Hertz CX 100 | Cento Series 4" 2-Way Coaxial Speakers
The Hertz CX 100 is a masterpiece of compact engineering, designed to bring high-fidelity audio to even the smallest factory mounting locations. While 4-inch speakers often struggle with harshness or lack of detail, the Cento series solves this using a Tetolon® dome tweeter and a specialized Mica-reinforced cone. These materials allow the CX 100 to produce a "big" sound with refined musicality that belies its small footprint.
Product Highlights
-
Tetolon® Fiber Soft Dome: The 24 mm (0.9 in.) tweeter uses a soft fiber material to deliver a smooth, natural high-frequency response—avoiding the metallic "ringing" typical of budget speakers.
-
Mica-Reinforced Woofer (SPP-M): The Semi Pressed Paper-Mica cone provides the perfect balance of lightweight agility and rigid damping for clear, punchy midrange.
-
Optimized for Real-World Cabinets: Engineered specifically for the "unfavorable" placements found in many cars (like dashboards), ensuring a balanced soundstage even when off-axis.
-
High Efficiency: With a 92 dB sensitivity, these 4-inch drivers can get plenty loud while running off a standard factory radio or a small aftermarket amp.
Key Features
-
Rotatable Logo: The Hertz logo on the tweeter can be rotated to match the orientation of your installation for a professional look.
-
Neodymium Tweeter Magnet: Provides high magnetic flux in a tiny package, allowing the tweeter to remain compact while delivering superior detail.
-
Large 1" Woofer Voice Coil: A 25 mm voice coil provides better thermal management and power handling than standard 4-inch drivers.
-
High-Density Flux Ferrite Magnet: Ensures the motor has the "muscle" required to move the cone accurately for linear, distortion-free sound.
