The speaker systems in the F30 and F32 models are available in 3 different specification levels:

Base/ Basic Audio

This is the lowest-level BMW sound system, unavailable in the US and Canada. It consists of 6 speakers (4x Midrange, 2x Underseat Subwoofers) which are powered by the iDrive head unit with no additional BMW amplifier.

HiFi Sound Systems

This is an option one level above the Base system. This consists of 9 speakers and a seven-channel amplifier integrated into the loudspeaker system. The amplifier has no MOST bus connection and instead receives the switch-on signal via a separate line. Seperate speakers are installed in the HiFi system for the treble and mid-tone ranges. The HiFi system also has a mid-range speaker positioned as a centre speaker.

Top HiFi (Harman Kardon) and 'MOST' Sound Systems

This is the top tier BMW sound system. It consists of 16 speakers in total, with a 9-channel amplifier incorporated into the Sound system. The AMP is a bus connection in Media Orientated System Transport (MOST)

Speaker panels labelled with the 'Harman Kardon' lettering, a tale-tale sign of a Top HiFi (MOST) system
