BMW M3 Convertible Audio System

A world-class audiophile sound system in a convertible is one very tall order indeed.

It is also exactly the sort of challenge that brings out the best in us.

We pulled out all the stops: going to Italy for exotic Hertz speakers featuring ribbon midranges that nestle right in the A-pillars, we buried a treasure-trove of exotic electronics in the bottom of the trunk, treated the doors to just the right amount of resonance-suppression, and while we were at it also snuck in some stealthy radar/laser protection. We’re really quite proud of this one.
