John, welcome. As you may have observed, the most common suggestion is that the main speakers be separated by about as much as the sitting distance. If you can't narrow your separation to less than 14', you should nevertheless be able to get a reasonably good soundstage, and it would be because of the relatively sharp toe-in to point the tweeters at your ears, not despite it. The use of a center channel speaker would help fill the middle on movies and using DPLII on 2-channel material would have a similar effect. The VP150/VP100 question has been discussed here fairly frequently, but I've heard neither and am uncertain as to whether the 150 has significantly better dispersion characteristics. As I've frequently noted, I prefer a vertical center speaker, which generally would be the M2 in the Axiom lineup.
