More about the product
The Hertz C26 is a high-performance tweeter designed to deliver crisp, detailed high frequencies for car audio systems. Part of the Cento line, this model focuses on clarity and precision, making it an excellent choice for enhancing the upper range of music. The C26 features a 26 mm Tetolon fibre dome, which combines lightness and rigidity for accurate sound reproduction. This material helps reduce distortion and ensures smooth, natural treble tones.
The tweeter uses a powerful neodymium magnet that provides strong magnetic control in a compact design. This allows for efficient energy transfer and improved sensitivity, resulting in clear highs even at lower power levels. The C26 also includes a rear acoustic chamber, carefully engineered to extend the frequency response and improve linearity. This design ensures that the tweeter performs consistently across a wide range of listening conditions.
Installation is made simple with the supplied accessories. The C26 comes with flush, angled, and surface mounting options, giving flexibility for different vehicle interiors. Its compact size makes it easy to fit into tight spaces without compromising performance. The crossover filter is integrated into the wiring, which simplifies setup and ensures proper frequency distribution between the tweeter and midrange speakers.
The Hertz C26 is designed for those who want a balanced sound system where high frequencies are clear and detailed without being harsh. It pairs well with midrange drivers and subwoofers to create a full-spectrum audio experience. While it excels in clarity, it is not intended for extreme volume levels or competition setups. Instead, it focuses on musical accuracy and listening comfort.
Durability is another strength of the C26. The materials and design are built to withstand the demands of automotive environments, including temperature changes and vibrations. This makes it a reliable choice for long-term use. For anyone upgrading from factory tweeters, the C26 offers a noticeable improvement in sound quality, bringing out details in vocals and instruments that standard speakers often miss.
