It delivers a significant improvement in sound quality compared to the factory-installed speakers and impresses with precise music reproduction, high power handling, and easy, vehicle-specific installation.

The 10-cm midrange drivers are equipped with glass-fiber cones that are both exceptionally lightweight and sturdy. The powerful dual-neodymium driver, featuring high-quality N42H magnets, delivers dynamic and detailed sound reproduction even at low amplifier power levels.

The 25-mm titanium tweeters with neodymium magnets included in the set ensure brilliant high-frequency reproduction. They offer high resolution, clear detail, and a linear frequency response extending beyond 20 kHz.

Thanks to the vehicle-specific plug-and-play connectors and the included mounting adapters, the speakers can be installed in numerous BMW models without requiring extensive modifications to the vehicle's original wiring.
