OK, dip around 180Hz is bad subwoofer integration.
Obviously your dipoles don't use any dipole loss equalization (for bass) in xo and no highpass filtering for subs. How about subs, do they use plate amps with adjustable xo and phase? I promise, that perfect match is not even possible without dsp, but you can try your best.
As you had it, with no absorbent, it will give a lively, open sound, which you seem to like (as I do as well). Absorbent will change the sound.
My set up was a largish floor mounted ob. I used heavy absorbent against the wall, actual cushions. I had a real mish mash of cushions, dusters, wadding, and cannot remember how I ended up. I had to abandon the experiment because the baffle was completely inadequate, and vibrated like crazy.
One thing you might want to try, whether or not you use absorbent on the wall, is to use absorbent to the inner side of the baffle, to reduce the crosstalk between the speakers. This can even completely fill the gap between wall and baffle on the inner side, or not. I found it helped focus the sound. But you might prefer it without.

but the dip is also there, if the subs are off.. So this can't be right?
The subs have amps with controls.. i may have the volume a little bit too high but i like it that way
Mic position is important, but first null is typically below 100Hz (and mic is typically near half of room height). "00Hz could be front wall (behind the speaker) nulling , typical of dipoles. Rotating speakers and changing distance should make remarkable difference to it.
Illustration of OP's speakers without sub, and typical sub response with LR4 xo around 100Hz. This magnifies the obvious nulling around 200Hz.

Since op is using two subs, and they are placed close to the ob, my suggestion would be to experiment with the sub setting. Crossing it higher could fill the gap and sound more balanced.
Technically it would be normal 3way speakers.

I'll do more measuring this weekend. I already tested my speakers in a different room with drastically different placement but same results.
I managed to organize the same pair of speakers but with wings/sidewalls. I test them this weekend as well.
Just saw this thread. My non-pro suggestions for OP: try 1-foot from wall, and gradually increase "stuffing" to absorb >400hz. 0.3m*2 roundtrip-bounce will positive-reinforce 280hz (wavelength 1.2m) midpoint of dip, if the baffles leave open passages for 200-400hz bounce. (Notice in post #12 "green is the closest to wall" has the least dip.) If floor is suspect, use wool rug; if sub(s) are suspect, adjust their phase or "physically" LPF them to prevent cancellation.
