I read someplace (in several places, actually) to place the sub in your listening position and then "crawl the room."
Good luck and enjoy!

1. I turned off the mains so all I was hearing was the sub. It occurred to me later this might be a bad idea as obviously all will be playing during listening.
Right. You want as many bass source locations as possible. They interact and add together. Locating subs based on how they sound alone, it will be different when the mains are on.
2. The bass is good here next to the listening position but it seems I can locate it due to the punchiness.Right. And also the frequency. And because there's only one. Subs work much better- go deeper, more articulate, smoother, harder to locate- the more you have. One thing you can try, point the sub at the wall. At bass frequency it makes no difference but the wall will reduce the amount of higher frequencies you hear, and that is what is localizing it.
3. As with speakers, my ear coming out 12”-24” from the wall tights everything up. Anyone running subs away from the walls? It’s a living room and there’s no WAF but it’s the living room so it has to make some sense.
Its always like this. Bass is always strongest by the wall, that's where the pressure wave stops and reflects back. If you want more bass sit by the wall, or put the speaker by the wall. Want less move em out. Want definition do like I do, speakers and seat way out, subs right by the wall. Mine are out about 2" firing into the wall.
Also, my plan was to replace junky sub with good sub. Integrate good sub and add 2nd sub down the road.
Good idea except don't replace, add. The more subs the better.
Think 5 is a lot of subs? Ha! Not even! https://systems.audiogon.com/systems/8690#&gid=1&pid=2
Thanks @millercarbon I’ll redo the crawl with the mains on. The mains go down to 48hz and are very punchy but I’ll mess with it more.
As for the junky sub, I donated to my daughter’s music sensory therapy classroom. They run a cheap AVR and little satellites but no sub. They were thrilled and I feel like the class is less helpful without the bass but like all schools here they operate on a penny budget so I was happy to donate.
I’m really hoping to avoid REW and all that as I will get OCD over it. I feel like I did a good job with the junk sub but this one being not-boomy-but-way-punchy makes it localizable. I’ll flip the sub so the driver aims at the wall. Hadn’t thought of that.
@millercarbon yes I run the interconnected from pre to power normally but reverse the speaker cables polarity.
I played around for about 30 minutes again and with swapping the interconnects to the sub (polarity) it seems tighter.
I will redo the crawl as you instructed. Something tells me this time I will get it closer to correct.
So my sub has been rolling and I’ve been happy. It’s on the back wall slightly behind the couch on the listener’s right.
As was the goal all along, I added a matching 2nd sub. Now in playing with placement. Currently, the new sub is on the front wall to the listener’s left. According to the crawl (done correctly) these 2 spots were the right spot. But is it?
i notice a lot of people run their 2 subs straddling the rack inside or outside the mains. Is this better even though the area to the right of the rack had less bass than it’s current back wall location in my room?
all the things I read says to run one on the front and one on the rear wall on opposite
sides of the width of the room to fill
the room better with bass. But maybe that’s home theater only?
