【For Replacing BMW OEM Speakers. Ci3 C100.2FM-S3+CFMK-100 BMW.2 10cm 2-Way Coaxial Speakers】

The sound from the factory speakers feels a bit lacking, and you’d like to hear vocals and instruments a little more clearly. If that sounds like you, consider Ci3 C100.2FM-S3+CFMK-100 BMW.2.

These are 10cm 2-way coaxial speakers. For the tweeter, they use a 20mm titanium dome diaphragm and a powerful neodymium magnet. The unit is designed for playback with strong high-frequency onset, making it easier to perceive the sound’s contours.

For the midrange/woofer, they use a cenospheres-coated paper cone and a 25mm-diameter voice coil. They’re well-suited for anyone who wants to enjoy vocal expression and the fine details of instruments with an impression that’s one step beyond the OEM speakers. Even when listening to your usual music on the commute, the setup makes it easier to notice differences in sound cohesion and information content.

Compatible with FlexMount100 and FlexConnect, the package includes mounting-related parts for BMW. However, even with the same BMW model, mounting conditions may vary depending on the model year and the specifications of the factory audio, so it’s necessary to confirm how it will be combined with your actual vehicle.

Speakers aren’t determined by a unit swap alone. The final result depends on the mounting base and mounting condition, compatibility with the OEM system, and how they connect with surrounding speakers. If it were me, I would first confirm the vehicle specifications and your current sound, and then organize whether to proceed with a speaker replacement only or to also consider mounting methods and adjustments.

If you want to enjoy BMW’s factory sound quality more naturally and comfortably, please contact us with your vehicle model, year, and current audio specifications. Rather than deciding the product by force, we’ll think together about a way that’s less likely to lead to regrets—tailored to your actual car.
