Open datasheet

Frequently Asked Questions about Mille Pro MP 300 D2.3 / D4.3

What power range does the Mille Pro MP 300 D2.3 / D4.3 Subwoofer offer?

The Mille Pro MP 300 D2.3 / D4.3 Subwoofer from Hertz is equipped with an RMS power handling of 600 watts and a peak power handling of 1200 watts, making it ideal for intense music lovers. This high power is achieved through a four-layer CCAW voice coil with a diameter of 65 mm, wound on TIL-P material. The dual voice coil configuration of 4 Ω + 4 Ω allows for versatile integration of the subwoofer into various sound systems. Together with an exceptionally strong ferrite magnet, it produces powerful, voluminous bass that makes every car ride an auditory experience.

How does the design affect the sound quality of the Hertz Mille Pro MP 300 Subwoofer?

The design of the Hertz Mille Pro MP 300 affects sound quality through the exponential V-cone, which features an optimized geometry. This structure ensures maximum stiffness and deformation resistance of the cone even at high volumes. The mineral-infused paper diaphragm further enhances stiffness and damping, minimizing sound distortions. The IIR rubber surround also contributes to sound improvement by enabling higher SPL performance. The combination of these design features ensures that the subwoofer produces rich bass without sacrificing clarity and warmth.

What technical features distinguish the Hertz Mille Pro MP 300?

The Hertz Mille Pro MP 300 has a range of technical specifications: a voice coil diameter of 65 mm, an impedance of 2+2 and 4+4 ohms, and a high-density ferrite magnetic flux. The Xmech is ±27 mm, allowing for extremely high excursion, and a Qts value of 0.42 ensures a balanced frequency response. The electro-acoustic Re is 1.9 ohms, Fs is 24 Hz, and Le is 1.6 mH. An SPL of 86 dB guarantees efficient volume reproduction. These technical features define the Mille Pro MP 300 as a powerful subwoofer.

What enclosure volume is recommended for the Hertz Mille Pro MP 300 Subwoofer?

For the Hertz Mille Pro MP 300 Subwoofer, there are two alternative enclosure options: a sealed box and a reflex box. The sealed box requires a volume of 28 liters (0.99 cu.ft.) and is designed to deliver compact low frequencies with a Qtc of 0.82 and an Fb of 48 Hz. Alternatively, a reflex box with a volume of 36 liters (1.27 cu.ft.) can be used, which offers an Fb of 33 Hz to enable deeper bass reproduction. Both enclosure types benefit from precise panel cutting lists that frame the Subwoofer ideally.

Does the Mille Pro MP 300 Subwoofer fit in my vehicle?

The dimensions of the Hertz Mille Pro MP 300 Subwoofer are 321 mm in overall height and 187 mm in depth, with a recommended cutout size of 287 mm. This makes it compatible with most vehicles that provide enough space for a 12" Subwoofer. If your car has additional trunk depth, installation in both sealed and reflex enclosures could be quite straightforward. However, note that you need to create an enclosure that meets the minimum volume requirements and has a wood cutout to achieve the best sound performance.

How is the Hertz Mille Pro MP 300 Subwoofer best mounted?

Mounting the Hertz Mille Pro MP 300 Subwoofer requires you to utilize the included locking technology and the minimum dimensions of the Subwoofer for optimal placement in the enclosure. The six spokes of the aluminum alloy construction not only provide a stable structure but also feature built-in ventilation holes under the spider to efficiently dissipate heat. Be sure to use cables with a diameter of up to 8 AWG for the connections to minimize wiring resistance.

What materials enhance the performance of the Mille Pro MP 300?

The Hertz Mille Pro MP 300 Subwoofer impresses with high-quality materials: The excellently crafted aluminum alloy housing ensures low resonance, while the exponential V-cone provides robustness against mechanical deformations even in extreme situations. The surround is made from boundary-free IIR rubber, allowing for high sound pressure levels with stable cone alignment. Additionally, the water-repellent press paper membrane contributes to durability and front load capacity without compromising sound quality, while the high Qms factor favors some adjustment and refinement of the acoustic properties.

What connection options does the Hertz Mille Pro MP 300 offer?

The Hertz Mille Pro MP 300 Subwoofer is equipped with a flexible terminal block that accepts cables with a diameter of up to 8 AWG. This helps minimize wiring resistance in low-impedance configurations. A plastic cover prevents short circuits and provides additional protection for the connections. The connection options are versatile and allow you to integrate the Subwoofer into almost any Amplifier system, supported by the 4 Ω + 4 Ω DVC impedance configuration. This simplifies the connection and offers flexibility in installation.

What should be considered when choosing an Amplifier for the Mille Pro MP 300?

When selecting an Amplifier for the Hertz Mille Pro MP 300 Subwoofer, it is important to ensure that the power capacity of the Amplifier meets the RMS rating of 600 watts of the Subwoofer to achieve optimal performance. The impedance options of 2+2 and 4+4 ohms provide various connection configurations that can be adjusted depending on the choice of Amplifier. An Amplifier with a high output power that supports the peak capacity of 1200 watts is recommended to fully utilize the dynamic range of the Subwoofer.

Can the Hertz Mille Pro MP 300 handle extreme bass frequencies?

Yes, the Hertz Mille Pro MP 300 is specifically designed to handle extreme bass frequencies. With a resonance frequency (Fs) of 24 Hz and an Xmax of 17 mm, it delivers deep and powerful bass without distortion. The construction with a water-resistant pressed paper diaphragm supports the overall acoustic integrity. The massive ferrite magnet and precise diaphragm alignment ensure that even at maximum excursions, fidelity is maintained. Ventilation technologies and acoustically optimized materials also provide excellent sound reproduction even at high volumes.
