I'm going to use KEF 9000 as fronts and center. I'm now wondering if i'm going to use the 2005.2 or 5005s as surrounds in 7.1 setup. I haven't heard either of them and was set for the 5005s. However I notice in the specs that he 5005s only go down to 100hz and the 2005.2s go down to 80hz. I'm have a SVS 20-39+ sub that is going to be used with the system and I would prefer to have the cut-off at 80hz or 90hz. Any comments?
