What is Logic7?

Logic7 is BMW's optional professional HiFi stereo system which is an enormous upgrade to the standard stereo. Logic7 is a special digital audio signal processing mode for two-channel stereo signals and multi-channel multimedia signals. The objective of Logic7 is to create an experience in sound as true to the original as possible for all listeners within the car. The Logic7 system is comprised of four tweeters in the mirror triangles and in the parcel shelf, one 100 mm conical subwoofer serving as the central loudspeaker in the middle of the instrument cluster, four 100 mm conical subwoofers in the doors, two 100 mm conical subwooders in the parcel shelf, and two 210 mm central base loudspeakers beneath the front seats. A total of 13 speakers.

It's the best sound system I've ever had in a car!

I'm curious how it is compared to a Mark Levinson audiosystem in a Lexus. I heard that once and it sounded awesome. I was very impressed. My hope is that the logic7 in my new car will sound something like that!

100mm=about 4 inches. These are the mid-range speakers.

Perhaps this was already extensively discussed, and if so I'm sorry. I didn't get a good hit in search. Is it possible to add Logic 7 after delivery? The simple answer is probably no, but are there ways of swapping the stereo out?

I do not have Nav. I do have Sirius and it sounds awesome. :winkcool:
