Hertz CS 250 S2 10-inch 600W Peak 2 Ohm Car Subwoofer
If you want serious bass without sacrificing boot space, the Hertz CS 250 S2 is built exactly for that. Part of the Cento series, this 10-inch subwoofer punches well above its size — delivering tight, powerful low frequencies from enclosures as small as 16 litres. Whether you're upgrading a hatchback or building a dedicated audio setup, the CS 250 S2 gives you the authentic Hertz sound experience in a compact, installation-friendly package.
What is the Hertz CS 250 S2?
The Hertz CS 250 S2 (model S2250) is a 250 mm (10-inch) car subwoofer from the Cento series, designed for enthusiasts who want high-output bass from small sealed enclosures. It runs on a 2 Ohm single voice coil configuration, making it compatible with virtually any car amplifier on the market. Its compact magnetic group and reduced mounting depth mean it fits into tight spaces where most 10-inch subs simply won't go.

Advanced Technologies
Fluid Dynamic Optimisation System
At high excursion levels, air compression inside the enclosure can create unwanted noise and distortion. Hertz addressed this with a clever spider design that doubles as an air duct, channelling airflow through venting holes in the basket. The result is a dramatic reduction in turbulence-related distortion — something you'll notice immediately when the bass gets loud.
FEM-Simulated Cone and Suspension
The cone geometry, surround, and spider were all designed using Finite Element Method (FEM) computer simulations. This means every component is optimised to work together, maintaining control and minimising breakup even when the driver is pushed to its mechanical limits. You get cleaner bass at higher volumes compared to conventionally designed drivers.
Six-Layer Voice Coil Cooling
The 35 mm voice coil is wound in six layers of pure copper on a glass fibre former with high thermal resistance. This construction dissipates heat far more effectively than a standard two or four-layer coil, keeping operating temperatures in check during extended listening sessions at high acoustic pressure.
Compact Sealed Enclosure Optimisation
The electroacoustic parameters of the CS 250 S2 have been specifically tuned for sealed boxes starting from 16 litres. The absence of a rear decompression hole means the enclosure can be built to follow the exact contours of the subwoofer, saving precious space in the boot without compromising bass quality.
