Hertz DS 25.3 10-Inch 600W Peak 4 Ohm Car Subwoofer
If you've been chasing that deep, room-filling bass in your car without the distortion that usually comes with it, the Hertz DS 25.3 is worth a serious look. This 10-inch subwoofer is built for enthusiasts who want real performance — not just loud, but clean, controlled, and punchy bass that holds up even at high volumes.
What is the Hertz DS 25.3?
The Hertz DS 25.3 is a 10-inch (250mm) car audio subwoofer from Hertz's DS (Dieci Series) lineup. It's designed to deliver high-excursion bass with minimal distortion, handling up to 600W peak power at 4 Ohm impedance. With a polypropylene cone reinforced with mica injection and a butyl rubber surround, it moves a lot of air efficiently — which is exactly what you want from a subwoofer. The built-in cooling system keeps temperatures in check during extended listening sessions, making it a reliable long-term addition to any car audio setup.

Advanced Technologies
Polypropylene Cone with Mica Injection: The cone is the heart of any subwoofer — it's what moves the air and creates the sound. Hertz uses a polypropylene cone reinforced with mica particles, which makes it stiffer and lighter than a standard polypropylene cone. A stiffer cone resists flexing at high volumes, which means the bass stays tight and accurate even when you're pushing the amplifier hard.
Butyl Rubber Surround: The surround connects the cone to the basket and allows it to move back and forth. Butyl rubber is more durable and more flexible than foam surrounds, which means it can handle longer excursion (deeper cone travel) without cracking or tearing over time. This directly contributes to the DS 25.3's ability to produce deep, extended bass.
High-Density Flux Ferrite Magnet: The magnet system drives the voice coil and controls how the cone moves. Hertz uses a high-density ferrite magnet that provides a strong, consistent magnetic field. This translates to better control over the cone at all power levels — the bass stays punchy and defined rather than loose and boomy.
Integrated Cooling System: Heat is the enemy of any speaker, especially subwoofers that run at high power for extended periods. The DS 25.3 includes a dedicated cooling system that channels airflow around the voice coil, keeping temperatures down and protecting the driver during long listening sessions or high-power use.

Frequently Asked Questions
Q: What amplifier power do I need for the Hertz DS 25.3?
A: The DS 25.3 has a continuous (RMS) rating of 150W at 4 Ohm. For best results, pair it with an amplifier that delivers between 100W and 200W RMS at 4 Ohm. You can push it up to 600W peak, but sustained power above 150W RMS may shorten its lifespan.
Q: Is the Hertz DS 25.3 a sealed or ported subwoofer?
A: The DS 25.3 is a raw subwoofer driver — it does not come with an enclosure. It can be installed in either a sealed or ported box depending on your preference. Sealed enclosures give tighter, more accurate bass; ported enclosures give louder, deeper bass.
Q: What box size does the Hertz DS 25.3 need?
A: Hertz recommends consulting their official enclosure specifications for the DS 25.3. As a general guide, a sealed box of around 20–25 litres works well for most installations. Check the Hertz DS 25.3 datasheet for exact Vas, Qts, and Fs parameters.
Q: Can I wire two Hertz DS 25.3 subwoofers together?
A: Yes. Two 4 Ohm subwoofers can be wired in series (8 Ohm total) or in parallel (2 Ohm total), depending on your amplifier's stable impedance rating. Always check your amplifier's minimum impedance before wiring in parallel.
Q: Is the Hertz DS 25.3 good for music or just for loud bass?
A: It's genuinely good for music. The polypropylene + mica cone and butyl surround give it a controlled, accurate sound character. It's not a one-trick boom box — it handles everything from hip-hop and EDM to rock and jazz with clarity.
Q: What is the frequency response of the Hertz DS 25.3?
A: The DS 25.3 has a frequency response of 32 Hz to 400 Hz. The lower end (32 Hz) covers deep sub-bass, while the upper range (up to 400 Hz) gives you flexibility when setting your amplifier's low-pass crossover point.
Q: Does the Hertz DS 25.3 come with a warranty in India?
A: Yes, Hertz products sold through authorised dealers like Dolphin Accessories come with the manufacturer's warranty. Please contact us after purchase for warranty registration and support details.
Q: What does Xmech 16mm mean for this subwoofer?
A: Xmech refers to the maximum mechanical excursion — how far the cone can physically travel before it hits its limits and risks damage. At 16mm, the DS 25.3 has a reasonably long throw for a 10-inch driver, which contributes to its ability to produce deep, high-volume bass.
Q: Is the Hertz DS 25.3 compatible with my car?
A: The DS 25.3 is a universal 10-inch subwoofer driver. It is compatible with any car as long as you have a suitable enclosure and a compatible amplifier. It does not require any vehicle-specific mounting bracket.
Q: What is the difference between the Hertz DS series and the Hertz ES or HX series?
A: The DS (Dieci Series) is Hertz's entry-to-mid-level performance range, offering excellent value for enthusiasts. The ES (Energy Series) and HX (High Energy Series) sit higher in the lineup with more advanced materials and higher power handling. The DS 25.3 is a great starting point for a serious Hertz system.
Q: Can I use the Hertz DS 25.3 without a dedicated subwoofer amplifier?
A: Technically possible if your head unit or amplifier has a subwoofer output, but not recommended. The DS 25.3 performs best when driven by a dedicated mono or multi-channel amplifier with proper gain and crossover settings. A dedicated amp will unlock its full potential.
Q: How do I order the Hertz DS 25.3 from Dolphin Accessories?
A: Simply add it to your cart and check out. We offer pan-India delivery with secure packaging. If you have any questions about compatibility or installation before ordering, reach out to our team — we're happy to help.
