【UP S4MB-CTR｜10cm Center Speaker Compatible with OEM Replacement】

The UP S4MB-CTR is designed for those who want to replace the OEM center speaker to revisit and improve the clarity of speech and the cohesion of sound.

It features a lightweight, high-rigidity paper-cone diaphragm in a 10cm size, along with a magnetic circuit driven by a powerful neodymium magnet. The design provides a light, responsive sound onset and is also optimized to capture fine details in audio. It’s well suited for situations where you want to make sounds coming from the center of the cabin—such as vocals and navigation voice prompts—more natural.

A key feature of this speaker is its double voice-coil specification, which includes an audio-dedicated voice coil and an emergency-communication-dedicated voice coil. While enhancing audio sound quality, the configuration also takes the vehicle’s emergency communication function into consideration. This design helps prevent the warning light from coming on when replacing the center speaker.

Even though a center speaker is compact, it plays an important role in sound imaging and how vocals come through. It’s not simply a matter of swapping the speaker—proper installation requires considering the vehicle’s system and balancing it with the existing speakers.

At LOGON, we first confirm the vehicle model and the specifications of your OEM audio, then organize together the changes you can expect from the replacement and the installation work required. If you’re concerned about the sound of your center speaker or want to improve sound cohesion while making the most of your OEM system, please feel free to consult us.
