Hertz CS 200 S4 8-Inch Car Subwoofer
If you want real bass in your car without sacrificing boot space or installation flexibility, the Hertz CS 200 S4 is built for exactly that. This 8-inch subwoofer from the Cento series punches well above its size — delivering tight, controlled low frequencies that you feel as much as you hear, all from a compact enclosure that fits where most subs simply won't.
What is the Hertz CS 200 S4?
The Hertz CS 200 S4 is an 8-inch (200mm) car audio subwoofer from the Cento series, rated at 150W RMS and 300W peak power with a 4 Ohm single voice coil impedance. It is specifically engineered to perform in sealed enclosures as small as 9.6 litres, making it one of the most installation-friendly subwoofers in its class. Every component — from the cone geometry to the magnetic group — has been designed and validated using advanced simulation software to ensure clean, powerful bass with minimal distortion.

Advanced Technologies
FEM (Finite Element Method) Optimisation: Hertz engineers used Finite Element Method simulations to design the cone geometry, suspension, and spider of the CS 200 S4. This computational approach identifies the ideal shape and stiffness for each component before a single prototype is built, resulting in a driver that maintains control and low distortion even when pushed to high mechanical excursion levels.
Fluid Dynamic Optimisation System: At high excursion levels, air trapped inside a subwoofer basket can compress and create unwanted acoustic distortion. Hertz addressed this with a clever solution — the spider support doubles as an air duct, channelling air towards venting holes in the basket. This dramatically reduces the turbulence and compression that would otherwise colour the bass output.
Six-Layer Voice Coil with Active Cooling: The 35mm voice coil is wound across six layers of pure copper on a glass fibre former with high thermal resistance. This construction increases the surface area available for heat dissipation, keeping the coil temperature within a safe operating range even during extended high-volume listening sessions — a common failure point in lesser subwoofers.
Compact Magnetic Group Design: The magnetic assembly has been kept deliberately compact, with no rear decompression hole required. This means the enclosure can be built to closely follow the shape of the subwoofer itself, achieving an overall installation depth that is barely larger than the driver — a significant advantage in space-constrained vehicles.

Frequently Asked Questions
Q: What size enclosure does the Hertz CS 200 S4 need?
A: It is designed to work in sealed enclosures starting from just 9.6 litres (0.33 cubic feet), which makes it one of the most compact-enclosure-friendly 8-inch subwoofers available.
Q: What amplifier power do I need for the Hertz CS 200 S4?
A: The CS 200 S4 handles 150W RMS continuously. For best results, pair it with an amplifier that delivers between 100W and 150W RMS at 4 Ohms. Avoid underpowering it significantly, as that can cause clipping distortion.
Q: Is the Hertz CS 200 S4 suitable for a ported enclosure?
A: Hertz has optimised this subwoofer specifically for sealed enclosures. While it may work in a ported box, the electroacoustic parameters are tuned for sealed use, so a sealed enclosure will give you the most accurate and controlled bass response.
Q: What does single voice coil (SVC) mean?
A: A single voice coil means the subwoofer has one set of winding terminals. This gives you a fixed impedance of 4 Ohms, which simplifies amplifier matching and wiring compared to dual voice coil designs.
Q: Can I use the Hertz CS 200 S4 without an amplifier?
A: No. Like all aftermarket subwoofers, the CS 200 S4 requires a dedicated external amplifier. It cannot be driven directly from a head unit's built-in output.
Q: Does the Hertz CS 200 S4 come with a grille?
A: The subwoofer includes an ABS plastic gasket for a clean installation finish. The black metal mesh grille with the Hertz diamond aluminium logo is an optional accessory sold separately.
Q: What cable size should I use to wire the Hertz CS 200 S4?
A: The terminal block accepts cables up to 8 AWG. Using thicker cable (lower AWG number) reduces wiring resistance and is especially beneficial in multi-subwoofer installations.
Q: Is the Hertz CS 200 S4 compatible with my car?
A: The CS 200 S4 is a universal-fit subwoofer — it is not vehicle-specific. It will work in any car as long as you have a suitable sealed enclosure and a compatible amplifier. Contact us if you need help planning your installation.
Q: What is FEM optimisation and why does it matter?
A: FEM stands for Finite Element Method — a computer simulation technique that Hertz uses to model how the cone, suspension, and spider behave under real operating conditions. This allows engineers to optimise every component before manufacturing, resulting in lower distortion and more consistent performance.
Q: How does the fluid dynamic optimisation system work?
A: At high excursion levels, air inside the basket can compress and create distortion. Hertz designed the spider support to act as an air duct, directing air through venting holes in the basket. This reduces turbulence and compression, keeping the bass clean even at high volume.
Q: Is the Hertz CS 200 S4 a genuine Hertz product?
A: Yes. Dolphin Accessories sources all Hertz products from authorised distributors. Every unit is 100% genuine and covered by the manufacturer's warranty.
Q: What is the difference between RMS power and peak power?
A: RMS (Root Mean Square) power — 150W in this case — is the continuous power the subwoofer can handle safely over time. Peak power (300W) is the maximum it can handle in short bursts. Always match your amplifier to the RMS rating, not the peak figure.
