Ditto. Assuming square-to-the-wall is intuitive to some users, and aimed right at you is to others, about halfway between these extremes is a good place to begin. This tweeter has good axial linearity and tends to be fairly forgiving, but toe is still a handy tone control....I toed them back out approximately 7° so that the tweeters are now firing about 6" outside my ears. It has helped a lot, and it also increased the already great soundstage width while still keeping a strong center image. I'll probably experiment with toeing them out a bit more.
