Frequently Asked Questions about Dieci DS 25.3

What is the power handling capacity of the Dieci DS 25.3 Subwoofer?

The Dieci DS 25.3 from Hertz has a continuous power handling capacity of 150 watts and a peak power of 600 watts. These power parameters allow the Subwoofer to produce stable and distortion-free sounds even with intense music pieces. Additionally, the special cooling system aids in heat dissipation, improving reliability at high power. The ferrite magnet structure with high flux density supports the efficient conversion of electrical energy into acoustic vibrations, which is particularly advantageous when used in sealed or reflex enclosures. These features make the Dieci DS 25.3 especially attractive to music lovers seeking powerful bass.

How large is the polypropylene membrane of the Dieci DS 25.3 Subwoofer?

The Dieci DS 25.3 Subwoofer from Hertz features a 10-inch (25 cm) membrane. This membrane is made of polypropylene with a mica additive, combining both stiffness and low weight. This combination is crucial for the precise reproduction of low frequencies with minimal distortion. This material choice ensures that the moving parts of the speaker can respond quickly and consistently to audio signals, which in turn improves sound quality, especially at low tones. Additionally, the butyl rubber surround allows for high excursion.

What impedance does the Dieci DS 25.3 have?

The Dieci DS 25.3 from Hertz has an impedance of 4 ohms. This impedance is well-suited for integration into common car audio systems, which often operate with this frequency voltage. Additionally, details such as the Re value of 3.3 ohms and the Le of 2.15 mH are important for better understanding the electrical characteristics of the speaker. With such designed electromechanics, it is ensured that the Subwoofer covers a wide frequency spectrum without overloading the car system with excessive power consumption, which is particularly beneficial during intensive use.

What frequency range does the Dieci DS 25.3 Subwoofer cover?

The frequency range of the Dieci DS 25.3 Subwoofer is between 32 Hz and 400 Hz. Within this spectrum, the Subwoofer delivers rich, voluminous bass and clear low tones. Especially at low frequencies, it is important that the diaphragm reacts quickly, which is ensured by the polypropylene material. The lower cutoff frequency of 32 Hz allows the Subwoofer to provide convincing sound quality even at very low bass levels, while the upper limit of 400 Hz ensures that transitional noises at higher frequencies do not occur and the playback remains clear.

How is the voice coil of the Dieci DS 25.3 designed?

The voice coil of the Dieci DS 25.3 from Hertz has a diameter of 38 mm, allowing for precise control of the diaphragm movement. The diameter is chosen to achieve an optimal balance between heat dissipation and electromagnetic force. This design ensures that even during prolonged operation, the temperature remains within a safe range without compromising performance. Due to the underlying mechanics of the voice coil, the Subwoofer can handle significant displacements without loss of sound integrity or efficiency, which is particularly important at high volumes.

How can the dimensions of the Dieci DS 25.3 be integrated into various car audio installations?

The Subwoofer Dieci DS 25.3 has impressive dimensions with an outer diameter (A) of 345 mm, a mounting depth (C) of 79 mm, and a mounting diameter (B) of 245 mm. These measurements make it a versatile choice for various vehicle configurations. If your car door width or trunk area meets these specifications, the Subwoofer can be easily installed. The installation does not require additional components, as the Dieci DS 25.3 is designed for installation in compact sealed or reflex enclosures, which is particularly advantageous in space-restricted environments.

What is special about the cooling system of the Dieci DS 25.3?

The cooling system of the Dieci DS 25.3 from Hertz is designed to efficiently dissipate the heat generated during operation to keep the components safe. The airflow through the structure is maximized, allowing the sensitive parts of the speaker, particularly the voice coil and the magnet, to maintain their function over a longer period without damage. This advanced cooling technology contributes to optimizing the reliability and longevity of the Subwoofer by preventing overheating and maintaining performance even under demanding conditions.

What role does the ferrite magnet play in the Dieci DS 25.3?

The Dieci DS 25.3 Subwoofer from Hertz is equipped with a high flux density ferrite magnet, measuring 100 x 50 x 25 mm. This type of magnet is known for its ability to maintain a strong magnetic field, which is crucial for controlling the movement of the diaphragm. Thanks to the high flux density, efficiency in converting electrical signals into acoustic energy is maximized. This not only means clearer and more powerful bass but also improved control and stability, minimizing distortion even at high volumes.

What are the Thiele-Small parameters of the Dieci DS 25.3?

The Thiele-Small parameters of the Dieci DS 25.3 from Hertz include important values such as the resonance frequency Fs of 36 Hz, the mechanical quality factor (Qms) of 5, the electrical quality factor (Qes) of 1.13, and the total quality factor (Qts) of 0.92. The Vas value of 34 liters determines the volume of the enclosure required to achieve optimal performance. These parameters are crucial for calculating and designing enclosures, as they describe the behavior of the Subwoofer at different frequencies and loads to achieve maximum sound performance.

What displacement does the Dieci DS 25.3 achieve?

The Dieci DS 25.3 Subwoofer exhibits remarkable mechanical properties with a maximum mechanical displacement (Xmech) of 16 mm and a maximum linear displacement (Xmax) of 9 mm. This means the Subwoofer can perform large diaphragm movements, which is particularly beneficial for reproducing extremely low frequencies. The butyl rubber surround minimizes distortion even at significant displacements. These mechanical properties ensure that the Subwoofer delivers consistent and clear bass both at low and high operating levels without sacrificing quality.
