Frequently Asked Questions about EM-MBC2


Why does the EM-MBC2 speaker fit perfectly in Mercedes-Benz vehicles?

The EM-MBC2 speaker is specifically designed for Mercedes-Benz vehicles of the 205 and 213 series. Its design fits precisely into the existing center speaker installation opening in the dashboard of these models. Additionally, the vehicle-specific plug & play connection terminals ensure that no changes to the original wiring are necessary. This keeps important vehicle functions, such as all vehicle warning signals and the e-call function, fully intact. These specific adjustments ensure seamless integration and optimal compatibility of the speaker in the required models, without compromising the original vehicle functions.

What materials are used in the EM-MBC2 speaker?

The EM-MBC2 speaker is equipped with a 4-inch aluminum diaphragm that offers high stiffness and low weight. This results in precise sound reproduction. The diaphragm is complemented by a rubber surround that provides the necessary flexibility and damping. A powerful neodymium magnet drives the system and ensures high sound strength and stability across the entire operating range. Additionally, the speaker features an aluminum voice coil carrier and a Connex centering spider, which together provide excellent linear motion control and durability.

How does the crossover of the EM-MBC2 affect sound quality?

The EM-MBC2 is equipped with an integrated crossover that uses a 6 dB high-pass filter at 150 Hz. This configuration allows for the suppression of unwanted low-frequency signals that could lead to distortion or undesirable sound. By specifically limiting the frequency reproduction to the range of 150 Hz to 20 kHz, the speaker can operate more efficiently, resulting in clearer and more precise audio quality. The crossover thus plays a crucial role in operating the speaker within its optimal working range and ensures impressive sound reproduction.

What technical specifications highlight the EM-MBC2 speaker?

The technical specifications of the EM-MBC2 speaker are impressive. The frequency response ranges from 150 Hz to 20 kHz, covering a wide spectrum of sounds. With a nominal impedance of 2 x 4 Ohm, the speaker offers flexibility in installation and enhances amplifier compatibility. The sensitivity is 84 dB at 1W/1m, indicating efficient sound radiation. Additionally, the speaker has a nominal power handling of 40 Watts RMS, allowing it to handle a variety of audio signals even at higher volumes. Overall, these features make the speaker a powerful audio component.

How is the installation of the EM-MBC2 in the vehicle?

The installation of the EM-MBC2 speaker in the vehicle is user-friendly and straightforward, especially for vehicles of the Mercedes-Benz series 205 and 213. Thanks to the vehicle-specific plug & play connection terminals, no additional adapters or modifications to the wiring are needed. The positioning takes place in the center speaker installation opening in the dashboard. It is important to consider the exact dimensions of the speaker to ensure it fits seamlessly into the designated opening, facilitating easy installation without any adjustments or technical know-how.

What role does the neodymium magnet play in the EM-MBC2 speaker?

The powerful neodymium magnet used in the EM-MBC2 plays a crucial role in the sound quality and efficiency of the speaker. Due to its high magnetic field strength compared to conventional magnet systems, it allows for stronger and more controlled excitation of the voice coil, resulting in better sound radiation and higher overall sensitivity. Additionally, the lighter weight of the neodymium magnet reduces the overall construction, positively impacting installation in space-constrained environments. This leads to a more dynamic performance without loss in detail reproduction, even at higher volumes.

What influence does the aluminum diaphragm have on the sound quality of the EM-MBC2?

The 4-inch aluminum diaphragm of the EM-MBC2 has a significant impact on the sound quality of the speaker. Aluminum offers an ideal combination of lightness and strength, ensuring excellent response times and minimal distortion. The use of a rubber surround supports diaphragm movement and provides controlled and flexible behavior even at high sound pressure. This interplay allows for detailed and precise audio reproduction across the entire frequency range, making the EM-MBC2 particularly interesting for discerning sound enthusiasts who prefer rich and clear sound.

What advantage does the sensitivity of 84 dB of the EM-MBC2 speaker offer?

The sensitivity of 84 dB at 1W/1m of the EM-MBC2 speaker means that it achieves a respectable volume even with low power input, which directly affects the efficiency of the speaker. This is particularly advantageous in scenarios where amplifier power is limited or where high output power is not desired to avoid distortion, for example. Additionally, music lovers benefit from the speaker's ability to deliver detailed tones with minimal energy expenditure, resulting in a clear and assertive sound profile.

What functions remain fully intact when installing the EM-MBC2?

When installing the EM-MBC2 speaker, all important vehicle functions remain intact. This includes particularly the general warning signals of the vehicle and the significant eCall function, which are essential for safety and the vehicle's internal emergency call system. The retention of these functions is made possible by using the directly available vehicle-specific plug & play connection terminals, which are compatible with the vehicle's original wiring. This compatibility makes the speaker particularly suitable for specific use in Mercedes-Benz models without any loss of functionality.

In which frequency range does the EM-MBC2 speaker operate?

The EM-MBC2 speaker is optimized for a frequency range of 150 Hz to 20 kHz. This range allows for clear and distinct reproduction of both low and high tones, ensuring a balanced sound representation. The use of a 6 dB high-pass filter at 150 Hz helps to filter out low-frequency noises, thereby improving the efficiency of the speaker. This frequency coverage is ideal for users who expect complete audio reproduction with excellent high and mid-range performance and who want to enjoy clear, natural sound during music or speech playback in their vehicles.
