More about the product
The Hertz CG100 is a high-quality coaxial woofer grille designed to protect and enhance Cento series speakers. Built from high-resistance ABS with a refined metal finish, this grille combines durability with a stylish look that complements any installation. It is specifically engineered for Hertz Cento coaxial woofers, ensuring a perfect fit and reliable protection without affecting sound performance.
The CG100 includes a removable metallic mesh that adds an extra layer of defence for the speaker cone. This mesh prevents accidental damage from objects while allowing airflow to maintain accurate sound reproduction. The open design ensures that audio remains clear and dynamic, so the speaker performs at its best while staying protected.
Installation is simple thanks to its precise fit for Cento coaxial woofers. The robust ABS structure resists wear and tear, making it suitable for vehicles where speakers may be exposed to potential impacts. The metal finish adds a premium touch, giving the audio system a clean and professional appearance.
The CG100 is ideal for those who want to keep their speakers safe without compromising aesthetics or performance. It is a practical solution for maintaining the condition of coaxial woofers in demanding automotive environments. While it does not improve audio output, its primary role is to protect and preserve the investment in a quality sound system.
Durable materials and thoughtful design make the CG100 a reliable accessory for long-term use. For anyone who values both function and style, the CG100 delivers a perfect combination of protection and elegance.
