Porsche 928 | High-End Package

Porsche 928 – a polarizing vehicle

This customer car already had eleven previous owners, but you definitely can't tell by looking at it. Unfortunately, one of the previous owners tinkered a lot with the speakers, so that some corrections had to be made.

Since Porsche no longer has any spare parts for the speakers buy from Porsche, all the mounts had to be redesigned in the CAD system to provide a suitable fit for the new speakers.

In the doors 25mm neodymium tweeters which were complemented by extra flat 100mm midrange drivers. Since there were already matching but non-original grilles here, this is the only visual noticeable feature on the HiFi system.

The biggest challenge on the 928 is the 165mm rear woofer as the largest component of the 3-way system,as the cabinet is matched to the fairing contour. Here, too, we managed to fit a particularly flat woofer, so that the original condition remains absolutely unchanged.

The heart of this High-End System is a 5-channel DSP amplifier with 400W system power, which was individually adjusted to the vehicle and measured.

In this vehicle, a Subwoofer is also used in the area of the spare wheel, which produces a very pleasant and sonorous bass and thus rounds off the sound image. Of course, nothing of this can be seen, but it can be heard quite clearly.
