Hertz DCX 690.3 – 6x9 Oval 3-Way Coaxial Car Speaker

If you've been living with factory speakers and wondering why your music sounds flat, the Hertz DCX 690.3 is the upgrade you've been looking for. This 6x9-inch 3-way coaxial from the Dieci series brings genuine audiophile character to your car — clear highs, a defined midrange, and bass that actually moves you. It's the kind of speaker that makes your daily commute feel like a private concert.

What is the Hertz DCX 690.3?

The Hertz DCX 690.3 is a 6x9-inch (230 x 152 mm) 3-way coaxial car speaker from Hertz's Dieci series. It combines a woofer, a 60mm midrange driver, and a PEI dome tweeter into a single unit, making it a straightforward drop-in replacement for most factory 6x9-inch speaker positions. With 180W peak power handling and a 4 Ohm impedance, it works well with both factory head units and aftermarket amplifiers.

Advanced Technologies

TPU (Thermoplastic Polyurethane) Surround: Unlike paper or foam surrounds that degrade over time, the TPU surround on the DCX 690.3 is built to last. It maintains consistent elasticity across temperature extremes — important in a car environment where temperatures can swing dramatically between seasons. The result is bass that stays tight and accurate year after year.

Oversized Magnetic Group: Hertz engineered the DCX 690.3 with a larger-than-typical magnet assembly. This increases the speaker's sensitivity, meaning it produces more volume from the same amount of power. In practical terms, you get a louder, more dynamic sound even when running off a standard factory head unit.

PEI Dome Tweeter: The polyetherimide (PEI) dome tweeter handles the high-frequency content — cymbals, vocal air, string harmonics — with a smooth, natural character. PEI is known for its ability to reproduce highs without the harshness that cheaper materials can introduce, making long listening sessions genuinely enjoyable.

60mm Midrange Driver: The dedicated midrange driver is what separates a true 3-way coaxial from a standard 2-way. Vocals, guitars, and instruments that live 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.

Frequently Asked Questions

Q: Will the Hertz DCX 690.3 fit my car's 6x9 speaker location?
A: The DCX 690.3 is designed for standard 6x9-inch (230 x 152 mm) cutouts. The mounting depth is 98mm, so check your door or rear deck cavity before installing. Most sedans, hatchbacks, and SUVs with factory 6x9 positions will accept it.

Q: Do I need an amplifier to run the Hertz DCX 690.3?
A: No. At 4 Ohm impedance, these speakers work directly with factory and aftermarket head units. An amplifier will improve performance, but it's not required to enjoy a significant upgrade over factory speakers.

Q: What is the RMS power of the DCX 690.3?
A: The continuous (RMS) power handling is 90W per speaker. The 180W 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 690.3 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 690.3 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, which gives you a cleaner, more detailed sound than a 2-way coaxial.

Q: What is the frequency response of the Hertz DCX 690.3?
A: The frequency response is 45Hz to 21,000Hz, covering deep bass through the upper limits of human hearing.

Q: Is the Hertz DCX 690.3 suitable for Indian weather conditions?
A: Yes. The TPU (Thermoplastic Polyurethane) surround is resistant to heat and humidity, making it a good choice for the temperature extremes common across India.

Q: What series does the DCX 690.3 belong to?
A: It belongs to the Hertz Dieci series, which is designed to deliver high-efficiency, wide-dispersion sound at an accessible price point within the Hertz lineup.

Q: Can I use the Hertz DCX 690.3 as rear deck speakers?
A: Yes, provided your rear deck has a 6x9-inch cutout and at least 98mm of mounting depth. They work equally well as front door or rear deck speakers.

Q: What is the impedance of the Hertz DCX 690.3?
A: The impedance is 4 Ohm, which is the standard for car audio and compatible with virtually all head units and amplifiers.

Q: How does the Hertz DCX 690.3 compare to factory car speakers?
A: Factory speakers are typically built to a cost target, not a sound quality target. The DCX 690.3 uses better materials — a ferrite magnet, TPU surround, PEI tweeter — and a true 3-way design that factory speakers rarely match. The difference 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.
