Frequent questions about Mille Pro MP 70.3

Was sind die technischen Hauptmerkmale des Mille Pro MP 70.3 Lautsprechers?

The Mille Pro MP 70.3 from Hertz is a 3" midrange driver equipped with a dual neodymium magnet structure. This allows for superior dynamics. It features a 20 mm CCAW dual-layer voice coil on a polyamide carrier, ensuring high load capacity. The V-cone® profile provides improved lateral radiation behavior, while the Boundary Free Surround offers an extended bass midrange frequency. Its exponential V-membrane made of pressed cellulose combines stiffness and lightweight construction, ensuring a wide frequency response and highest linearity.

Wie sieht der Frequenzgang des Hertz Mille Pro MP 70.3 aus?

The frequency response of the Mille Pro MP 70.3 ranges from 180 Hz to 18 kHz. This wide spectrum allows it to reproduce midtones and high frequencies accurately. The exponential V-membrane profile is particularly responsible for this linearity in the frequency response, while the V-cone® profile optimizes the radiation behavior. The rubber surround with 'Boundary Free' technology also supports efficiency across these frequency ranges. This combination of technologies ensures that the speaker reproduces every nuance of the music accurately.

Was ist die Bedeutung der V-Membran-Profil® im Mille Pro MP 70.3 Lautsprecher?

The V-Membrane Profile® from Hertz is a vital technological innovation of the Mille Pro MP 70.3 midrange driver. It consists of a membrane made from pressed cellulose, reinforced with cotton fibers, which guarantees both stiffness and lightness. This construction allows for an extended frequency response and contributes to excellent linearity. The structured shape of the membrane optimizes the radiation behavior in the mid to high frequency range, ensuring remarkable sound detail fidelity, ideal for demanding musical representations.

Welche Vorteile bietet die duale Neodym-Magnetstruktur im Mille Pro MP 70.3?

The dual neodymium magnet structure of the Mille Pro MP 70.3 offers numerous advantages, including a stronger magnetic force compared to conventional magnetic materials. Developed with FEM simulations, it ensures outstanding dynamics and precise control. This technology enhances the speaker's performance by increasing accuracy and efficiency, especially at higher volumes, without distortion. The result is a midrange driver that creates excellent acoustic experiences despite its compact size, even in demanding audio environments.

Wie beeinflusst die Schwingspule des Mille Pro MP 70.3 die Klangqualität?

The 20 mm CCAW dual-layer voice coil of the Mille Pro MP 70.3 by Hertz is mounted on a polyamide carrier, which significantly influences sound quality. This construction allows for exceptional thermal resilience while greatly reducing compression effects. The voice coil offers high efficiency in converting electrical signals into acoustic output, ensuring that even the finest musical details are preserved. The 8 decompression holes in the polyamide carrier also help reduce mechanical resonances, resulting in a clean, clear sound image.

Wie einfach ist die Installation des Mille Pro MP 70.3 in verschiedenen Audiosystemen?

The installation of the Mille Pro MP 70.3 is relatively straightforward due to its compact design. With a diameter of 70 mm and a total weight of only 0.17 kg, it fits easily into various audio systems. The removable rubber magnet cover minimizes the installation depth, which is advantageous when space is limited. Additionally, extensive mounting options are possible with the included protective grille. The physical dimensions A 87.8 mm, B 73 mm, C 50 mm, and D 44 mm provide flexibility in positioning in different vehicle types, making installation easier in both cars and home theater systems.

Welche Rolle spielt der akustisch transparente Aluminiumkorb des Mille Pro MP 70.3?

The acoustically transparent basket made of aluminum alloy of the Mille Pro MP 70.3 has several meanings. This design allows for unrestricted sound propagation and reduces enclosure interference. The aluminum basket is also robust and lightweight, which improves the structural integrity of the speaker and minimizes vibrations. An aesthetically pleasing appearance is provided by the elegant diamond cut and the embedded Hertz logo, which not only looks aesthetic but also emphasizes the high-quality character of the product. An additional advantage is the protection against dust and mechanical damage.

Wie beeinflusst das V-cone®-Profil das Abstrahlverhalten des Mille Pro MP 70.3?

The V-cone® profile of the Mille Pro MP 70.3 speaker significantly contributes to improving the radiation behavior. It optimizes sound distribution so that frequencies can be heard more evenly and clearly over a wider angle. This is particularly important in an environment where listeners are not positioned directly in the center of the sound field. The structure of the V-cone® profile works together with the 'Boundary Free' surround to enhance tonal consistency and precision, thereby creating an immersive listening experience that meets even the most demanding audiophile requirements.

Welche spezifischen Materialien werden für die Membran des Mille Pro MP 70.3 verwendet und warum?

The membrane of the Mille Pro MP 70.3 is made from pressed cellulose that is reinforced with cotton fibers. This choice of material provides an excellent balance between stiffness and lightness, which in turn allows for optimal frequency response and high sound linearity. Cotton fibers increase structural strength, while the cellulose maintains a certain flexibility that is necessary for dynamic sound reproduction. This combination enables the membrane to respond precisely to different frequency ranges, significantly improving overall sound quality and making the speaker well-suited for highly detailed musical playback.

Welche Akzente setzt der Mille Pro MP 70.3 Lautsprecher in Bezug auf Design und Funktionalität?

The Mille Pro MP 70.3 from Hertz combines functionality with an appealing design. The speaker is equipped with a basket made of aluminum alloy with diamond cut, which enhances both technical performance and aesthetic appeal. The recessed Hertz logo made of aluminum complements the striking appearance of the speaker. In terms of functionality, the removable metal grille provides protection and versatile installation options, while the rubber magnet cover minimizes disturbing vibrations.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
