Is placing a sub next to and in line with a front R or L speaker OK? Yes, I'm somewhat new to 5.1 setups. Also sub is 15" wide and front spks are 19'' from side walls of a 15ft. wide room. So would placing the sub between the speaker and the wall be theoretically better or on the inside of the speaker between spk. and TV, 3.5ft. I use B&W 604S3 as mains and rears and music is 90% of listening. Most music does not need the sub but there are several CDs that do so the best music experience is what I'm looking for. Also due to a disability I can't be moving the sub a lot to experiment. Really appreciate any advise on inside or outside and distance from mains. Carson.
