The optional BOSE® Surround Sound-System is compatible with both the CDR-30 audio system, which comes as standard, and the optionally available PCM. Developed specifically for Porsche, it has been optimised for the Cayman models. A total of 10 loudspeakers, including an active subwoofer 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 (only in conjunction with the optional PCM), the system is now able to make full use of the impressive sound spectrum of 5.1 digital recordings. With music in 5.1 digital 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. It’s a sound that's as true to a live performance or cinematic experience as you can get.

Of course, you can still play traditional music sources such as CDs (only format supported by CDR-30), either in stereo or in one of the surround modes generated by the patented BOSE® Centerpoint® system. The 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 both 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.

The BOSE® Surround Sound-System. A genuine – perhaps the only – alternative to the characteristic engine sound.
