I'm in the process of finishing my basement room for home theatre and I'm trying to decide where to run wires and wall mount my surround speakers.

I know that Dolby recommends having the surrounds beside the listening position and not behind. However, it seems that my best option is going to be to wall mount them in the rear corners of the room which are about 3-4 feet behind the couch. Wall mounting is preferable due to children and the positions beside the couch are awkward due to a door way and some wall sconces.

My question is whether or not this position for the surrounds will be a significant compromise in the surround sound effect.

Thanks in advance
