Revolutionary Tetolon membrane for clear highs and precise dispersion

The Hertz MP 28.3 tweeter impresses with its Tetolon cone, which was specially developed for maximum dispersion in off-axis operation. Tetolon combines the properties of silk and synthetic fibers to ensure exceptional fidelity and durability. FEA-optimized simulation enabled the cone to be designed to offer high dynamics and precise angular dispersion. A higher value than the existing one would further improve dispersion, but possibly at the expense of durability. The selected cone is perfectly balanced for its specific application as a tweeter.

Neodymium motor minimizes distortion for authentic sound

The dual neodymium motor of the Hertz MP 28.3 is a technological highlight. This drive technology has been optimized to achieve maximum field symmetry. This symmetry ensures exceptional transmission efficiency, minimizing distortion and keeping the sound authentic and vibrant. Compared to ferrite magnets, neodymium offers greater energy efficiency, allowing for a more compact design. A stronger magnet could result in even more powerful sound, albeit at the cost of increased size.

Tweeter with 900 Hz resonance frequency for distinctive acoustics

One of the outstanding features of the MP 28.3 is its low resonance frequency of 900 Hz. This ensures a well-damped high-pass roll-off, enabling optimal frequency transition. A resonance frequency at this level gives the tweeter the flexibility needed to perfectly harmonize both with midrange drivers and in complex car hi-fi setups. A lower value could allow the tweeter to be integrated into even more complex frequency ranges, but would limit control over peak loads.

Powerful BL product of 2 T*m for optimal drive balance

The force factor (BL) of 2 T*m for the Hertz MP 28.3 tweeter points the way to optimal drive balance. This value reflects the interaction between the coil and the magnetic field, thus ensuring efficient energy transfer. Increasing this value could lead to further efficiency improvements, but with the risk of electromagnetic overload, especially in relatively small vehicle installations. The given value is an excellent compromise for car hi-fi systems that require linear sound reproduction.

Precise SPL level of 91 dB for dynamic sound reproduction

With a sound pressure level (SPL) of 91 dB, the Hertz MP 28.3 tweeter delivers a powerful sonic presence, ideal for dynamic music genres. This SPL level ensures impressive volume with relatively low energy input, which is also advantageous in acoustically challenging vehicle environments. A higher SPL value would potentially enable even higher volumes, but could be prone to distortion if driven suboptimally. For its intended purpose, this value is perfectly balanced for a blend of efficiency and sonic expressiveness.

Low voice coil inductance of only 0.024 mH for precise high-frequency reproduction

One of the key features of the Hertz MP 28.3 is its voice coil inductance of just 0.024 mH. This low inductance enables fast and precise high-frequency reproduction, ideal for faithfully reproducing even complex musical passages. Lower inductance values ​​could theoretically allow for even more detailed high frequencies, but at the expense of overall power handling. The existing inductance value is thus optimally tuned for excellent high-frequency reproduction in a wide variety of car hi-fi setups.

Convenient installation thanks to FEM-optimized housing geometry

The Hertz Mille Pro MP 28.3 features a FEM-optimized front panel that optimizes the cabinet geometry, making it ideal for off-axis installations. These design measures ensure high linearity and facilitate perfect integration into existing car hi-fi systems. The geometry allows for flexible installation options that would otherwise be limited if the shape hadn't been optimally adapted. In conjunction with the included mounting accessories, installation is also particularly user-friendly.

Consisting of a resilient CCAW voice coil for excellent music performance

The massive, ferrofluid-cooled 28 mm CCAW (Copper Clad Aluminum Wire) voice coil in the MP 28.3 tweeter guarantees first-class power handling. This enables long, undistorted playback times at high power levels without power reduction or sonic distortion. An even larger voice coil would allow for increased power output, but could compromise the overall size. CCAW offers an ideal balance here, combining the advantages of aluminum's lightness with copper conductivity.

High-quality accessories for easy integration into your car hi-fi system

The Mille Pro MP 28.3 tweeter comes with a separate, ultra-compact crossover, providing installation flexibility. Along with level adjustment capabilities, you have customization options to precisely match the sound to your vehicle. The accessory allows for easy OEM integration without compromising sound quality. A larger crossover could offer more customization options, but potentially at the expense of installation complexity. The included configuration is also suitable for most vehicles and ensures straightforward installation. Ready to bring this first-class sound experience into your vehicle?
