Frequently Asked Questions about Dieci DCX 130.3


What is the load capacity of the Dieci DCX 130.3 speaker?

The Dieci DCX 130.3 from Hertz offers a continuous load capacity of 40 watts and reaches a peak load of 80 watts. These values ensure that the speaker can efficiently handle both moderate and high audio signals. This peak load is crucial for applications where high power demands occur in short bursts. The load capacity is a key factor in ensuring the longevity of the speaker, as overloads can damage the mechanical components. Combined with its other technical features, the load capacity of the DCX 130.3 allows for versatile use in various audio systems.

What frequencies does the Dieci DCX 130.3 cover?

The frequency response of the Dieci DCX 130.3 ranges from 65 Hz to 21 kHz. With this range, the speaker covers a large part of the audible spectrum, particularly the important mid frequencies that are crucial for speech intelligibility and music recognition. The lower frequency range starts at 65 Hz, allowing for a solid bass response from a relatively compact 5-inch design. The upper frequencies reach up to 21 kHz, enabling the speaker to reproduce very high, clear, and precise tones. This technically broad coverage makes it ideal for reproducing detailed music and speech content.

What materials are used in the Dieci DCX 130.3?

The Dieci DCX 130.3 is equipped with a water-repellent press paper for the diaphragm, providing a good compromise between lightness and strength while also ensuring protection against moisture. The woofer uses a high-density flux ferrite magnet, which ensures powerful drive capability. A neodymium magnet is used for the tweeter, which, due to its low mass and high energy efficiency, is an ideal solution for the high-frequency range. This choice of materials is crucial for securing both sound quality and the longevity of the speaker.

What are the dimensions of the Dieci DCX 130.3 speaker?

The Dieci DCX 130.3 has a diameter of 130 mm (5 inches), making it ideally suited for many types of vehicles due to its common size. The installation depth is 59 mm, a crucial specification to ensure that the speaker fits properly into the intended mount. Other key dimensions include A3 at 151 mm and B at 116 mm, which ensure that the entire system can be integrated stably and securely at the installation site. The compact design facilitates a space-saving and straightforward installation while still ensuring comprehensive sound production.

How suitable is the Dieci DCX 130.3 for use in vehicles?

With a size of 130 mm and an installation depth of 59 mm, the Dieci DCX 130.3 is compatible for installation in a variety of cars. These coaxial speakers are designed to be installed in both standard car door openings and in other space-limited areas of a vehicle. The compact dimensions and design of the speaker allow for flexible installation, while the passive operation with 4 ohm impedance allows for seamless integration into existing car audio systems. The universal sizing and solid technical parameters ensure high compatibility and sound performance in the car.

What technical specifications does the diaphragm of the Dieci DCX 130.3 have?

The diaphragm of the Dieci DCX 130.3 is made of water-repellent pressed paper. This material choice provides both the flexibility and stability that are crucial for accurate sound reproduction across a wide frequency spectrum. The coating of the diaphragm prevents damage from moisture, which can be particularly significant in vehicle environments. In addition to water resistance, the diaphragm material impresses with its lightweight, positively affecting the responsiveness and overall acoustic performance of the speaker. This combination ensures an uncolored audio output under various environmental conditions.

What features do the magnets in the Dieci DCX 130.3 offer?

The Dieci DCX 130.3 from Hertz is equipped with high-density flux ferrite magnets for the woofer and neodymium magnets for the tweeter. These high-quality magnetic materials support the efficiency and sound quality of the speakers. Flux ferrite magnets provide robust bass reproduction, while neodymium magnets, known for their strength despite their smaller size, enable precise and clear high-frequency reproduction. This combination optimizes the speaker for balanced frequency coverage, intense bass, and sharp, detailed highs, which is crucial for versatile sound performance.

What are the Thiele-Small parameters of the Dieci DCX 130.3?

The DCX 130.3 from Hertz has the following Thiele-Small parameters: The electrical DC resistance Re is 3.3 ohms, the resonance frequency Fs is 82 Hz, and the equivalent volume Vas measures 7 liters. Furthermore, it has a moving mass Mms of 7.4 grams and a suspension compliance Cms of 0.51 mm/N. The force factor BL is 3.8 T*m, while the total quality factor Qts is 0.76. Additionally, the speaker shows an electrical quality factor Qes of 0.93 and a mechanical quality factor Qms of 4.3, which is important for comprehensive sound optimization.

How does the impedance of 4 ohms affect the Dieci DCX 130.3?

The impedance of 4 ohms in the Dieci DCX 130.3 ensures compatibility with a variety of common amplifiers and provides an ideal balance between power consumption and efficiency. A 4-ohm impedance allows the speaker to utilize greater power from amplifiers, which particularly ensures clearer and more powerful sound at average to high volumes. When selecting an amplifier, it is advisable to pay attention to the power ratings to avoid overloading while maximizing the speaker's full potential.

What dome does the Dieci DCX 130.3 use and what are its advantages?

The dome in the Dieci DCX 130.3 is made of polyetherimide (PEI). PEI is a thermoplastic polymer that offers high strength and temperature resistance, making it an ideal material for high-frequency domes. This material allows for detailed and accurate reproduction of high frequencies, which are responsible for sound brilliance and clarity. PEI domes tend to distort less than other materials and help maintain a clean sound dynamic even at high volumes. This is particularly advantageous in critical listening environments.
