Thanks to vehicle-specific connections, the system integrates seamlessly into the factory installation locations of these vehicles. The integration occurs without modification of the interior, as the set has suitable dimensions to fit into existing mounting locations. Because the vehicle-specific fit has been taken into account, it is an ideal choice for owners of BMW and Mini models who want to enhance the sound of their audio system without compromising the original design.

What technical highlights does the EM-BMWC1 speaker system offer?

The EM-BMWC1 from Emphaser is equipped with several technical highlights. It is a 4-inch 2-way coaxial system with a robust aluminum diaphragm and an aluminum die-cast basket that ensure a balanced sound. The 13 mm tweeters with textile dome provide clear highs. A durable Connex centering spider and rubber surround ensure high longevity. The switchable 150 Hz/6 dB high-pass filter allows for extended sound control options. With these features, precise and powerful audio playback is achieved, ideal for music lovers seeking detailed sound performance.

What is the nominal power handling of the EM-BMWC1?

The nominal power handling of the EM-BMWC1 from Emphaser is 25 watts RMS. This power capacity allows the speaker system to produce a clear and punchy sound that remains distortion-free at both low and high volumes. The carefully tuned frequency response of 150 Hz to 22 kHz ensures that both low and high frequencies are reproduced accurately, while the sensitivity of 90 dB makes the speaker particularly efficient, achieving powerful output even at lower amplifier power levels.

What special materials are used in the EM-BMWC1 speaker system?

The EM-BMWC1 from Emphaser uses a combination of high-quality materials to ensure optimal sound reproduction. This includes the aluminum diaphragm and the aluminum die-cast basket, known for their lightness and stability, resulting in minimal distortion at high power. The fabric dome of the 13 mm tweeter provides soft and clear high-frequency sounds. Furthermore, the Connex centering spider combined with the rubber surround offers top-notch durability and flexibility, ensuring that the speaker system maintains its sound quality and structural integrity even with intense use.

How is the EM-BMWC1 installed in the vehicle?

Installing the EM-BMWC1 from Emphaser requires you to place the speakers in the designated factory installation locations of your BMW or Mini vehicle. Thanks to the vehicle-specific connectors, the system is designed to be installed without additional modifications or special tools. The dimensions of the speaker allow for a precise fit, ensuring smooth integration. During installation, the switchable 150 Hz/6 dB high-pass filter can be activated to customize the sound. Simply following the included instructions will lead to optimal sound results.

What is the function of the switchable 150 Hz/6 dB high-pass filter?

The switchable 150 Hz/6 dB high-pass filter in the EM-BMWC1 allows for enhanced sound control. This filter helps remove unwanted low frequencies from the signal that the speaker cannot process efficiently. By activating it, the bass range is reduced, relieving the tweeter and achieving a clearer and more defined mid and high-frequency range. In practice, this means you can adjust the sound to your preferences, especially when listening to music with very low-frequency sequences. Using this filter can thus improve overall audio performance.

How is the sound quality of the EM-BMWC1 described?

The sound quality of the EM-BMWC1 from Emphaser is characterized by clear and precise audio reproduction, excelling in both the mid and high-frequency ranges. The aluminum diaphragm ensures a distortion-free sound image, while the aluminum die-cast basket supports the structural stability of the speaker. Thanks to the fabric dome tweeter, a soft high-frequency sound is produced. The 150 Hz/6 dB high-pass filter also allows for individual sound adjustment, making the system flexible to personal listening preferences. The combination of these features provides a balanced and dynamic listening experience in the vehicle.

What role does the Connex centering spider play in the EM-BMWC1?

The Connex centering spider of the EM-BMWC1 is a crucial component that ensures the precise alignment of the diaphragm movement. It stabilizes the diaphragm during sound reproduction and minimizes self-resonances, resulting in a smoother and clearer sound. This centering spider is made from durable material that maintains its functionality even with intensive use. In conjunction with the rubber surround, it provides a flexible yet stable suspension that is essential for correct diaphragm movement, significantly reducing any distortion at high volumes.

What advantages does the aluminum die-cast basket offer in the EM-BMWC1?

The aluminum die-cast basket of the EM-BMWC1 offers several key advantages. Due to its robust structure, it provides excellent stability for the speaker, which is particularly important at high volumes and during intense use. This stability prevents the speaker from deforming or developing unwanted vibrations that could negatively affect the sound. Additionally, the material is lightweight, reducing the overall weight of the speaker system, and is also resistant to corrosion. These properties contribute to the speaker's durability and ensure consistent sound quality throughout its lifespan.

How does the sensitivity of 90 dB affect the performance of the EM-BMWC1?

The sensitivity of 90 dB in the EM-BMWC1 means that the speaker is capable of producing a high sound pressure level with a given power input. This high sensitivity allows the speaker to achieve impressive volume and sound quality even with low amplifier power. In practice, this means that you will experience a noticeable improvement in sound reproduction even with the standard audio systems of your BMW or Mini, without the need for additional amplifiers. This contributes to efficient energy use and maximizes sound performance.
