Frequently Asked Questions about Mille Pro MPS 300 S4 / S2

What performance features does the Hertz Mille Pro MPS 300 S4 / S2 Subwoofer have?

The Hertz Mille Pro MPS 300 S4 / S2 Subwoofer impresses with an RMS power handling of 500 watts and a peak power of 1000 watts. It has a frequency response of 25 to 400 Hz, allowing for exceptionally deep and versatile bass reproduction. The impedance is 4 ohms. The voice coil with a diameter of 38 mm offers high thermal stability and excellent efficiency. For audiophiles who appreciate powerful and clear bass, this subwoofer is an excellent choice, notable for its high performance and superior depth-to-power ratio, which ensures precise and dynamic sound quality.

How does the diaphragm excursion affect the performance of the Mille Pro MPS 300 S4 / S2?

The Hertz Mille Pro MPS 300 S4 / S2 Subwoofer features a diaphragm excursion capacity that is 20% higher than conventional designs. This increased Xmech of 20 mm allows for greater movement of the diaphragm, resulting in more powerful bass reproduction. With the increased excursion, deep frequencies can also be reproduced accurately without causing distortion. This is particularly important for music genres that rely on deep bass, providing dynamic and clean sound reproduction even at high volumes. The improved excursion control contributes to the long lifespan of the subwoofer.

What advantages does the exceptional depth-to-power ratio of the Mille Pro MPS 300 offer?

The superior depth-to-power ratio of the Hertz Mille Pro MPS 300 S4 / S2 results from the combination of advanced diaphragm technology and effective magnet design. The polypropylene diaphragm ensures low distortion at high bass reproduction, while the high-density ferrite magnet provides the necessary driving strength. This ratio allows for excellent reproduction of low frequencies while delivering powerful performance without sound loss. The combination of these features enables the subwoofer to deliver precise and voluminous bass at both low and high volumes. This is particularly evident in complex musical pieces.

Which Thiele Small parameters does the Mille Pro MPS 300 define?

The Thiele-Small parameters of the Hertz Mille Pro MPS 300 S4 / S2 include important electro-acoustic specifications. These include an Fs of 23 Hz, indicating the resonance frequency. The Vas is 62.13 liters, setting the enclosed volume for optimal performance. The Qts value of 0.42 indicates the overall quality and describes the suitability for various enclosure types. The BL value is 18.7 T*m and indicates the electromagnetic drive strength. These parameters are crucial for selecting the right enclosure to achieve maximum efficiency and bass precision. For enthusiasts, such details are essential.

Can the Hertz Mille Pro be operated in a sealed enclosure?

Yes, the Hertz Mille Pro MPS 300 S4 / S2 is optimized for operation in extremely compact, sealed enclosures. With a suggested volume of 22.7 liters (0.8 cu.ft.), this design offers a sealed response, allowing for precise bass reproduction between 20 and 40 Hz. The high energy efficiency of the Subwoofer ensures tight and controlled playback without audible distortion. The diaphragm reduces resonances, keeping the sound image clean. This type of enclosure is ideal for users who prefer powerful yet accurate bass without sacrificing compactness.

What enclosure dimensions are optimal for the Mille Pro MPS 300 in a reflex system?

For a reflex system, an enclosure volume of 36.8 liters (1.3 cu.ft.) is recommended to optimally utilize the Hertz Mille Pro MPS 300 S4 / S2. The specific dimensions are: width 713 mm, height 372 mm, and depth 130 mm. This enclosure configuration allows a focus on the frequency range between 40 Hz and 80 Hz for maximum sound pressure level. The reflex design uses the enclosure opening to create additional bass enhancement, ideal for those who prefer high volumes and powerful sound with sufficient space. Consider these dimensions to achieve the best possible results.

What is the compatibility of the Hertz Mille Pro MPS 300 with enclosure installations?

The Hertz Mille Pro MPS 300 S4 / S2 is specifically designed for space-saving installations. With a mounting depth of only 88 mm and a diameter of 318.3 mm, this Subwoofer also fits into compact enclosures. Ideal for pickups or vehicles with limited space, as it can be mounted under rear seats or in tight spaces. The compact structure allows for flexible installation options, while the powerful design still delivers impressive audio quality. Just pay attention to the specific dimensions of the intended installation location to ensure that the Subwoofer fits optimally and can unleash its full power.

How does the Hertz Mille Pro MPS 300 perform in sealed enclosures compared to reflex enclosures?

The Hertz Mille Pro MPS 300 S4 / S2 exhibits particularly precise and tight bass performance in sealed enclosures due to optimal damping, ideal for music that requires clear bass lines. In comparison, the reflex design allows for higher sound pressure levels with enhanced bass energy, suitable for bass-intensive music styles. The sealed enclosure offers a frequency response of 20 to 40 Hz, while the reflex design operates more powerfully in the range of 40 to 80 Hz. The choice of enclosure thus significantly influences the sound experience, depending on the preferred music style and available space. Consider enclosure specifications and installation requirements.

What specific materials and technologies are used in the Mille Pro MPS 300?

The Hertz Mille Pro MPS 300 S4 / S2 uses a polypropylene diaphragm for low distortion and high stiffness, ideal for powerful bass reproduction. The high-density flux ferrite magnet provides excellent magnetic properties, offering greater drive strength and control. Additionally, the Subwoofer features a 38 mm voice coil made of robust material for better heat dissipation and stability. These materials and technologies contribute to the outstanding bass intensity that is both precise and powerful. Audiophiles who value technical sophistication will appreciate the carefully tuned components.

What frequency range does the Hertz Mille Pro MPS 300 cover?

The Hertz Mille Pro MPS 300 S4 / S2 Subwoofer covers a frequency range of 25 to 400 Hz. This range allows for deep bass reproduction that excels in various music scenarios. With an Fs of 23 Hz, the Subwoofer is particularly good at producing the lowest bass frequencies, providing an impressive sound experience. The wide frequency range also offers flexibility for integration into different audio systems, whether in a car or at home, capturing both low frequencies and lower midrange frequencies, resulting in a particularly rich audio experience.
