Sorry to rain on a parade, but I have Aerius i's as well and the manual clearly states that the best side wall for these speakers is no side wall at all! This has been proven to me many times over. My RF has no side wall but the LF does. I have stopped a movie several times to investigate a noise at my back door (on the right 35 feet away) which was actually a sound effect from the sound track.
