Hi, I'm looking into setting a 5.1 setup for my 15' by 12' living room. I already have the main fronts and will probably purchase a Dayton 10 sub based on what I've read here so far. As for a center speaker and surrounds, I'm certainly impressed by Fluance's prices. I was wondering if you guys might have any other recommendations. Also, can Fluance bipole surrounds be placed freestanding on their bases, or do they have to be wall mounted for optimum sound? Thanks!
