Hertz DCX 87.3 2-Way Coaxial 3.4" Peak 60W Car Speaker
Small speakers don't have to sound small. The Hertz DCX 87.3 proves that a compact 3.4-inch coaxial can deliver wide frequency response, clear highs, and genuine efficiency — qualities you'd normally expect from a much larger driver. If your car has 3.4-inch dash or door positions and you've been settling for factory audio, this is the upgrade that fits the space and transforms the sound.
What is the Hertz DCX 87.3?
The Hertz DCX 87.3 is a 3.4-inch (87mm) 2-way coaxial car speaker from Hertz's Dieci series. It pairs a woofer with a neodymium tweeter featuring Hertz's exclusive PEI dome, all in a compact unit designed for standard 87mm speaker positions. With 60W peak power handling, 30W RMS, and 4 Ohm impedance, it works with factory head units and aftermarket systems alike. Despite its small size, it uses an oversized magnetic group for efficiency and control that punches well above its dimensions.

Advanced Technologies
Neodymium Tweeter Magnet: Unlike the ferrite magnets used in most budget coaxials, the DCX 87.3's tweeter uses a neodymium (rare-earth) magnet. Neodymium delivers a significantly stronger magnetic field from a much smaller magnet, which is exactly what you need in a compact speaker where space is at a premium. The result is a tweeter that performs with authority despite the speaker's small overall size.
Exclusive PEI Dome Tweeter: Hertz's polyetherimide (PEI) dome is a signature feature across the Dieci series. PEI is a high-performance polymer that reproduces high frequencies with a smooth, natural character — no harshness, no listening fatigue. In a compact speaker like the DCX 87.3, where the tweeter does a lot of the heavy lifting for perceived clarity, this material choice makes a real difference to how the speaker sounds over long listening sessions.
Oversized Magnetic Group: Hertz engineered the DCX 87.3 with a magnet assembly that's larger than what you'd typically find in a 3.4-inch speaker. A bigger magnet means higher sensitivity — the speaker produces more volume from the same amount of power. In a compact installation where you can't always add an amplifier, this efficiency advantage means you get a louder, more dynamic result from your factory head unit.
Water-Repellent Paper Cone: The woofer cone is treated with a water-repellent coating that protects it from moisture, condensation, and humidity — all real concerns in a car environment. This treatment extends the speaker's lifespan and keeps the sound consistent regardless of the weather, which matters particularly in India's monsoon season and high-humidity regions.
Benefits

- ⚡ Works without an amplifier — plug straight into your head unit
- 📱 Compact and lightweight — easy to fit in tight dash or door positions
- 🎯 Neodymium tweeter delivers crisp highs even at low volume
- 📦 Sold as a pair — both positions covered in one purchase
Who Should Buy the Hertz DCX 87.3?
- Car owners with 3.4-inch (87mm) dash or door speaker positions looking for a genuine upgrade
- Anyone replacing small factory speakers that sound thin or lack clarity
- Drivers who want better high-frequency detail without adding a separate tweeter
- Those building a multi-speaker system where the DCX 87.3 handles dash or fill positions
- Enthusiasts who want a trusted European audio brand in a compact format
- Anyone running a factory head unit who wants more from their audio without an amplifier

Frequently Asked Questions
Q: What size is the Hertz DCX 87.3?
A: The DCX 87.3 is a 3.4-inch (87mm) speaker. It fits standard 87mm speaker cutouts commonly found in dash positions, A-pillars, and small door locations in many cars and hatchbacks.
Q: Do I need an amplifier to run the Hertz DCX 87.3?
A: No. At 4 Ohm impedance and with an efficient oversized magnet, these speakers work directly with factory and aftermarket head units. An amplifier will improve performance, but it's not required.
Q: What is the RMS power of the DCX 87.3?
A: The continuous (RMS) power handling is 30W per speaker. The 60W figure is the peak rating. Match your amplifier's RMS output to the speaker's RMS rating for best results.
Q: Is the Hertz DCX 87.3 sold as a pair or a single speaker?
A: It is sold as a pair — you receive two speakers in the box.
Q: What is the frequency response of the DCX 87.3?
A: The frequency response is 130Hz to 21,000Hz. This speaker handles midrange and high frequencies well. For deep bass, pair it with a subwoofer or a larger woofer in a multi-speaker setup.
Q: Why does the DCX 87.3 use a neodymium tweeter magnet?
A: Neodymium is a rare-earth magnet material that delivers a much stronger magnetic field than ferrite in a smaller size. In a compact speaker like the DCX 87.3, this allows the tweeter to perform with real authority without adding bulk to the overall unit.
Q: What is a PEI dome tweeter?
A: PEI stands for polyetherimide, a high-performance polymer that Hertz uses for its tweeter domes across the Dieci series. It reproduces high frequencies smoothly and naturally, without the harshness that cheaper dome materials can introduce.
Q: Is the Hertz DCX 87.3 suitable for Indian weather conditions?
A: Yes. The water-repellent paper cone is treated to resist moisture and humidity, making it a reliable choice across India's varied climate conditions including monsoon season.
Q: Can the DCX 87.3 be used as a fill speaker in a multi-speaker system?
A: Absolutely. Its compact size and wide high-frequency response make it an excellent fill or dash speaker in systems where larger woofers handle the bass and the DCX 87.3 covers the mids and highs.
Q: What is the impedance of the Hertz DCX 87.3?
A: The impedance is 4 Ohm, the standard for car audio, compatible with virtually all head units and amplifiers.
Q: How does the DCX 87.3 compare to factory 3.4-inch speakers?
A: Factory speakers in this size are typically very basic — small magnets, cheap dome materials, no water resistance. The DCX 87.3 uses an oversized ferrite magnet, a neodymium-backed PEI dome tweeter, and a water-repellent cone. The improvement in clarity and detail is immediately noticeable.
Q: Is this product genuine and covered by warranty?
A: Yes. Dolphin Accessories sells 100% genuine Hertz products sourced from authorised distributors. Warranty terms follow Hertz India's standard policy — contact us after purchase for warranty support.
