Speaker Placement - Frequent Placement Changes?

I used aI just today to configure my speaker setup. It had me move my speakers closer to the front wall. And my seating area 1 ft further away from the back wall . Much better. Far less boomy.

the parts all came from a 1958 Fisher President II Console I inherited from my Uncle Johnnie in 1973. 

That's pretty cool. I'm pretty sure you're one of the very few that can something like this about a speaker they own and use. 

Out of curiosity, for the two-off-center listeners, how far in front are crossing in front of the listeners? 2-3 feet?

Even millimetre adjustments have profound impact on soundstage localisation and bass response as well as overall transparency. 

I think that's where the education is for me, and something that I'm always really surprised about. Speaker placement can sometimes have a greater impact than a component change.

Add in the inevitable requirement for compromise in a shared living space, in this case the living room, and my options become more limited.

I'm jealous of members' who have dedicated (and sometimes detached) listening spaces. I'm fairly confident this isn't in the cards for me during this lifetime, but that's okay. Gotta have something to dream about.

I’ll need to take some measurements, but the chair(s) are further back than the speakers are wide apart.

this recording is incredibly lifelike

I recently listened at my friend’s house, his is nearly an equilateral triangle, less bass than my system, amazing realism, but his spikes prevent him altering his toe-in, so unless you sit dead center, one side drops out fairly quickly.

I listened the next day at my home, it was different, bigger but less intimate, better retained imaging off-center.

Next, I moved closer, sat at the spot at the dining room table where I clean LPs while listening, now an equilateral triangle, speaker toe-in unchanged. Now it became as intimate as my friend’s system. A similar ’slightly out’ toe-in.

This Panorama Photo gives you a better sense of arrangements in my setup, you can just see the front of the listening chair(s). It’s not as big as it appears, I’ll measure

Distances appear normal in this photo, toe-in adjusted for single center listener

A lot of people would never have a dining room table in the middle, and yet all imaging is Phantom, they are Mirror Imaged, my horn tweeters are high and inside; two way horn mid high and outside, the 15" woofer below. all tilted up, toe-in in, and L-Pads calibrated via test tones and spl mic, final by ear.

I measured my setup, room is 156" wide x 288" (13’-0" x 24’-0"long)

My speakers, center of front face, are

40" in front of rear wall; 27" from the side walls either side (102" between) 

single centered listener, distance center of speaker face to ears is diagonally 150" (180" from front wall) (108" open space behind to rear wall)

speakers toed-in aimed directly at center listener and tilted back so that Tweeter’s are aimed up at seated ear height, (see mid horn and woofer positions in photo above, they are a mirrored pair, tweeters inside L edge and inside R edge

Alternate Toe-In for Two Off-Centered Listeners

Chairs are each 24" off center, now diagonal to face of speaker is 145"

Aim Left Speaker to Right Listener; Aim Right Speaker to Left Listener

They cross 48" diagonally (44" horizontally) in front of the listener’s ears.
