Frequently Asked Questions about Mille Pro MP 28.3

What are the special features of the Mille Pro MP 28.3 Tweeter?

The Mille Pro MP 28.3 Tweeter from Hertz is particularly notable for its Tetolon diaphragm, which ensures excellent dynamics and angular dispersion. With a resonance frequency of 900 Hz and a high-frequency extension up to 28 kHz, it offers an expanded soundstage. The neodymium motor minimizes nonlinearities, allowing for precise audio reproduction. Additionally, an optimized FEA-simulated geometry provides the best performance in off-axis installations. The ferrofluid-cooled 28-mm CCAW voice coil ensures outstanding power handling. The combination of these features results in a unique and enhanced sound profile.

How is the installation of the Mille Pro MP 28.3 in the vehicle feasible?

The installation of the Mille Pro MP 28.3 is straightforward thanks to its sleek and compact design. The physical specifications show dimensions of 53.4 mm (A) and 28 mm (C), allowing for a variety of mounting options in the vehicle. Additionally, the wide range of installation accessories aids in OEM integration. A separate ultra-compact Crossover with level adjustment switch ensures easy customization. These features make integration possible without much effort, which is particularly advantageous in limited space conditions within the vehicle.

What materials are used in the Mille Pro MP 28.3 and what impact do they have?

The Mille Pro MP 28.3 features a Tetolon diaphragm that provides improved sound quality and excellent off-axis dispersion. The dual neodymium magnet ensures maximum field symmetry and increased transmission efficiency. The rear chamber is filled with natural fiber fleece, which provides better damping and 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.

What frequency ranges does the Mille Pro MP 28.3 Tweeter cover?

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 can cover 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.

How does the Tetolon membrane improve sound quality in the 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 provides increased lightness and stiffness, enabling more precise sound reproduction. Particularly designed for off-axis operation, the membrane offers uniform sound distribution in the vehicle space. These features lead to accurate reproduction of high-frequency sounds and significantly enhance stage imaging. For discerning music lovers, the Tetolon membrane is an essential feature for enjoying authentic and clear sound images.

How efficient is the drive of the Mille Pro MP 28.3 Tweeter?

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 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 under demanding audio modulations or high volumes.

What is the significance of the ferrofluid-cooled voice coil in the Mille Pro MP 28.3?

The ferrofluid-cooled voice coil used in the Mille Pro MP 28.3 improves thermal load capacity and reduces distortion under high power demands. One of the key 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.

What are the dimensions of the Mille Pro MP 28.3 and what significance do they have for installation?

The dimensions of the Mille Pro MP 28.3 are crucial for its flexibility in installation. Its compact size, particularly the outer diameter of 53.4 mm and a depth of 28 mm, allows 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 interference with the existing vehicle architecture. This makes it an ideal choice for users seeking a seamless sound upgrade option within their current setup.

What role does the separate Crossover play in the Mille Pro MP 28.3 system?

The separate Crossover in the Mille Pro MP 28.3 plays a critical role in signal processing and quality optimization of the system. It is designed to precisely separate high-frequency signals and direct them to the Tweeter. This circuit includes a level adjustment switch that can tailor 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 installation in already existing systems easier.

Why is the Mille Pro MP 28.3 ideal for off-axis operation?

The Mille Pro MP 28.3 is optimal for off-axis operation due to its innovative Tetolon membrane and 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.
