Technically this is a form of dynamic EQ based on speed. That also explains why it sounds lackluster at low volume and semi-decent at high volumes. And that's the reason I just ripped this sucker out of my M3 for aftermarket.
Yes that is commonly known about these systems. Dexx is referring to the system having a dynamic EQ in reference to it almost self adjusting itself with some internal mic in the car.
The EPS system does not have a dynamic EQ based on what is being played. Only on speed, and with s-vol at the lowest setting, it's a non issue.
