Bass management

I have my room working well with broadband absorption and diffusors however Im still not entirely happy with the bass
I use a minidsp for crossover and correction. I have tried flattening out the low Q peaks in the bass to pretty good effect though I feel it could be better

My room is a difficult 6m x 6m x 3m

I'm running distributed multiple subs with a 3 way above

After the long winded intro, I'd like to know if a software based bass management solution will work better than my current "measure and correct" strategy?

I was thinking of buying Dirac software or something cheaper that would still work well...

Thanks
