Hertz DCX 710.3 3-Way Coaxial 7x10 Oval Peak 300W Car Speaker
Most factory speakers are built to a budget, not a sound standard. The Hertz DCX 710.3 changes that. Slotting into the same 7x10-inch space as your stock speakers, it brings a level of clarity, depth, and efficiency that factory audio simply can't match. Whether you're on a long highway run or stuck in city traffic, this speaker makes the music worth listening to.
What is the Hertz DCX 710.3?
The Hertz DCX 710.3 is a 7x10-inch 3-way coaxial car speaker from Hertz's Dieci series. It combines a woofer, a dedicated 60mm midrange driver, and a PEI dome tweeter in a single unit — making it a direct replacement for most factory 7x10-inch speaker positions. With 300W peak power handling, 150W RMS, and 4 Ohm impedance, it performs well with both factory head units and aftermarket amplifiers.

Advanced Technologies
TPU (Thermoplastic Polyurethane) Surround: The TPU surround is one of the most durable materials used in car speaker construction. Unlike foam, which degrades in heat and humidity, TPU maintains its elasticity across the temperature extremes common in Indian conditions — from scorching summer afternoons to monsoon humidity. The result is bass that stays tight and accurate over years of use.
Oversized Magnetic Group: The DCX 710.3 uses a 90mm high-density ferrite magnet — larger than what you'd find in most speakers at this price point. A bigger magnet means higher sensitivity, so the speaker produces more volume from the same amount of power. In practice, this means a louder, more dynamic sound even when running off a standard factory head unit.
PEI Dome Tweeter: The polyetherimide (PEI) dome tweeter handles high-frequency content — cymbals, vocal air, string harmonics — with a smooth, natural character. PEI is known for reproducing highs without the harshness that cheaper materials introduce, making long listening sessions genuinely comfortable.
Dedicated 60mm Midrange Driver: This is what separates a true 3-way coaxial from a standard 2-way. Vocals, guitars, and instruments in the 500Hz–5kHz range are handled by this dedicated driver, keeping them clear and separate from the woofer and tweeter. The result is a more open, layered soundstage that you can actually hear the difference in.
Water-Repellent Paper Cone and Dome: Hertz treats the woofer cone and dome with a water-repellent coating, protecting them from moisture ingress — a real concern in car environments where condensation, rain, and humidity are constant factors. This extends the speaker's lifespan and keeps the sound consistent regardless of the weather outside.

Frequently Asked Questions
Q: Will the Hertz DCX 710.3 fit my car's 7x10 speaker location?
A: The DCX 710.3 is designed for standard 7x10-inch speaker cutouts. The mounting depth is 110mm, so check your door or rear deck cavity before installing. Most vehicles with factory 7x10 positions will accept it directly.
Q: Do I need an amplifier to run the Hertz DCX 710.3?
A: No. At 4 Ohm impedance, these speakers work directly with factory and aftermarket head units. An amplifier will improve performance further, but it's not required to enjoy a significant upgrade over factory speakers.
Q: What is the RMS power of the DCX 710.3?
A: The continuous (RMS) power handling is 150W per speaker. The 300W figure is the peak rating. For best results, match your amplifier's RMS output to the speaker's RMS rating.
Q: Is the Hertz DCX 710.3 sold as a pair or a single speaker?
A: It is sold as a pair — you receive two speakers in the box, enough for one set of front or rear positions.
Q: What makes the DCX 710.3 a true 3-way speaker?
A: It has three separate drivers — a woofer for bass, a dedicated 60mm midrange driver for vocals and instruments, and a PEI dome tweeter for high frequencies. Each driver handles its own frequency range, giving you cleaner, more detailed sound than a 2-way coaxial.
Q: What is the frequency response of the Hertz DCX 710.3?
A: The frequency response is 40Hz to 21,000Hz, covering deep bass through the upper limits of human hearing — wider than the DCX 690.3's 45Hz lower limit.
Q: Is the Hertz DCX 710.3 suitable for Indian weather conditions?
A: Yes. The TPU surround and water-repellent paper cone and dome are designed to handle heat, humidity, and moisture — all common challenges in Indian climates.
Q: What series does the DCX 710.3 belong to?
A: It belongs to the Hertz Dieci series, designed for high-efficiency, wide-dispersion sound at an accessible price point within the Hertz lineup.
Q: Can I use the Hertz DCX 710.3 as rear deck speakers?
A: Yes, provided your rear deck has a 7x10-inch cutout and at least 110mm of mounting depth. They work equally well as front door or rear deck speakers.
Q: What is the impedance of the Hertz DCX 710.3?
A: The impedance is 4 Ohm, the standard for car audio, compatible with virtually all head units and amplifiers.
Q: How does the Hertz DCX 710.3 compare to factory car speakers?
A: Factory speakers are built to a cost target. The DCX 710.3 uses better materials — a large ferrite magnet, TPU surround, PEI tweeter, water-repellent cone — and a true 3-way design. The difference in clarity and detail is immediately noticeable from the first listen.
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.
