Hello! I am currently setting up a 5.1 theater surround. I am looking at a Martin Logan Motion 8 center speaker (anyone have experience with this one?). The front right and left speakers will be in ceiling. I purchased a DT supercube 2000 sub. My room is 16'x14'. I am debating between the Speakercraft AIM7 two versus the AIM5 three for the front speakers...any suggestions? Thank you so much for your help!!
