Manually time-aligning subwoofer(s) to mains - how to

Hello
Sorry for getting back to you so late.
I had a quick look at your measurement.
What I noticed first of all.
In contrast to your subwoofer, your front is extremely quiet.
You can adjust this in REW. But I would ask you to take two more measurements.
The front should achieve enough room gain when measuring.
I would like to see your front completely to be able to determine where the peaks and dips are.

Proceed as follows.

Time Ref on
Normal measurement at normal speed.
Front left 20-20000
Front right 20-20000 (to see if the alignment is correct)
Front left and right together
Sub 20-20000

Further questions.
What do you use to control the subwoofer?
Mini DSP, AVR?
How far away is the subwoofer from the REF loudspeaker in cm?
Are the front speakers already equipped with eq's?
Is the sub already with eq's?
Is the front aligned correctly (same distance to the microphone?)

Supplement
I would like to see the subwoofer complete so that the time length is the same. I look at measurements a little differently like this explanation in this example. That way I can rule out some things.
The frequency band of the subwoofer doesn't look good either. Have you tried different positions?

best regards Alex

What do you use to control the subwoofer?
Equalizer Apo copy L+R channel to another output so i can control it better with filters own eq etc.

How far away is the subwoofer from the REF loudspeaker in cm?
about 200-210cm

Are the front speakers already equipped with eq's?
not yet

Is the sub already with eq's?
not yet

Is the front aligned correctly (same distance to the microphone?)
yes
