The centre speaker BZ40C provides a significantly improved sound staging for both driver and co-driver offering the same excellent tonal balance as the other STEG UPGRADE speaker systems. The result: a perfectly homogeneous sound image, which clearly outperforms the OEM speaker setup in terms of resolution, precision and dynamics.

Especially in combination with one of our DSP amplifiers with centre management, this speaker reveals its full potential in respect of dynamics.
By the way, safety is a key point as well – needless to say that the BZ40C supports the SOS emergency call function of MB vehicles thanks to a separate voice coil.
