More about the product
The Hertz C165 is a high-quality component subwoofer designed to deliver deep, accurate bass for car audio systems. Built with precision engineering, this model combines durability and performance for enthusiasts who want clean low-frequency sound without distortion. Its design features a semi-pressed paper cone reinforced with mica, which ensures rigidity while maintaining natural sound reproduction. This combination improves strength and reduces unwanted resonance, resulting in smooth and powerful bass notes.
The cone works with a high-density foam surround to allow controlled movement, producing accurate low frequencies. The Hertz C165 uses a ferrite magnet and a low-resonance basket structure to minimise vibrations. This design helps maintain clarity even at higher volumes. The subwoofer’s voice coil is optimised for heat dissipation, which improves reliability during extended listening sessions. With a frequency response tailored for low-end performance, the C165 adds depth to music without overpowering midrange tones.
Installation is straightforward thanks to its standard 165 mm size, making it compatible with many factory and aftermarket setups. The shallow mounting depth provides flexibility for vehicles with limited space. While the C165 excels in bass reproduction, it is best paired with an amplifier for optimal results. It does not include built-in amplification, so external power is required to achieve its full potential.
This model is part of Hertz’s Cento line, known for delivering premium sound at an accessible price point. It offers a balance between performance and affordability, making it a strong choice for those upgrading from factory speakers. However, it is not intended for extreme SPL setups or competition-level bass. Instead, it focuses on accurate, musical low frequencies suitable for everyday listening.
The Hertz C165 is ideal for creating a well-rounded audio system where bass complements rather than dominates. Its durable materials and thoughtful design ensure long-term reliability, even in demanding automotive environments. For those seeking a noticeable improvement in sound quality without sacrificing space or budget, the C165 stands out as a practical and effective solution.
