Hertz C 165 | Cento Series 6.5" Woofer
The Hertz C 165 is a high-performance 165 mm (6.5") woofer designed to provide a perfect balance between natural sound quality and powerful output. As a cornerstone of the Cento series, it utilizes custom-engineered materials to ensure a smooth transition between mid-bass and midrange frequencies. It is the ideal choice for listeners looking to upgrade their front stage with a speaker that offers both high-fidelity clarity and the durability to handle high-volume playback.
Product Highlights
SPP-M (Semi Pressed Paper-Mica) Cone: Much time was invested in the research of the perfect material for the C 165. SPP-M was selected, which preserves the natural sound of semi-pressed paper and enhances it with Mica powder for improved rigidity. This results in an excellent balance between lightness and damping, essential for a powerful and controlled emission.
Oversized Ferrite Magnet: The motor assembly features an oversized high-density flux ferrite magnet that provides excellent control even during higher excursions. This ensures that the woofer remains linear and distortion-free during demanding musical passages.
High Sensitivity: With a rating of 93 dB SPL, the C 165 is remarkably efficient. This allows it to deliver a significant increase in volume and dynamic range, whether powered by a standard factory head unit or a dedicated high-power amplifier.
Xmech Capability: Designed with a mechanical excursion of 4.9 mm (0.19 in.), this woofer is built to move. This capability allows for an impactful mid-bass response that brings energy to your music without losing its musical composure.
Key Features
25 mm (1") Voice Coil: The high-energy voice coil is designed for thermal stability and high power handling, ensuring the speaker can perform reliably during long, demanding listening sessions.
Compact, Low-Resonance Basket: The basket geometry is optimized to provide maximum rigidity while remaining compact enough for easy installation in a wide variety of 6.5-inch factory door locations.
Weather Resistant: The treated paper cone and rugged materials are built to withstand the humidity and temperature changes common in the automotive environment, ensuring long-term performance and reliability.
System Versatility: While it excels as a standalone woofer in active setups, it is perfectly matched to be paired with Cento series tweeters and crossovers to create a high-end custom component system.
