I have a buch of audio friends and we get toghether weekly, we usually lounge around and share the sweetspot eventually, but when more than one wants the sweet spot putting a chair behind the sweetspot works very well, even 3 or 4 chairs lined up, one would be "near filed" and the last possibly a little too far, but still within range.
Now this is all male no touch implied, if it was my girlfriend I would probably get a sort of long lounge chair and have her sit on my lap! Now my wife dont care about soundstage, she still drops in some time and dance in front of one speaker very sessy! I love it, but I had to tell her to do it in the center so the sound stage is not damaged! ijijijiji
