Frequently Asked Questions about EM-MBF3


How does the EM-MBF3 Speaker Set differ technically?

The EM-MBF3 Speaker Set from Emphaser features a unique 2.1-way compo design specifically developed for the Mercedes-Benz Sprinter VS30. It supports full eCall compatibility and enhances sound staging with a center speaker. Technically noteworthy are the aluminum membrane woofers with Cambridge surrounds and neodymium magnets, which provide powerful sound. Additionally, they include a Faraday copper cap to stabilize the magnetic field. The 19 mm textile dome tweeters do not have ferrofluid cooling, which increases dynamics. A crossover with 12 dB/6 dB/octave at 5000 Hz improves sound separation.

What is the nominal power handling of the Emphaser EM-MBF3 Speaker Set?

The Emphaser EM-MBF3 Speaker Set has a nominal power handling of 50 watts RMS. This means that the speaker system is capable of continuously processing 50 watts of power without any sound distortion or damage. The ability to operate with a nominal impedance of 4 Ohm makes the system compatible with a variety of amplifiers that support this standard impedance. The RMS power ensures that the speaker set remains stable even with more demanding sound effects while providing clear and precise audio playback.

How is the crossover designed in the EM-MBF3 Speaker Set?

The crossover of the EM-MBF3 Speaker Set features a separation of 12 dB/6 dB per octave at 5000 Hz. This design allows for a clean separation between the tweeters and woofers, resulting in clearer sound reproduction. High-quality components in the crossover contribute to low signal loss and optimized sound quality. The crossover is also designed to optimally support the frequency range from 55 Hz to 22 kHz, leading to a balanced and detailed sound profile that is pleasant to the human ear.

What tweeter specifications does the EM-MBF3 set offer?

The tweeters included in the EM-MBF3 are equipped with 19 mm textile domes that forgo ferrofluid cooling to provide high dynamics. Textile domes are known for their lightness and stiffness, contributing to finer detail reproduction, especially in the higher frequencies. In addition to the material choice, the design of the tweeters ensures a natural and uncolored sound journey across the frequency spectrum. This construction supports the impedance of 4 Ohm, which is well matched to amplifiers optimized for this type of speaker.

What parameters influence the sound of the Emphaser EM-MBF3 speaker set?

The sound quality of the Emphaser EM-MBF3 speaker set is determined by several technical features. Firstly, it has a sensitivity of 88 dB, which defines the volume level that can be achieved at a certain input level. The aluminum diaphragm of the woofers and the Cambridge surround provide stable and even sound transmission. Furthermore, the frequency response range of 55 Hz to 22 kHz ensures that both low and high frequencies are reproduced accurately. Neodymium magnets enhance bass reproduction, while the crossover optimizes sound separation.

Is the EM-MBF3 set compatible with vehicles outside of the Mercedes-Benz Sprinter?

The main focus of the EM-MBF3 speaker set is on specific compatibility with the Mercedes-Benz Sprinter VS30, as this system features vehicle-specific connections. It is designed as a plug & play system, meaning it can be integrated into the intended vehicle model without major modifications. For use in other vehicles, custom adjustments would be necessary, particularly regarding the placement of the speakers and the electrical connections. Deviations in installation space, especially in other car brands and models, could complicate the installation.

How does the Faraday cage of the EM-MBF3 improve sound stability?

The Faraday copper cap included in the woofers of the EM-MBF3 speaker set from Emphaser plays a crucial role in enhancing sound stability. It ensures that the speaker's magnetic field remains constant and stable, which reduces distortion and increases sound fidelity. This results in clear and precise bass reproduction and improved overall dynamics. The use of this technique is a feature typically found in high-quality speakers and is essential for ensuring that even high volume levels can be reproduced without distortion.

What is the significance of the voice coil in the EM-MBF3 Speaker Set?

The voice coil in the EM-MBF3 Speaker Set, measuring 25 mm, is an essential component that controls the movement of the speaker diaphragm. It is connected to the diaphragm body and converts electrical signals from the amplifier into mechanical energy, which is then heard as sound. The size and precision of the voice coil significantly influence sound performance, particularly in terms of sound volume and clarity. A well-constructed voice coil ensures smooth movement, which in turn allows for distortion-free, precise audio playback across the entire frequency range.

How do the Cambridge surrounds affect the performance of the EM-MBF3 Set?

The Cambridge surrounds in the woofers of the EM-MBF3 Speaker Set significantly contribute to the physical control of diaphragm movement, enhancing tonal precision. By using Cambridge surrounds, smooth diaphragm movement is promoted without mechanical distortions. This supports the high dynamics and the system's ability to clearly reproduce both subtle and powerful audio passages. Additionally, they contribute to a longer lifespan of the speaker by reducing material fatigue from repeated use.

Is the installation of the EM-MBF3 Speaker Set in the Sprinter complicated?

The installation of the EM-MBF3 Speaker Set in the Mercedes-Benz Sprinter VS30 is designed to be straightforward, thanks to the vehicle-specific plug & play connections. These allow for direct integration into the existing system without extensive modifications required. The dimensions of the speakers are optimally matched to the intended installation locations in the vehicle, making the mounting easier. Special attention has been paid to ensure that the installation maintains E-Call compatibility and enables high-quality sound staging by strategically optimizing the placement of the center speaker.
