There's no way I can measure the distance exactly, but my head is a couple inches past 7' from the speakers. I did my share of experimenting/auditioning, too, before I settled on that distance. And this five+ decade audiophile continues to be a happy guy on the hifi front.
How far away from your speakers are you?
I thought it would be interesting to know how people position their speakers... do you have the freedom to put them where you want or do practicalities dictate?.. How far away are they from the listening position?.. How big's the room and how far away are they from boundary walls? My main speakers (Seas A26) are 1' from back wall, 3' from sides in a 14' by 20' room and my listening position is about 16' from the speakers. Just wondering how much floor space we're willing to give up to get the optimum placement.
