Technical information
Funktion im Detail
HiFi-System Professional LOGIC7 (E90/91, E60/61,
E63, E65, E70)
HiFi-System Professional LOGIC7 – 5 Channel
(E93, E64)
Further optimisation of the sound quality of the
midrange and treble loudspeakers with aluminium
membranes has lead to noticeably more
differentiated sound quality as compared to the HiFi
system. The harmonious spatial sound is generated
by the additional centre loud speaker and the new
LOGIC 7 equalising concept. Additional midrange
loudspeakers in the rear doors (in the E64 on the
rear sides) ensure excellent spatial sound in the rear
of the vehicle. The increased power output allows
for a higher maximum volume at a level of 110 dB
without distortion. The effect of driving noises is
automatically compensated by sensitive speeddependent
equalising in the bass range.
