I am debating getting a setup consisting of LSi-15s in the front, LSi-center, and I'm having trouble deciding between the LSi-7s or the bipole/dipole LSi-F/X set. See the attached pic (think backwards, pic is taken from the TV spot ): edit: Ok I was trying to post a pic here, but apparently I can't do that until I have 15 posts. Paste into your browser if interested: users.adelphia.net/~dpstrand/speaker_mounts.jpg As you can see, the best option I see at the moment is mount the rear right to the wall, and hanging the rear left from the catwalk. I'm a little concerned that the left will be near it's respective left wall, and the rear right will be right near a half wall; will that interfere with or screw up the sound from bipole/dipole speakers? Also the rear right will have a wall directly behind it where the rear left will not. I really haven't settled on the Polk's yet either... also debating the Axiom's. I've been trying to wait for my local Tweeter to get the polk's in so I can give them a proper audition, but I won't be able to hear the Axioms. Any suggestions here? I'm getting antsy!
