Frequently Asked Questions about Dieci DCX 100.3

What is the power handling of the Hertz Dieci DCX 100.3 speaker?

The Hertz Dieci DCX 100.3 speaker has a nominal power handling of 30 watts and a peak power handling of 60 watts. These power handling values are crucial for selecting a suitable amplifier. It is recommended to use an amplifier that does not exceed the nominal power handling to avoid overloading the speaker. Especially regarding the peak power handling, you should ensure that the amplifier can handle short-term power spikes to fully utilize the sound performance of the 4" coaxial speaker.

What is the impedance of the Hertz Dieci DCX 100.3?

The impedance of the Hertz Dieci DCX 100.3 is 4 ohms. This impedance is typical for many car speaker systems. It is important that the amplifier or car radio operates with a 4-ohm impedance to ensure optimal power output. If the amplifier's impedance is unsuitable, it can lead to reduced sound quality or even damage to the speaker. When installing in an existing system, you should ensure that impedance compatibility is maintained to avoid affecting the sound quality.

What are the dimensions of the Hertz Dieci DCX 100.3 speaker?

The Hertz Dieci DCX 100.3 has specific dimensions that need to be considered during installation: The diameter is 100 mm, while the cutout size is 94 mm. The mounting depth is 50 mm, which is important to know if you want to fit the speaker into tight installation spaces. The distance from hole to hole is defined as 129 mm. These dimensions are crucial to ensure full compatibility with the speaker mount in your vehicle.

What are the Thiele-Small parameters of the Hertz Dieci DCX 100.3?

The Thiele-Small parameters of the Hertz Dieci DCX 100.3 are as follows: The DC resistance Re is 3.3 Ohms. The resonance frequency Fs is 115 Hz, indicating the lowest frequency the speaker can produce with its own resonance. The equivalent volume Vas is 1.7 liters and the moving mass Mms is 5.0 grams. The compliance coefficient Cms is 0.38 mm/N, while the mechanical efficiency BL is 3.5 T*m. The total quality factor Qts is 0.79, the electrical quality factor Qes is 0.96, and the mechanical quality factor Qms is 4.33.

What frequency range does the Hertz Dieci DCX 100.3 cover?

The Hertz Dieci DCX 100.3 coaxial speaker offers an impressive frequency range of 70 Hz to 21 kHz. This means it is capable of producing both deep bass and high frequencies, ensuring a balanced sound profile. The lower limit of 70 Hz ensures that the speaker can also deliver deep tones well, while the upper range of 21 kHz is suitable for reproducing the finest highs in musical pieces. Perfect for a wide variety of music genres.

How does the high-density flux ferrite magnet affect the sound of the woofer in the Hertz Dieci DCX 100.3?

The use of a high-density flux ferrite magnet in the woofer of the Hertz Dieci DCX 100.3 enhances excellent bass reproduction through targeted magnetic field control. This material choice provides an optimized magnetic field that allows for precise control and movement of the diaphragm. This results in precise and powerful bass reproduction, which is particularly advantageous in music genres with strong bass. Together with the water-resistant pressed paper diaphragm, it creates a powerful yet resonance-free sound character.

What materials are used in the Hertz Dieci DCX 100.3 speaker?

The Hertz Dieci DCX 100.3 uses exclusive materials for its construction. The woofer consists of a water-repellent pressed paper membrane, making it particularly resistant to moisture. A neodymium magnet in the tweeter ensures precise and clear high-frequency reproduction. The dome is made of polyetherimide (PEI), an industrial thermoplastic polymer that combines high strength and stability with excellent damping properties. This combination of materials allows the speaker to reproduce a wide frequency spectrum clearly and without distortion.

What tips are there for installing the Hertz Dieci DCX 100.3 in the car?

When installing the Hertz Dieci DCX 100.3, the specific dimensions of the speaker should be taken into account. With a diameter of 100 mm and a mounting depth of 50 mm, it is important that the installation location provides enough space. Make sure that the cutout size is 94 mm and the hole-to-hole measurement is 129 mm. The speaker should be securely mounted to avoid vibrations and any impairment of sound quality. Additionally, a correct impedance connection with the amplifier must be ensured.

How heavy is the Hertz Dieci DCX 100.3 speaker?

The Hertz Dieci DCX 100.3 speaker weighs 0.45 kg. This relatively low weight contributes to its ease of installation and exerts less stress on the corresponding mounting points in the vehicle. When mounting in mobile applications, such as in doors or dashboards, weight is a factor that can play a role in planning. A lower weight can help keep your vehicle's fuel consumption low without compromising sound quality.

What sound pressure level is achieved by the Hertz Dieci DCX 100.3?

The Hertz Dieci DCX 100.3 achieves a sound pressure level of 92 dB. This means that the speaker can produce considerable volume even at low amplifier power, making it ideal for use in loud environments like the vehicle interior. A higher sound pressure level indicates increased efficiency of the speaker, which is why this speaker can deliver excellent acoustic performance even with lower input power. Under optimal installation and connection conditions, you can enjoy an outstanding sound experience.

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
