The ferrofluid-cooled 28-mm CCAW voice coil provides excellent power handling. The combination of these features results in a unique and enhanced sound image.

Wie ist die Installation des Mille Pro MP 28.3 im Fahrzeug durchführbar?

The installation of the Mille Pro MP 28.3 is easy thanks to its elegant and compact design. The physical specifications show dimensions of 53.4 mm (A) and 28 mm (C), allowing for a variety of installation forms in the vehicle. Additionally, the wide range of installation accessories aids in OEM integration. For easy adjustment, the separate ultra-compact crossover with level adjustment switch is provided. These features make integration possible without much effort, which is particularly advantageous in confined spaces within the vehicle.

Welche Materialien werden im Mille Pro MP 28.3 verwendet und welchen Einfluss haben sie?

The Mille Pro MP 28.3 features a Tetolon membrane that ensures improved sound quality and excellent off-axis dispersion. The dual neodymium magnet guarantees maximum field symmetry and increased transmission efficiency. The rear chamber is filled with natural fiber fleece, which provides better damping and a more natural acoustic emission. This thoughtful material concept enhances sound reproduction, making the tweeter an excellent choice for high-quality audio playback in the vehicle. This material choice supports the durability and sound fidelity of the system.

Welche Frequenzbereiche deckt der Mille Pro MP 28.3 Hochtöner ab?

The Mille Pro MP 28.3 tweeter is designed for a frequency range of 1 kHz to 25 kHz. Its resonance frequency is only 900 Hz, which means it is capable of covering lower frequencies than conventional tweeters, ensuring a smooth transition between different speaker components. With its high-frequency extension up to 28 kHz, the highest frequencies can be reproduced with remarkable clarity and definition. This wide frequency coverage allows for a harmonious and complete sound image, ideal for audiophiles and music enthusiasts.

Inwiefern verbessert die Tetolon-Membran die Klangqualität im Mille Pro MP 28.3?

The Tetolon membrane in the Mille Pro MP 28.3 is optimized for outstanding dynamics and angular dispersion. Its material composition ensures increased lightness and stiffness, allowing for more precise sound reproduction. Specifically designed for off-axis operation, the membrane provides uniform sound distribution in the vehicle space. These characteristics lead to accurate reproduction of high-frequency tones and significantly improve stage imaging. For discerning music lovers, the Tetolon membrane is an essential feature for enjoying authentic and clear soundscapes.

Wie effizient ist der Antrieb des Mille Pro MP 28.3 Hochtöners?

The drive of the Mille Pro MP 28.3 tweeter is remarkably efficient due to the use of a dual neodymium magnet. This arrangement achieves a high field symmetry, which ensures excellent acoustic transmission. The ferrofluid-cooled 28 mm CCAW voice coil also supports high load capacity, keeping the speaker stable even under peak loads. The combination of these technically advanced features guarantees not only high operational reliability but also exceptional sound clarity and efficiency, even with demanding audio modulations or high volumes.

Welche Bedeutung hat die ferrofluidgekühlte Schwingspule im Mille Pro MP 28.3?

The ferrofluid-cooled voice coil used in the Mille Pro MP 28.3 improves thermal resilience and reduces distortion under high power demands. One of the essential functions of the ferrofluid is to efficiently dissipate heat, thus preventing overheating. This allows the 28 mm CCAW voice coil to remain stable under higher temperature loads, ensuring consistent performance even under demanding conditions. The advantage of this technology is evident in the system's ability to deliver clear and distortion-free sound over extended periods and at higher volumes.

Was sind die Abmessungen des Mille Pro MP 28.3 und welche Bedeutung haben sie für die Installation?

The dimensions of the Mille Pro MP 28.3 are crucial for its flexibility in installation. Its compact measurements, particularly the outer diameter of 53.4 mm and a depth of 28 mm, allow for easy integration into various vehicle models. Additionally, extensive installation accessories are available to facilitate customization. These dimensions not only support straightforward integration but also minimize interventions in the existing vehicle architecture. This makes it the ideal choice for users looking for a seamless sound upgrade option in their existing setup.

Welche Rolle spielt die separate Frequenzweiche im Mille Pro MP 28.3 System?

The separate crossover in the Mille Pro MP 28.3 plays a crucial role in signal processing and quality optimization of the system. It is designed to precisely separate high-frequency signals and forward them to the tweeter. This circuit includes a level adjustment switch that can adapt the sound to individual preferences by varying the volume by 0 or -2 dB. Thanks to its compact size, it can be flexibly integrated into the vehicle without taking up much space, making it easier to install in already existing systems.

Warum ist der Mille Pro MP 28.3 ideal für den Off-Axis-Betrieb?

The Mille Pro MP 28.3 is optimal for off-axis operation thanks to its innovative Tetolon membrane and the specially FEA-simulated front plate design. This construction ensures that even at non-focused listening positions, a uniform sound representation and improved angle dispersion occur. The extended rear chamber with sound-absorbing material also contributes to the clarity of off-axis representation by minimizing unwanted frequency resonances. This combination makes the tweeter particularly suitable for vehicles where the listening position is not centrally located in front of the speakers.
