Many in the US felt shortchanged by this system so BMW changed back to the premium or Hi Fi system after/in september of 2010.
I believe its called the 2011.5 build

Just changing the speakers in that system will not help is it suffers from lack of power
a head unit eq curve that is set up to compensate for a lack of tweeters.
It requires a processor to flatten the output of the head unit , and amp and speakers to improve it.

The following board is the place to go for BMW stereo Mods to the E9x

Thanks for the info. Luckily I am not much an audiophile, most of the time I'd rather listen to my engine rev
