The 911 | Comfort
BOSE
®
Surround Sound System.
The optional BOSE
®
Surround
Sound System was specially
developed for the 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
memorable sound experience.
During audio playback from audio
or video 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 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 authen-
tic 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 performance
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 algorithm of
Centerpoint
®
II extracts a 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 combi-
nation of loudspeakers and is
therefore able to deliver an opti-
mally 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 meas-
ure 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.
