Regular Dirac takes care of that. The current Dirac eliminates all my room modes and provides a much more articulate and multi note bass. I’d highly recommend doing some reading on how to setup Dirac as it’s a bit finicky. Would also recommend starting with the NAD curve or the newly suggested room curve in the later software."Bass performance suffers when the sound waves from speakers and subwoofers start to bounce around a room,"
That's exactly the issue I have with my current seetup, I wonder if the current DIRAC implementation in the M33 is good enough. I guess there's only one way to find out.
