    Frequently Asked Questions about Dieci DCX 690.3


    What is the power handling of the Dieci DCX 690.3 speaker?

    The Dieci DCX 690.3 from Hertz offers a continuous power handling of 90 Watts and reaches a peak value of up to 180 Watts. These power specifications ensure that the speaker can process even demanding audio signals without distortion. With an impedance of 4 Ohms and a depth of 98 mm, it fits ideally into many speaker enclosures and delivers a clear, powerful sound. The power handling is crucial for utilizing high-performance equalizer settings without overloading the speaker. Especially if you enjoy listening to music at high volumes, this coaxial speaker provides the right balance between power and precision.

    What is the frequency response of the Hertz Dieci DCX 690.3?

    The frequency response of the Dieci DCX 690.3 ranges from 45 Hz to 21 kHz, allowing it to cover a wide range of frequencies. This feature enables the speaker to reproduce both deep bass and high tones accurately. The frequency response is particularly relevant for music lovers who expect a balanced sound profile. The high-quality tweeter magnet made of high-density flux ferrite further contributes to sound quality, ensuring fine details in the upper frequency range. A wide frequency response makes the speaker versatile, whether for classical music or bass-heavy songs.

    What is the significance of the Thiele-Small parameters of the Dieci DCX 690.3?

    The Thiele-Small parameters of the Dieci DCX 690.3 provide valuable information about the behavior of the speaker and its performance in various enclosure situations. The Fs value of 66 Hz, for example, is the resonance frequency that determines how low the speaker can play. The Qts value of 1.12 indicates the total damping, while Qes and Qms describe the electrical and mechanical damping separately. With a Vas of 25.7 liters, you can estimate the required enclosure volume. These parameters are crucial for the optimal design and tuning of the speaker enclosure.

    What are the dimensions of the Dieci DCX 690.3?

    The Hertz Dieci DCX 690.3 has compact dimensions that allow for easy integration into various vehicle types and speaker openings. The overall diameters are 237 mm and 162 mm, while the installation range is specified as 224 mm and 153 mm. With a depth of 98 mm, the speaker can also be easily mounted in shallow installation locations. These measurements are particularly important if you plan to install the speaker in a vehicle with limited space. The installation process is simplified by these precise dimensions, allowing for solid placement.

    What does the magnet size mean for the Dieci DCX 690.3?

    The magnet size of the woofer in the Dieci DCX 690.3 is 80 x 40 x 15 mm, indicating the robustness and power of the magnet. A larger magnet can more effectively control the movements of the voice coil, resulting in better bass reproduction. Additionally, the use of a high-density flux ferrite magnet structure provides high magnetic strength and improved audio quality. The size and material choice of the magnet directly influence the efficiency and sound fidelity of the speaker. These features make the Dieci DCX 690.3 particularly interesting for music lovers who value detailed reproduction.

    How is the impedance of the Hertz Dieci DCX 690.3 measured and why is it important?

    The impedance of the Dieci DCX 690.3 is 4 Ohms, measured with a typical test signal. Impedance is a measure of the resistance that the speaker opposes to the flow of current. It is crucial for compatibility with amplifiers, as an amplifier with outputs that have a higher or equal impedance to the speaker should be used. Proper impedance matching ensures optimal sound and prevents damage to the amplifier or speaker. Many amplifier systems are designed for 4-ohm speakers like the Dieci DCX 690.3, allowing you to effectively integrate the speaker into an existing audio system.

    How does the voice coil affect the sound of the Dieci DCX 690.3 speaker?

    The voice coil of the Dieci DCX 690.3 has a diameter of 25 mm and is crucial for maintaining sound stability at various volume levels. It allows for precise movements of the diaphragm, ensuring more accurate sound reproduction. A larger voice coil improves the speaker's ability to achieve higher output levels without distortion. This is particularly important for reproducing complex audio signals, as the coil ensures smooth movements. Thus, it significantly contributes to sound quality and is ideal for speakers that are meant to provide both high fidelity and volume.

    What role does the material of the magnet play in the tweeters of the Dieci DCX 690.3?

    The tweeters of the Dieci DCX 690.3 use magnets made of high-density flux ferrite, which is crucial for sound quality. This type of magnet offers particularly good flux properties necessary for generating a strong and stable magnetic field. A strong magnetic field enhances the speaker's response and accuracy at high frequencies. This enables detailed and clear reproduction of high tones and fine sounds, which is especially important for enjoying high-quality music. The choice of this material is therefore intentional for sound optimization.

    How do the mechanical parameters affect the installation of the Hertz Dieci DCX 690.3?

    Mechanical parameters such as Cms, Mms, and BL of the Dieci DCX 690.3 are crucial for installation options and acoustic performance. Cms (Compliance) at 0.35 mm/N indicates the compliance of the diaphragm, while Mms (17.5 g) describes the moving mass that affects bass reproduction. The BL value of 3.9 T*m describes the magnetic driving force underlying precise and powerful diaphragm movement. These parameters determine how the speaker operates in various enclosure situations. Therefore, they are particularly important for users looking to optimize the installation situation and sound tuning.

    For which types of vehicles is the Dieci DCX 690.3 particularly suitable?

    Although the product description of the Dieci DCX 690.3 does not specify particular car brands, the dimensions and technical specifications are universally suitable for a variety of vehicle types. The speaker, with its 6"x9" dimensions and an installation depth of 98 mm, fits into many factory speaker openings, even in compact car designs. The flexible usability of the Dieci DCX 690.3 is facilitated by precise specifications for the overall and mounting diameter, 237 mm and 162 mm, respectively. Even in cars with limited space, it can be optimally integrated and provides full sound.
