Hey! So, I've been using 2.1 for a while now, and am finally planning to move up to 5.1. However, space in my room is VERY tight. The only place I'd be able to put surround speakers is BEHIND the couch, instead of beside it as most suggest. For this reason I am considering bipole speakers, as it seems I can place them behind my couch where there is room.
Here's my question, however. It's a rectangular room. The wall is 12 feet or so away from the back of the couch. This means the bipoles would be on stands. is it fine that there's no wall directly behind them for reverberation? the area to the immediate left of the couch is also slightly open
here's a really poor paint drawing. the rectangle is the couch, line towards the top is the TV, two small squares beside it are the current front speakers.
