Can you post your subwoofer "before" measurement?

Sure, in a couple of days though

I'm not asking for a new measurement, just a screenshot of the one you already did...

OK so your low levels on the L/R measurements are due to the sub. I'm not sure I've seen a measurement quite like that...

Anyway, so I guess first I wonder what problem exactly we are trying to solve here. Dirac will do what it can to "fix" the issue with the >50Hz hole in the sub response, but the question is whether your system has the headroom for it. How does it sound?

If it were me, I would try moving the sub to a few different locations see if I could get a better raw response. Small distances can even make a difference, these measurements are 20cm apart:



(From www.hifizine.com/2014/05/minidsp-nanoavr-case-study/)

Then see how the integration between L/R/C and sub looks. Getting the sub and speakers "about right" in level is helpful because if they are too far off the effective crossover frequency will shift.

HTH :)

If you had only 2 places for one sub (WAF and no other option in the house) as showned in this image, which one seems the less bad?

The blue line is the same response that Dirac (sub aside the right front speaker . The red line is for the sub aside the front left.

Well... that's sort of a trick question isn't it. Try both and pick whichever one gives the best overall result to you.
