Sweet Pic of me! 🤣
I have a one off recording of Amazing Grace recorded in a church downtown. Tom's rig put you in the church....it caught all of the ambient/ spacial cues of the church in a way I've not heard before.

Tom is the meticulous, measure to the nearest three places to the right of the decimal point kinda guy. <snip>
What I ended up doing after much discussion online, with nearby professionals and the like, was taking each main speaker and loosely moving them around (Spikes on) until I found the best lower spectrum reproductive efforts (no subs at this point). As soon as I found the best location, I took measurements and found the "best spot" to place each main.....at this point, I was not paying any attention to mid and upper frequencies and this was done by ear, using many different passages of certain low frequency albums.
As soon as the "spot" was found , I measured the front and rear sides of the speakers to within 1/6th of an inch from the side walls. Both speakers were in the same exact position away from the wall. Then I verified the rear two corners of each speaker the same way from the back wall, making sure everything was within 1/16th of an inch. I then made sure that the speakers were perfectly leveled. At that point, I tilted the speakers back to where the direction of the tweeter went to the outside of my ears about 2". I then measured from my chest bone, without moving, the exact measurement from L to R speaker to within 1/16th of an inch, pointing the laser directly above the tweeter.
I kept going back and measuring everything I just mentioned again and again, until all parameters mentioned were within 1/16th of an inch, verified by lasers and a laser tape measure. I have box-type speakers [Tyler Acoustics Lynbrook Sig. Series, 1 piece towers], so I could easily mount the laser(s) along the fronts, sides and anywhere else to take precise measurements. I would mark with tape on the walls where the laser(s) left the speaker and traveled across the room to behind the listening position. Basically, I measured just about every conceivable parameter I could imagine that would alter the distance of any driver to my ears.
That yielded to date, the best imaging and spatial locationality cues I had ever heard from my system....or any system I had heard, truth be told. Ever since then, about every two months, I will go through the same thing, just to make sure one of the speakers did not deviate from the original positions. It took me about a week to dial everything in to perfection. Don't think that this is a "quick" procedure. Just adjusting the tilt knocks off some of the other measurements, for example. I just kept chugging at it until it was done.
Then I added the subs and did the same things with them, then dialed them into the room, then into the mains. Have not messed with it ever since. When I finally went to "test" the system after listening to many albums, I used the newer Isotek ultimate setup disc to confirm what my ears were hearing. The rig passed with flying colors on all test and tune up tracks. The 360 degree test was outstanding and spot on.
From now on, I will just keep tweaking the gear, as the speaker location/setup for me is done and done for good. I feel that there is no need or room for further improvement on that aspect.
