Hertz Mille Pro MP 165.3 Datasheet

Frequently Asked Questions about Mille Pro MP 165.3


What sizes and installation depths does the Hertz Mille Pro MP 165.3 have?

The Hertz Mille Pro MP 165.3 is a 6.5-inch midrange speaker with a size of 165 mm. The physical installation depth is 74 mm, which is particularly advantageous for installation in vehicles with limited space. The parameters allow for adaptation to many vehicles with 165 mm speaker openings. Notably, the acoustically transparent basket made of aluminum alloy, elegantly finished with diamond cutting and the aluminum Hertz logo, enhances the product visually. This ensures seamless integration, even when space is restricted.

What is the power handling of the Hertz Mille Pro MP 165.3?

The Hertz Mille Pro MP 165.3 midrange speaker offers an RMS power handling of 90 watts and a peak power handling of 180 watts. This high performance results from the technically advanced design, such as the pure copper voice coil wound on a polyamide former. This leads to high power handling with minimal intermodulation distortion. The combination of these features ensures remarkable sound quality, even at high power. This is particularly relevant when the speaker is used in a vehicle without an additional Subwoofer.

Does the Hertz Mille Pro MP 165.3 offer special radiation characteristics?

Yes, through the use of V-cone® technology and the optimized exponential V-cone profile, the Hertz Mille Pro MP 165.3 ensures outstanding radiation in the mid-frequency range. This results in high linearity and ideal radiation characteristics, especially at mid frequencies. The Boundary Free Rubber Surround technology further optimizes radiation, particularly in the mid-bass frequencies, leading to a wider and more efficient sound reproduction. These features make it ideal for listeners who appreciate clear and precise sound reproduction across the entire frequency spectrum.

What frequency range does the Hertz Mille Pro MP 165.3 cover?

The Hertz Mille Pro MP 165.3 has a frequency response ranging from 40 Hz to 5 kHz. This allows for deep bass reproduction, even without support from a Subwoofer. The midrange driver is thus capable of covering a wide range of frequencies, which ensures a fully satisfying sound experience. In particular, the pressboard cone with cotton fibers contributes to the effective reproduction of this frequency range, as it positively influences the sound behavior at low frequencies.

What advantages does the high-density ferrite magnet in the Hertz Mille Pro MP 165.3 offer?

The high-density ferrite magnet used in the Hertz Mille Pro MP 165.3 provides significant advantages such as low distortion at high power levels. In combination with iron plates that have a very low carbon content, it ensures high precision and clarity of sound, even under demanding conditions. This design supports the output signal by reducing harmonic and non-harmonic distortions, resulting in a detailed and pure sound outcome. The magnet is a crucial factor for the sound quality of the speaker.

What electroacoustic specifications does the Hertz Mille Pro MP 165.3 have?

The Hertz Mille Pro MP 165.3 has several electroacoustic specifications that characterize its performance. The effective diaphragm diameter D is 132 mm, and the resonance frequency Re is 3.1 Ohms. The sound pressure sensitivity Scrap is particularly high at 93 dB, leading to impressive volume performance. With a mechanical quality factor Qms of 4.6 and a total quality factor Qts of 0.58, the speaker offers excellent vibration properties. These parameters are ideal for use in vehicles without additional acoustic reinforcement.

How is the installation of the Hertz Mille Pro MP 165.3 designed in terms of basket design?

The aluminum alloy basket of the Hertz Mille Pro MP 165.3 is acoustically transparent and has a low installation depth, making it easier to install in numerous vehicles. The elegant design with diamond cut and an aluminum Hertz logo emphasizes the high-quality workmanship. The positioning of the basket can be flexible, and its dimensions fit ideally into the 165 mm speaker openings. These construction features contribute to a successful integration, even in tight installation situations. However, the acoustic performance remains fully intact.

Which Thiele Small parameters are decisive in the Hertz Mille Pro MP 165.3?

The Thiele Small parameters of the Hertz Mille Pro MP 165.3 include, among others, the moving mass Mms of 14.9 g and the mechanical compliance Cms of 0.36 mm/N. These parameters significantly contribute to the sound characteristics and dynamics of the speaker. The electrical quality factor Qes of 0.67 and the resonance frequency Fs of 70 Hz are additional crucial values that facilitate adaptation and integration into various sound systems. These values are essential for achieving excellent resonance and finely tuned sound across different frequencies.

How does the press cellulose cone with cotton fibers affect the sound of the Hertz Mille Pro MP 165.3?

The press cellulose cone with cotton fibers in the Hertz Mille Pro MP 165.3 significantly contributes to sound quality. This material choice ensures a stiff and lightweight cone structure that minimizes resonances and enhances clarity, especially in the bass and midrange frequencies. The cone allows for smooth and precise sound reproduction, reducing distortion. This functionality ensures that even at high volumes, the sound remains uncolored, which is particularly important for discerning listeners.

Is the Hertz Mille Pro MP 165.3 compatible with common car brands and what influence does the V-cone® technology have?

The Hertz Mille Pro MP 165.3 is compatible with a variety of common car brands, thanks to its compact size and flexible installation options. The advanced V-cone® technology simultaneously optimizes sound in vehicles by ensuring high linearity and improved radial dispersion in the mid-frequency range. Vehicles that typically use a 6.5-inch speaker can particularly benefit from this technological advantage with the Mille Pro MP 165.3. The speaker remains effective even in challenging acoustic environments but does not provide information on specific vehicle models.
