Frequently Asked Questions about Dieci DCX 87.3

What are the dimensions of the Hertz Dieci DCX 87.3 speaker?

The Hertz Dieci DCX 87.3 is a 3-inch (8 cm) coaxial speaker with a mounting depth of 45 mm. The speaker has a diameter of 87 mm, while the magnet measures 60 x 24 x 8 mm. If you are considering installing this speaker in your car, these compact dimensions are advantageous, especially if the mounting depth in your vehicle is limited or you want to place the speaker in a specific location. With its water-resistant pressed paper construction, you can also use the Dieci DCX 87.3 worry-free in more humid environments in the vehicle.

What power does the Dieci DCX 87.3 from Hertz provide?

The Hertz Dieci DCX 87.3 coaxial speaker offers a continuous power handling of 30 watts and can handle peak power of up to 60 watts. These features allow the speaker to deliver excellent performance in a variety of applications, both in everyday use and moderate audiophile settings. Listeners who enjoy clear, powerful sound will find the DCX 87.3 a reliable companion. The combination of a neodymium magnet in the tweeter and high-density flux ferrite in the woofer optimally supports this dynamic audio output.

What is the frequency range of the Hertz Dieci DCX 87.3?

The Hertz Dieci DCX 87.3 covers a frequency range from 130 Hz to 21 kHz. Within this spectrum, it provides clear reproduction of both low and high frequencies. The configuration of a woofer with a water-resistant pressed paper diaphragm and a tweeter with a PEI dome ensures balanced sound profiles. Particularly interesting is the high SPL value of 92 dB, which means that the speaker achieves high volume even at low power, making it ideal for use in vehicles without external amplifiers.

What are the Thiele-Small parameters of the Dieci DCX 87.3 speaker?

The Thiele-Small parameters of the Hertz Dieci DCX 87.3 include a resonance frequency (Fs) of 190 Hz, which affects the lower limit of the frequency range. Other important parameters are the equivalent volume (Vas) of 0.7 liters, the mechanical compliance (Cms) of 0.35 mm/N, and the total quality factor (Qts) of 1.0. Additionally, the speaker has a moving mass (Mms) of 2.0 g and a force factor (BL) of 2.5 T*m. This data is crucial for assessing the speaker's behavior in different enclosures.

Can the Dieci DCX 87.3 be installed in common car brands?

The Hertz Dieci DCX 87.3 speaker is designed with an 87 mm diameter and a mounting depth of 45 mm, making it suitable for installation in many common car models, provided the exact space conditions in the vehicle allow for it. The shallow mounting depth especially makes it compatible with vehicles where installation space is limited. It is important to ensure that the diameter fits into the designated speaker cutouts before installation to guarantee optimal performance.

How does the impedance of 4 ohms affect the Dieci DCX 87.3?

The impedance of 4 ohms in the Hertz Dieci DCX 87.3 allows the speaker to be effectively operated with most standard car radio systems, which typically require a 4-ohm load. This impedance ensures that the speaker interacts optimally with the system's electrical components, enabling efficient energy flow. The combination of 4 ohm impedance and 92 dB SPL ensures that the speaker delivers enough volume even at low amplifier power to provide an intense sound experience.

What materials are used in the production of the Dieci DCX 87.3?

The Hertz Dieci DCX 87.3 uses a membrane made of water-repellent pressed paper for its woofer, which increases durability and resistance to moisture. The tweeter consists of a PEI dome, which provides clearly defined high frequencies. The magnetic structure is made up of high-density flux ferrite in the woofer and neodymium in the tweeter. This combination of materials not only supports high-resolution sound but also the efficiency and durability of the speaker in demanding mobile environments.

How can the Hertz Dieci DCX 87.3 be optimally installed?

To optimally install the Hertz Dieci DCX 87.3, special attention should be paid to the installation locations that accommodate the 87 mm diameter and 45 mm installation depth. Start by checking the installation location in your vehicle to ensure there is enough space. Also, maintain the polarity of the connections to ensure the best possible sound reproduction. The water-repellent nature of the press paper also allows for installation in doors that are occasionally exposed to moisture, enabling flexible use in the automotive sector.

What advantages does the neodymium tweeter in the Dieci DCX 87.3 offer?

The use of a neodymium magnet in the tweeter of the Hertz Dieci DCX 87.3 provides various advantages, including lower weight and stronger magnetic force in a compact design. This contributes to a higher efficiency, which is particularly beneficial in vehicles that do not use external amplifiers. Neodymium also allows for precise high-frequency reproduction and improves the overall dynamics of the speaker. This tweeter is therefore ideal for listeners who prefer a crystal-clear sound profile without distortion even in the vehicle.

What significance do the Qts, Qes, and Qms values have in the Dieci DCX 87.3?

The Qts, Qes, and Qms values of the Hertz Dieci DCX 87.3 have significant implications for the behavior of the speaker. With a Qts of 1, the speaker shows a high level of control over its movements. The Qes value of 1.25 reflects the electrical damping, while the Qms value of 5.66 represents the mechanical damping. Together, these numbers provide a complete statement about the overall quality of the speaker, which is crucial when choosing the enclosure and tuning. An ideal understanding of these parameters can significantly improve sound quality.

Superlee
Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
