there is a funky spot in my ceiling where the right side above the door is about 2 feet closer then the other area. This would lead my center speaker to be off a little as well. Would this really matter if I did the left and right in the ceiling up high and the center in the wall under the TV?
