I can confirm that the i4 Msport pro pack has the base 6 speaker system, the front speaker in the middle dashboard has no sound coming out of it and is only there for visual reasons to keep them all looking aesthetically the same. I must say the base system does lack sound overall and I am disappointed to say the least and regret not upgrading to the HK system. Several dealerships and BMW genius have all confirmed the base 6 speaker system which I will go with and also my own experience with it. I hope this helps and answers everyones questions. Side not I have owned the vehcile for nearly 2 months now also.
