The STEG BZ25 is a pair of high-frequency plug-and-play tweeters designed specifically for seamless integration into Mercedes-Benz C-Class W205, GLC X253, E-Class W213, and S-Class W222 models. These 25 mm speakers utilize a ceramic diaphragm and a neodymium magnet to deliver a clear frequency range from 1500 to 22,000 Hz with 25 W RMS power and a 4 Ohm impedance. To ensure a straightforward installation without modifying your vehicle's original wiring, the kit includes a dedicated crossover and a plug-and-play cable set. This setup allows owners of these specific Mercedes-Benz models to refine their car's audio clarity using components that fit precisely into the factory locations.
