I would put them within two feet of each corner, angled inwards from 30° to 45°. If the room is nearly square, then toe-in 45°. If very long and deep, then toe-in angle should be less.This placement will give you a nice, large "sweet spot". Best imaging is anywhere that is equidistant between speakers within 40° from the axis of each one. At high frequencies, there is about +/- 20° vertical pattern, so the speakers will sound great seated even at fairly close range. Best sound while standing needs to be done from a few feet back.
