If I'm guessing right you set the PEQs manually? Which is fine. But maybe if you have another few hours then maybe try out the auto EQ function in REW.So I received my Flex yesterday and started my sub integration attempts with REW and Umik-2.
It was an arduous journey. I crossed my KEF R3 and SVS 3000 Micro at 60Hz. Thank god for PEQ on the SVS sub. My room modals were like crazy. I actually had to remove the sub from a corner of the room and place it roughly 2 feet from the long room wall.
The toughest part was trying to EQ peaks and troughs between 60 and 300 Hz. Above 500 Hz the KEFs are extremely flat which is a good thing because Flex only has a 10 band PEQ.
It was a solid first attempt which took me like 3+ hours. And now I am getting used to a new and much flatter FR curve

It takes a bit of getting used to but it can achieve results very similar to Dirac in terms of flatness. And generally not even using all the bands! It is a remarkable tool.
I also have the Dirac option and can switch between the two. The only difference in sound which is obvious is the impulse response correction of Dirac. Impulse response sharpens dialogue, separates vocals in a choir etc. For some things I use it, some things better without.
