Are bipolar surrounds better than a simple bookshelf-type speaker for surroud duties? I have a 14'x15' room with 11.5' ceilings and hardwood floors. The seating is very close to the back wall. I was wondering if it would be better for me to use a set of bi-polar surrounds so that I could "reflect" some of the music off of the back wall. I was thinking of mounting the bi-polars on the side wall toward the back corner so that I could use the angle of the speakers to bounce the sound off the back wall and create a more enveloping effect. I hope this is in the right section. Thanks for everyone's help.
