Surround Sound System.
The optional BOSE
®
Surround Sound
System was specially developed for the
911 models and is optimally tuned to the
specific interior acoustics of these cars.
It has a total output of 445 watts and
comprises 8 amplifier channels, 12 loud-
speakers and a patented integral 100-watt
active subwoofer. The combined effect
is a balanced acoustic pattern that
transforms your 911 into a fast-moving
concert hall.
Burmester
®
High-End Surround Sound
System.
When two iconic German manufacturers
join forces, the result is special. We’re
referring to Porsche and Berlin-based
Burmester
®
, one of the most respected
manufacturers of high-end audio equip-
ment worldwide. The optional Burmester
®
High-End Surround Sound System owes
its eminence to countless details, and one
goal: perfection in sound.
The system has 12 amplifier channels with
a total output of more than 821 watts,
Symphony number 911.
Now being performed in an open-air concert.
12 loudspeakers including an active sub-
woofer with 300-watt class D amplifier, a
total diaphragm surface area of more than
1,340 cm², and a frequency response of
35 Hz to 20 kHz.
Burmester
®
has introduced the patented
integral subwoofer, which replaces the
familiar separate subwoofer and loud-
speaker arrangement of other systems.
Crossover technology has been carried
over more or less unmodified from the
home audio sector. Analogue and digital
filters have been optimally defined for
their new installation location and finely
tuned following extensive in-car audio
testing.
The tweeters are ribbon-based air motion
transformers (AMT) and ensure unmis-
takably fine, clear and undistorted
high-frequency sound reproduction with
excellent level stability. All loudspeaker
housings are perfectly matched and
deliver superior bass foundation, defini-
tion and impulse accuracy. The result is
a natural and richly textured spatial
sound even at top volume.
