I currently have Athena AS-B2s for my mains with the AS-C1 as my center. Surrounds are leftovers from an HTiB. I want to upgrade my speakers by replacing my mains and moving the AS-B2s to the back. BB currently sells the AS-F1s and AS-C1s for the same price. The AS-C1s can be oriented in the vertical alignment for use in any position. My question is this: which would you all prefer to have the AS-F1s for the mains or have AS-C1s across the front. My initial reaction is AS-C1s across because I'll be building a Tempest Sub near the end of the summer so low end won't be a problem. thanks in advance!!
