How do you share the sweet spot?

If a speaker "images" in different locations at the same time it most likely has no image at all.

Well I can assure you that is not true. Listen to a pair of Ohm, mbl German Physics or other good quality omni designs. The imaging and soundstage (when set up properly as always) is top notch. I have several pair of Ohms and have owned a pair for 30 years now and can vouch for that. I’ve heard mbl set up optimally as well and that is in a class of its own in regards to 3-d soundstage and imaging from most any location in the room.   You do need a very special room for that with those though.

Visiting Audiophiles get that spot otherwise it is me most of the time.

I have two chairs side by side.  When she complains, I slide it back over about 8" that puts me dead center.. Just don't tell her.. She's happy.

I can always tell when my chairs been moved. 1.  the floor is marked,
2. The Rolling Stones, and Rod Stewart LP are out.. Her chairs is in the middle. I found her RE-taping a spot,  gettin' all pissed because, her tape was pulled, she pulled it.. and didn't mark it.. 2 hours to get happy..
Good ears.  She learned 25 years ago. Smart Lady...You know for a GIRL, anyways.
Yea she's standing over my shoulder, yukin' it up right now...
Feb, was 45 years, been together.. Man that's a long time..
She agrees..LOL

When we concert in the backyard, 6-9 people, get a great spot

ONE WALL! Behind 4 speakers!  25 H X 60 W and 40 foot deep.
No back, No lid, No sides for 120 feet.
Pretty nice

I always order the guest (or guests) to sit in the sweet spot.  Hey, I'm always in the sweet spot.  I can easily live with my system's patently miserable off-center sound (I joke!)  so that guests might get a clue as to how wonderful the high-end experience is.
