Sound System.
The road is perhaps the last place in the
worldin which you can still listen to music
without disturbance. Reason enough,
then, to upgrade your enjoyment the
Porsche way – together with the most
important manufacturer of premium
quality sound systems in Germany.
The result is a sound performance of
the highest level, specially matched to
your 911. The system has 12 amplifier
channels with a total output of 821 watts,
12 loudspeakers including an active
subwoofer with 300-watt class D
amplifier, a total diaphragm surface
area of more than 1,340cm
2
, and a
frequency response of 35 Hz to20 kHz.
The Burmester
®
system uses the
patented integral subwoofer, which
replaces the familiar separate subwoofer
and loudspeaker arrangement of other
systems. Analogue and digital filters
have been optimally defined for their
specific installation location. Ribbon
tweeters (air motion transformers, AMT)
have been used for unmistakably fine,
clear and undistorted high-frequency
sound reproduction with excellent level
stability.
All loudspeaker housings are perfectly
matched and deliver a natural and richly
textured spatial sound, even at top volume.
Music of the future?
Absolutely.
