Mine are about 5 feet from side walls, 3 feet from back of speaker to wall, speakers are angled in so I can just see the inner sides of speakers, It's been awhile since I measured how far they are apart but my sitting position is roughly the same distance as the speakers are apart. It is so system dependent if I'm using my Quads they sound best with just a slight bit of toe in, pretty much all my other speakers I use the current toe in where I can barley see the inner side of the speaker.
