Extensive underbody paneling helps smooth the flow of air that passes beneath the car, keeping the front end grounded at speed. A tapered front trunk lid enhances downforce even further, contributing to an impressively low drag coefficient of 0.29, while raked headlamps and wheel arches present a virtually seamless surface to the wind. For the ultimate audio experience, the Cayman and Cayman S can be equipped with an optional Porsche Bose Surround Sound System, developed jointly by Porsche and Bose engineers. The Bose approach to acoustic design is very similar to the design philosophy of a Porsche: Engineer each component to the highest standards of performance, then integrate them in such a way that the whole becomes greater than the sum of its parts. Thousands of measurements from every conceivable angle were used to determine the precise placement of each component for countering road, wind and engine noise. Ten perfectly placed speakers arepowered by a seven-channel digital amplifier and active equalization that matches sound to the unique acoustics of the Cayman interior. The Bose system uses independent channels to generate a push-button panorama of space and sound. The extraordinary sense of depth is increased further by patented Bose Signal Processing and a Centerpoint® technology that can split stereo recordings into five separate channels. A fiber optic network beneath the dashboard integrates 5 x 25-watt linear amps and a single 100-watt switching unit with sparkling signal quality, while a second switching amp in the active subwoofer offers an additional 100 watts of power. The system’s dynamic loudness technology actively compensates for the reduced sensitivity of the human ear at lower frequencies by enhancing low-volume sounds that go unnoticed with other systems. At speed, the Bose system helps ensure that you never miss a beat. AudioPilot® Noise Compensation Technology automatically adjusts tone and volume based on speed and ambient noise in the cockpit. The result is highly accurate and consistent sound with virtually no need for manual adjustments. Like the Porsche Cayman, it’s wired for the highest levels of performance.
