Hertz Cento C 26 OE Datasheet

Frequently Asked Questions about Cento C 26 OE


What special features does the Cento C 26 OE Tweeter have?

The Hertz Cento C 26 OE is a Dome Tweeter with a 26 mm Soft Tetolon® diaphragm that enables detailed music reproduction. It features a strong neodymium magnet that ensures precise control at high loads in the mid-high frequency range. The faceplate geometry is optimized with FEM technology to ensure a linear frequency resonance, especially in off-axis installations. An important component is the crossover with a slope of 6 dB/Oct., which is also space-saving. This combination ensures optimal performance in OEM installation locations.

What does the frequency response of the Cento C 26 OE look like?

The frequency response of the Hertz Cento C 26 OE ranges from 1.8 kHz to 22.5 kHz. This range allows for the representation of fine tonal nuances and clear high-frequency reproduction. Thanks to the optimized faceplate geometry, the frequency response remains linear even in off-axis installations. This is particularly advantageous in vehicles, where sound often comes from a side or atypical direction. Additionally, the electro-acoustic specifications include a resonance frequency (Fs) of 1500 Hz, indicating that the Tweeter is specifically tuned for reproducing the upper frequency ranges.

What impedance does the Hertz Cento C 26 OE have?

The Hertz Cento C 26 OE Tweeter has an impedance of 4 Ohms. This impedance is optimal for operation with most Amplifiers found in modern audio systems and fits particularly well in OEM installation situations. Impedance plays a crucial role in how much power is drawn from an Amplifier, which in turn affects the efficiency and sound of the speaker. With its 4 Ohm impedance, the C 26 OE can operate effectively and help create a powerful sound experience without overloading the Amplifier.

How powerful is the Hertz Cento C 26 OE?

The Hertz Cento C 26 OE Tweeter has a high peak power of 120 watts. This high load capacity ensures powerful sound reproduction even at higher volumes, without compromising sound quality. It is particularly noteworthy that the load capacity of the tweeter has also been considered in the high-pass filtered mode (@ 2.5 kHz - 12 dB/Oct.), making it a robust addition to any speaker system. The voice coil with a diameter of 20 mm enhances performance by effectively managing heat generation during high power consumption.

What are the dimensions of the Hertz Cento C 26 OE?

The Hertz Cento C 26 OE Tweeter has compact dimensions that facilitate installation in OEM mounting locations. The physical specifications include a diaphragm size (D) of 26 mm, while other external dimensions are A 38.63 mm, B 33.33 mm, C 17.7 mm, and D 4.36 mm. These measurements describe the total space requirement, including the area for mounting screws, ensuring that the tweeter fits into various vehicle models. Its small size also makes installation easier in hard-to-reach areas of the vehicle interior.

How easy is it to install the Cento C 26 OE in a vehicle?

Thanks to its thoughtful design, the Cento C 26 OE from Hertz offers easy installation in common OEM mounting locations. The package includes a wide range of installation accessories that facilitate placement. The crossover with a slope of 6 dB/Oct. is space-saving and supports the installation process. Since the tweeter has a shallow mounting depth and weighs only 0.04 kg, it can be positioned flexibly. Especially in vehicle models that provide limited space, its compact design is an advantage.

What materials are used in the Cento C 26 OE Tweeter?

The Hertz Cento C 26 OE relies on proven quality materials to achieve excellent sound characteristics. The diaphragm is made of Soft Tetolon®, a material known for its lightness and stability, ensuring precise reproduction of musical details. The voice coil has a diameter of 20 mm and is made from high-quality materials that support optimal heat dissipation. Additionally, there is an extremely strong neodymium magnet that provides clear highs due to its strength. These materials harmonize perfectly for a detailed audio performance.

How does the Cento C 26 OE respond to different installation positions?

The Cento C 26 OE from Hertz is specifically optimized to deliver a consistent sound image in various installation positions. The faceplate geometry, developed using FEM technology, is designed to allow for linear frequency resonance even in off-axis installations. This is particularly advantageous when the speaker is installed in vehicles at less than ideal acoustic positions. Thus, the sound quality is maintained even when the tweeter is not directly aimed at the listener, allowing for flexible installation options.

What electro-acoustic properties does the Cento C 26 OE have?

The Hertz Cento C 26 OE features impressive electro-acoustic properties with a Re of 3.7 Ohms and a resonance frequency (Fs) of 1500 Hz. The inductance (Le) is 0.02 mH and the total quality factor (Qts) is 1.6. These parameters have been carefully tuned to enable precise yet powerful audio reproduction. Additional technical details such as the mechanical quality factor (Qms) of 2.9 and the electrical quality factor (Qes) of 3.5 show that clear priorities have been set on balance and clarity in the sound image.

Is the Hertz Cento C 26 OE compatible with common car brands?

The Cento C 26 OE is suitable for many common car brands due to its compact dimensions and universal design. With dimensions like A 38.63 mm, B 33.33 mm, C 17.7 mm, and D 4.36 mm, it is designed for OEM installation spaces, allowing for compatible installation in a variety of vehicle models. Even though no specific car brands are mentioned in the description, the comprehensive installation accessories allow for flexible adaptation. This feature makes it an ideal option for enhancing audio systems in various models.
