Your room looks great Todd, nice job.
Equidistant isn't a set in stone rule regarding placement. Play with the speakers in several different width locations and see what you think, this can take up quite a lot of time so be patient. Find the placement that makes these speakers shine, so that whenever do find the sweet spot you can then go back and tweak 'em a little more after a couple of months 'cause you'll find that sooner or later you just can't seem to leave the things alone for any length of time without *another fine adjustment* ... happens to almost everybody.
