How far do you sit from your speakers

FWIW I just finished reading Jim Smith's "Get Better Sound" and he recommends a slightly elongated triangle where the distance between the speakers (measured tweet to tweet) is 83% of the distance from your ear to either tweeter. Of course there are many variables here (speaker type, irregular shaped rooms, ETC) but I have found over the years that my setup typically fell pretty close to this arrangement without knowing about Jim's ratio. Based on my experience and what I've recently read, if your "traffic pattern" allows I would suggest you use all that length to move the speakers well out into the room and then sit closer to them and see what happens. This would also ameliorate the problem of having the entertainment center between the speakers.

Speakers are 8' to my toes, 9' to my ears. I wished I could sit further away but the room is the limiting factor.

My speakers are 6.5 ft from tweeter to tweeter. My ears are 8 ft from tweeters. This has worked well for me and I'm not sure I'd move the listening seat back even if the room allowed. When my system was in the living room I found myself moving in closer for critical listening.

9' from me, 10' from each other.
