So - Im going back to 5.1 from a soundbar know the missis has been converted - BUT our room is not great - and because of other furniture that Im not allowed to move, I,m gonna have to wall mount all 4 "outside" speakers (FL, FR, RL, RR) and in the top corners of the room. This isnt a problem for the rears, but not ideal for the Front L and R. Will I get away with it, or will it compromise the sound too much? If I do this can I get wallmounts that will allow me to tilt the speakers down slightly? I could live with the soundbar for another 18 months till we move home and get then if its not a good idea. Thanks in advance.
