Hello audiophilites. I am having a house built and am planning a 5.1 or possibly 6.1 HT system. my concern is with the rear speaker placement. The room is about 15x15 and the couch will have to be against the rear wall. I will be using Klipsch RS-3 surrounds. I was planning on placing them about 7 ft from the floor on the back wall. I cannot place them on the sides in this room. will the sound be compromised too much . or will angling them down slightly make up for this. .The problem I have is that the house is sort of an open floor plan and the room where the HT system is going only has three walls. There is no wall to the right (when sitting on the couch) just behind, left and front. so I dont have much choice of placement. Has anyone had experience with mounting the RS-3's on the ceiling? pointing down? The idea of mounting the RS-3's vertical and angling in sounds like it may give me more sound dispersion down towards the listening position. another concern will be that the left surround will have a wall for the sound to bounce off of to the left of it, but there is no wall for the right speaker to bounce of of. Does anyone have this type of setup? and if so how does it sound?? This is my first venture into HT so maybe im being to picky, but i just want to make sure it sounds as good as it possibly can. Thanks for the advice.
