I have a gift certificate at Best Buy burning a hole in my pocket. Here's the current either/or: a set of Athena B1's all the way around for 6.1, with a not so good sub I already have, or the Micra 6 with a better sub (and an extra speaker for the center rear I can pick up from Amazon). Both come out to about the same price. Can the B1's be wall mounted if I go that way, and will one make a good center? They're going into a medium living room and will be mostly used for movies. Thanks for any advice!
