Surround Sound system.
The optional Bose
®
Surro und
Sound system was specially
developed for the 911 and is,
therefore, perfectly tuned to the
car’s specific interior acoustics.
A total of 13 loudspeak ers
(12 in the Cabriolet and
911 Targa 4 models), in cluding
an active subwoofer and
central speaker, and a seve n-
channel digital amplifier with
a rated output of 385 watts,
com bin e to produce a trul y
memorable sound experience.
During audio playback from au dio
or vide o DVDs, the system is able
to make full use of the impressive
sound spectrum of 5.1 digital
recordings. With music in the 5.1
format, the so und has already
been recorded in a multichannel
format and is faithfully re produced
ex actly as the origi nal.
Five dedicated audio ch annels
(front left, front right, center,
surround left, surround right)
deliver a sound that is as authentic
as it is natural. The dig ital
5.1 surround s ound is balanced,
lifelike a nd crystal clear. A 360-
degree sound experience tha t
is as close to a live performance
as you could imagine.
Of course, yo u can still play
traditional music sources such
as CDs, either in stereo or in
one of the surround modes

system.
The algorithm of
Centerpoint

extracts a prec ise and realistic
sound fr om the stereo signal.
The Surr oundStage
®
signa l
processing circuitry developed
by Bose
®
assigns each individual
audio channel, whether sourced
from a DVD or generated by
Centerpoint
®
, to a selected
com binati on of loudspeake rs
and is, therefore, able to
deliver an o ptimally balan ced
surround-sound experience
to all seat positions.
To complement th ese features,
the Bose
®
Surro und Sound
system offers a comprehensive
selection of equalizer presets for
cu stomized sound. The dynamic
loudness function increases
bass
leve ls as you decrease the
volume, thereby compensating
for the decreasing sensitivity
of the human ear at these
frequencies. Moreover, the
AudioPilot
®
Noi se Compensation
Technology uses a microphone
to continuously meas ure
the ambient noise inside the
vehicle a nd 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.
