Frequently Asked Questions about Dieci DCX 170.3

What are the main technical details of the Dieci DCX 170.3 speaker?

The Dieci DCX 170.3 is a coaxial speaker from Hertz with a diameter of 6.5 inches. Its power specifications include a continuous power handling of 50 W and a peak power handling of 100 W. The speaker has an impedance of 4 Ohms and a mounting depth of 51 mm. It features a woofer voice coil with a diameter of 25 mm and uses high-density flux ferrite for the woofer magnet. The frequency response ranges from 60 Hz to 21 kHz, and the tweeter is equipped with a neodymium magnet. With a sensitivity of 93 dB, it offers excellent sound reproduction.

How does the impedance of the Hertz Dieci DCX 170.3 affect its use?

The Dieci DCX 170.3 speaker has an impedance of 4 Ohms, making it compatible with most car audio amplifiers that can support low impedances. An impedance of 4 Ohms is ideal for high-power applications, as it allows the speakers to draw more power, resulting in a louder and clearer sound. This is particularly beneficial if you enjoy listening to music at high volumes. The real DC component (Re) of the speaker is 3.6 Ohms, which should be considered in the calculation of the total system impedance.

What materials are used in the construction of the Dieci DCX 170.3 speaker?

The Hertz Dieci DCX 170.3 uses water-resistant pressed paper for the diaphragm, providing the speaker with excellent resistance to moisture, which is especially important in vehicle environments. The tweeter is made of PEI (Polyetherimide), known for its dimensional stability and good acoustic properties. The tweeter magnet is made of neodymium, a strong, lightweight material that allows for a high magnetic flux density. The woofer magnet is made of high-density flux ferrite, which ensures strong and consistent magnetic fields at a lower weight.

How is the frequency response of the Dieci DCX 170.3 defined?

The frequency response of the Dieci DCX 170.3 ranges from 60 Hz to 21 kHz, covering a wide range of tones, ideal for both deep bass and high frequencies. An optimal frequency response is crucial to ensure the quality of the reproduced sound, with both lower bass and higher treble being represented clearly and precisely. With a low Fs of 85 Hz, the speaker is capable of reaching lower frequencies, while the tweeter handles the upper frequencies. This allows the speaker to provide a complete sound spectrum.

What features does the woofer of the Dieci DCX 170.3 offer?

The woofer of the Dieci DCX 170.3 speaker includes a 25 mm voice coil, which plays a key role in producing low frequencies. The magnet, measuring 80 x 32 x 10 mm, has a high magnetic flux density, supported by flux ferrite, providing strong and efficient driving power for the speaker. The Mms of 8.8 g contributes to controlling the diaphragm movement, while the Cms of 0.4 mm/N ensures stable spring force. The Vas of 11.3 l indicates the sensitivity of the diaphragm in a closed box and supports powerful bass reproduction.

How do I install the Hertz Dieci DCX 170.3 in my car?

When installing the Dieci DCX 170.3, paying attention to the dimensions is crucial: with an overall diameter of 165 mm and a required installation depth of 51 mm, you should ensure that the installation location in the vehicle provides this space. The installation often takes place in the door panels or similar speaker cutouts. A diameter of the mounting holes of 140 mm allows for precise placement. Prefabricated mounts in door panels may need to be modified to ensure the optimal fit and secure a stable seating of the speaker.

Can the Dieci DCX 170.3 be operated with my amplifier?

With a continuous power handling of 50 W and a peak value of 100 W, the Dieci DCX 170.3 is compatible with many standard Amplifiers, provided the Amplifier can support the load of 4 Ohms. The BL factor of 3.7 T*m indicates the speaker's mobility and control, ensuring a quick response to electrical signals. The Qts of 0.95 shows the balance between electrical Damping and mechanical system constraints and is suitable for closed or bass-heavy adjustments. Just make sure that the resistance requirements are compatible.

What is the weight of the Dieci DCX 170.3 speaker?

Each Dieci DCX 170.3 speaker weighs 0.56 kg. This moderate weight not only allows for easy handling during installation but also minimizes the overall vehicle weight, which can slightly affect fuel consumption. A lightweight speaker also means less pressure is exerted on the mounting points, increasing the durability of both the speakers and the mounting locations. This can be a crucial advantage, especially in vehicles designed to save weight.

What parameters influence the sound quality of the Dieci DCX 170.3?

The sound quality of the Dieci DCX 170.3 speaker is influenced by several parameters. The frequency response of 60 Hz to 21 kHz ensures clear and nuanced reproduction of both low and high tones. The Mms of 8.8 g controls the resonance characteristics, while the BL factor of 3.7 T*m relates to motion control. An SPL of 93 dB indicates high acoustic power. The Qms of 4.39 along with Qes of 1.21 produces the Qts of 0.95 and affects the overall resonance characteristics of the speaker.

How robust is the Dieci DCX 170.3 speaker against environmental influences?

The Dieci DCX 170.3 speaker is resistant to moisture and dust thanks to the water-repellent pressed paper membrane. This design minimizes the risk of moisture damage and material deformation, which is particularly important in vehicles exposed to changing weather conditions. Neodymium and flux ferrites as magnet materials ensure lasting magnetic strength and resistance to demagnetization. The use of PEI in the Tweeter provides additional resistance to temperature fluctuations, which is beneficial in both hot and cold climatic conditions.

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.
