Is my room weird?

[stunta]

Below are Dirac measurements of one of my mains and of my subs. The mains FR seems so erratic that it has me confused - is something seriously wrong going on that I should be worried about? Dirac corrects it nicely, but I am curious if this kind of response is a sign of some underlying issue. My mains are JBL 708P.

Another question I have is crossover setting - Dirac (I use Dirac Live Bass Control with my Monoprice HTP-1 processor) automatically selects 70Hz as the crossover. I have two Rythmiks FM8 subs plus a REL sub (FR show below is of the 10" REL Sub). I got the FM8s to use as mid-bass modules to relieve the 708Ps from mid-bass frequencies in the hopes of getting better dynamics. If I set the FM8s in the mid-bass mode, DLBC doesn't account for it and treats all 3 subs as one, thus defeating my intent. Should I trust Dirac and assume that the 708P are good enough to handle down to 70Hz?

Thanks

it is totaly normal. most people will instagram-ify their meassurements.
even a perfect room becomes a mess once you put stuff into it

I don't see anything out of the ordinary. Without smoothing, things can look horrible at first. Can't really comment properly about Dirac and multsub & mid bass driver integration as my experience is nada with such implementations.
