Update:
Tested subwoofers on both side of the wall, one 4th order bandpass through pipe, another sealed, close to the wall.
REW results at the main listening position. No DSP except 200hz crossover for sub on AVR, 1/6th smoothing.:
Pipewoofer in red. It has more output below 30hz and less above 30hz.
When listening on-axis, pipewoofer has some funny sounds going out, but when the listening position is around the corner, it's not a problem.
Also tested other possible locations (pipe is red):
Around 20hz it's still the strongest. Above that other locations pull ahead significantly.
Thinking of using other locations for 20-80hz range and to leave the pipe to deal with 20-30hz range, cutting everything above 30-40hz. Also could play with the pipe length, to see what happens.

Small update:
Still using two sub combo. Changed speaker and my main listening position, recalibrated subs from the start.
Decided to limit pipewoofer to ~40hz, main subwoofer goes to 100hz and LS50Meta play full range.
Subs after playing with phase, no EQ except 40hz low pass for pipewoofer and 100hz low pass for main sub:
After EQ:
Subjectively, pipewoofer helps a lot in lowest notes, can easily be heard when switching it on and off.
Will play with absorbers for a while, will return to subwoofer stuff later.
