Premium sound for premium cars...

The basic speaker setup in MERCEDES-BENZ 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 woofer component system BZ40B with car-specific baskets provides much better precision and dynamics across the whole frequency range combined with a fantastic treble resolution.
Especially in combination with one of our DSP amplifiers, these speakers reveal their full potential in respect of dynamics.
