subwoofer placement and measurements

[JD1]

After alot of reading I finally understood where my shortcomings were, you cannot compare a sweep vs a MMM measurement only a vector average sweep measurement is comparable to a MMM measurement which was what I was struggling with, second for EQ and room response a MMM is in my opinion the right way, as VA sweep takes longer although it's good to compare that result to the final MMM measurement or to begin with, I was trying to find optimal placement with sweeps when I should've done that with MMM and then on the best placement do a 16 Vector averaged 16 point sweep to certify said result.with that said, here is (1) 16 point VA sweep (no eq) + (2) MMM (no eq) + (3) MMM with EQ1 (3 bands) + (4) MMM with EQ2 (4 bands).

EDIT: (1) to (4) since I forgot to name measurements in rew

here are my REW preferences and RTA settings/appearance
I'm using a loopback cable (input 2 to output 2 and it goes via 2 rcas to wiim Ultra line in).

Just got KEF R5 Meta, and, I'm amazed, the speakers are heaven. Don't even feel like measuring

Yes, they are great.
When integrating one or more subwoofers.... Don't obsess with specific crossovers.... Focus more on the total response, with both mains+ all subwoofers playing together.
