I have the Q7 and i'm using dirac to about 3k, whereas the other speakers i've used dirac on (kef r3, elac dbr62, revel m16 & m106), I only went as far as the lower mids. This shows up in the in room measurements in dirac as well (13 measurements). I also assume this is reflections. You have to be careful to not cut too much, or this will leave a hole in the midrange in the on/off axis measurements. Luckily there is a steep roll off after the presence reason, so as long as you drop the response evenly before then, there shouldn't be an issue.
What is interesting is that in Erin's measurements of the Q11 Meta, it showed a huge spike in the midrange of "ceiling bounce". I live in the UK, and have a 230cm ceiling, and it's a lounge so no way to absorb it unfortunately. That may be a reason for the need to feel that I have to "control" the sound. High volumes are a lot more intrusive than say, the Revel M106, which I could really crank it up.
