Do line source designs tend to favor a particular amount of toe in or is that going to be purely dependent on room interaction, speaker to speaker to listening spot distance relationship, driver type and dispersion characteristics, etc? With my LS6's, I can't say I'm hearing any significant changes as I move from straight ahead/zero toe in to axis firing at my shoulders. Maybe the image focus tightens up a bit as toe in increases, but not to any noteworthy degree. I've only experimented a little, so I'm far from drawing any of my own conclusions...just curious what others have experienced.
