BOSE ® Surround Sound System.
The optional BOSE ® Surround
Sound System was specially
developed for the new 911 and
is therefore perfectly tuned to
the car’s specific interior acoustics.
A total of 13 loudspeakers (12 in
the Cabriolet and 911 Targa 4
models), including an active sub-
woofer and central speaker, and
a seven-channel digital amplifier
with a rated output of 385 watts,
combine to produce a truly memo-
rable sound experience.
During audio playback from audio
or video DVDs, the system is
now able to make full use of the
impressive sound spectrum of
5.1 digital recordings. With music
in the 5.1 format, the sound has
already been recorded in a multi-
channel format and is faithfully
reproduced exactly as the original.
Five dedicated audio channels (front
left, front right, centre, surround
left, surround right) deliver a sound
that is as authentic as it is natural.
The digital 5.1 surround sound is
balanced, lifelike and crystal clear.
A 360-degree sound experience
that is as close to a live perfor-
mance as you could imagine.
Of course, you can still play
traditional music sources such as
CDs, either in stereo or in one of
the surround modes generated by
the patented BOSE ® Centerpoint ®
system. The new algorithm of
Centerpoint ® II extracts an even
more precise and realistic sound
from the stereo signal.
The SurroundStage ® signal
processing circuitry developed by
BOSE ® assigns each individual
audio channel, whether sourced
from a DVD or generated by
Centerpoint ® , to a selected
combination of loudspeakers and
is therefore able to deliver an
optimally balanced surround sound
experience to all seat positions.
To complement these features,
the BOSE ® Surround Sound
System offers a comprehensive
selection of equaliser presets for
customised sound. The dynamic
loudness function increases bass
levels as you decrease the
volume, thereby compensating for
the decreasing sensitivity of the
human ear at these frequencies.
Moreover, the AudioPilot ® Noise
Compensation Technology uses
a microphone to continuously
measure the ambient noise inside
the vehicle and adapts music
playback automatically so that a
consistent sound is maintained
in all driving conditions.
In short, welcome to your very
own concert hall – one of the
fastest around.
