Help picking speaker positions

[Defi]

Greetings everyone.

I spent a while today moving my speakers and subs around taking measurements. I used REW room simulator to pick a few good spots and then moved them around between those, and measured 10 spots in total. I have landed on the following 3 positions for the mains that I think turned out the best. Unfortunately I ran out of time to start moving the seating position around, but that would be my next task. Please let me know if there is any obvious choice from here. I kind of let my curiosity wander and position 1 (blue here) is in front of a door that I only need to access once in a blue moon, but it would mean moving the speaker (some tape on the floor to mark the position is probably sufficient). I just posted a picture up to 1kHz for quick reference (with var smoothing I think).

Ok why is it not letting me attach the .mdat. Please stand by. Edit: I can't figure out why it's greyed out when I try to attach it. txt in the meantime?

Some anecdotal notes for what it's worth: Pos1 is nearly up against the side walls and ends up being the closest to an equilateral triangle. The only problem I had with in in listening was that the phantom center was incredibly sensitive to being in the sweet spot, like the order of head-width, but when you're there it has quite a nice soundstage. The center doesn't disappear but it skews asymetrically in the direction you move (i.e. if I move my head a foot to the left the center seems to go 2 or 3 feet to the left). This placement is a lot of fun because there is so much room between the speakers you kind of forget they are there.

Pos3 is results in a narrower soundstage but a much broader sweet spot. I haven't spent much time actually listening at Pos2 yet.

Edit: Ok after the 1 millionth edit I've unstupified my caffeine riddled brain and attached something that I hope is useful. Please let me know if I can be more useful.

Ok I think I'm going to take a different approach... I'm going to find the best seating position by measuring the subs first, then from there mess around with the mains positions. I have the luxury of being able to move whatever I want down there, the room exists solely for listening. Front sub looks really good on the places I've tried, rear sub not so much and the only other place I could put that one is not the most convenient but I may have to try it if moving the couch around doesn't help. Planning to do some more measuring today.

I watched Pos1, it is quite good. Except for the bumps at 70-140 Hz.
What are your speakers and room layout?
There is more than one way to skin a cat\use subs..

Room is 14'8" wide, 25'6" long, and a dreadful 7' high.

I was coming here to give an update that kind of rules out Position 1 and basically negates my first post. So, I first found a couch position that works best with the front sub, as I was getting pretty good results with it. Then tried several positions for the rear sub. This was the best I could get. I don't know why these are kind of blurry but the red is the front sub and blue is rear.

Then I started trying different spots for the mains and measuring both subs and the speakers at the same time. So far this is my favourite positioning but I might try more. There is a 4dB gain on the mains, a high pass filter with a gentle slope at like 25Hz or something that was a very quick bandaid to the gigantic hump at 20-50Hz where the subs were overpowering and a 80-100Hz crossover... I can't remember. Everything else is untouched.

Then... up until now I had been using the 90deg mic orientation since I was dealing with the low end primarily and thought it wouldn't matter. Then I thought I'd try to see if the straight mic worked (and yes I switched cal) and things got weird orange is same measurement as above and blue is just the new mic orientation and cal...

So then I switched it back to 90 deg, and then it also was different from my initial 90deg measurement! There is no difference between these two aside from maybe the mic being an inch out of alignment.

I can see the mic calibration files taken during these measurements and they are correct... Unfortunately I ran out of time, but the last measurments I got were clearly suspicious. I will report back when I next have time to work on this... I also realized I have 2 Umik-1s because apparently I bought one 10 years ago when I was setting up my mixing station. Anyway, I'm sure I did something silly.
