*however* I just got the option and didn't look at it in detail, however what BMW claims is that it has a live DIRAC processor that supposedly sets up an EQ filter to make the audio "perfect" in real-time. I would imagine there is a microphone somewhere doing measurements. My current thought is the installation is f-d up and it's destroying the EQ curve instead of fixing it.

There's no microphone for real-time adjustment in this OEM system... the EQ curve is fixed from factory.
