BZ40DII

Premium sound for premium cars...

The basic speaker setup in Mercedes vehicles does not meet the expectations of ambitious music lovers in many cases. For all those, the tailor-made STEG UPGRADE speaker systems offer the perfect alternative that opens new horizons of sound.
The 2-way coaxial system BZ40D provides much better precision and dynamics across the whole frequency combined with a fantastic treble resolution thanks to its 20 mm silk dome tweeter.
Especially in combination with one of our DSP amplifiers these speakers reveal their full potential in respect of dynamics.
