About to upgrade my living room system but could do with some advice please on rear speaker placement. At the moment I have Monitor Audio BR1's and a BRLCR at the front and then Monitor Audio Radius 1's at the back. I will shortly be buying Kef Q series speakers to replace the front (Q750, Q650C and Q50A Atmos speakers) and would like to replace the Radius speakers with Kef T101's as I have read they are a good match for the Q series tonally and, if I get the white ones, will blend in nicely at the back of the room and be even less intrusive that the Radius cubes. The room is not an ideal shape though. At the moment, the perfect viewing seat is the right hand side of the sofa between the surround speakers in the picture below as that lines up with the centre of the TV and the front speakers...but it is not the centre of the rear speakers. I feel I could probably put the new rears in a better position but am not sure if they would sound ok mounted in up high to the sides, up on the ceiling against the back wall or lower down on the wall behind the main seating position. Would welcome any thoughts, suggestions, pros'/cons on this please.
