Ci3 C100.2FM-S3 CFMK-100 MB.1

Accurate, dynamic treble vividly brings your usual music to life.

【Ci3 C100.2FM-S3+CFMK-100 MB.1|10cm 2-Way Coaxial Speaker with Mount】

You may want a bit more clarity in the sound from your OEM speakers, or you may want vocal and instrument sounds to feel a little closer. If so, we recommend considering the MB QUART Ci3 C100.2FM-S3+CFMK-100 MB.1.

This 10cm 2-Way coaxial speaker reproduces audio from the center of the midrange up through the high frequencies using a single unit. The tweeter uses a 20mm titanium dome diaphragm and a neodymium magnet. It delivers accurate, dynamic reproduction of subtle details such as vocal contours and fine guitar and cymbal sounds.

For the midrange/woofer, it employs a cenospheres-coated paper cone and a 25mm voice coil. By replacing your OEM speakers with this model, you can more easily notice changes in the sound’s attack and the amount of information in the mid-to-high frequencies, allowing you to follow even the finer details in the music you already listen to.

With 10cm speakers, mounting conditions can vary significantly depending on the vehicle. Not only the speaker itself, but also the combination with the mounting bracket and its placement relative to the OEM location is important. This model includes the UniversalFlexMount100 adapter and the FlexConnect adapter (Type A), making it easier to consider mounting options tailored to your vehicle.

To get the most out of the speakers, it’s not just a matter of swapping them in—you should also confirm compatibility with the OEM system, the condition of the mounting surface, door-side treatments, and how the sound connects with other speakers. Because the best installation method can differ depending on the vehicle and the specifications of the OEM audio, I would, if it were me, confirm with the actual car and decide together with you using a practical, no-fuss configuration.
