Hertz CPK 165 PRO 6.5-Inch 2-Way Component Speaker System
If you've been chasing that sweet spot between clarity and punch in your car audio setup, the Hertz CPK 165 PRO is worth a serious look. Built on the same DNA as the acclaimed Mille Pro line, this 6.5-inch component system brings studio-grade materials and thoughtful engineering into your car — without the complexity of a full custom build. Whether you're upgrading from factory speakers or stepping up from a basic aftermarket set, the CPK 165 PRO delivers a noticeable, immediate improvement in sound quality.
What is the Hertz CPK 165 PRO?
The Hertz CPK 165 PRO (model CPK 165) is a 2-way component speaker system from Hertz's Cento Pro series. It pairs a 165mm (6.5-inch) woofer with a 25mm Neodymium tweeter, connected through a 2-way passive crossover. The system is designed for car audio enthusiasts who want accurate, detailed sound reproduction across the full frequency range — from tight bass at 45Hz all the way up to airy highs at 22.5kHz. It handles up to 315W peak power and works with a standard 4 Ohm load, making it compatible with most aftermarket head units and amplifiers.

Advanced Technologies
Center Tuning Duct (CTD) Technology: The CP 25 tweeter uses a tunnel running through the centre of its Neodymium magnetic circuit. This duct allows cool air to circulate between the dome and the rear loading chamber, preventing heat build-up during extended listening sessions. The result is a very low resonance frequency for the tweeter, which in turn allows the crossover point to be set lower — improving the transition between woofer and tweeter and raising the perceived sound stage in your car.
Tetolon Fiber Dome: Both the tweeter dome and the woofer cone use Tetolon fiber — a material chosen for its combination of lightness and internal damping. Light materials move faster and respond more accurately to audio signals, while good damping prevents unwanted resonance peaks that colour the sound. The result is a speaker that sounds natural and balanced across the frequency range, rather than harsh or boomy.
Butyl Rubber Surround: The woofer uses a butyl rubber surround rather than the foam surrounds found on budget speakers. Butyl rubber is more resistant to UV, heat, and humidity — all conditions that are common inside a car. It also provides more consistent damping over time, meaning the speaker sounds as good after five years as it did on day one.
Mille Pro Cone Material: The cone material is carried over directly from Hertz's flagship Mille Pro series. This gives the CPK 165 PRO a level of cone rigidity and damping that is unusual at this price point, contributing to the tight, punchy bass response and clear midrange reproduction.

Frequently Asked Questions
Q: What does CPK 165 PRO mean?
A: CPK stands for the Cento Pro component kit. The 165 refers to the woofer diameter in millimetres (6.5 inches), and PRO indicates it belongs to the performance-oriented Cento Pro series.
Q: Will the Hertz CPK 165 PRO fit my car?
A: The woofer is a standard 165mm (6.5-inch) size, which fits the front or rear doors of most popular Indian cars including hatchbacks, sedans, and SUVs. Check your car's speaker location dimensions before purchasing.
Q: Do I need an external amplifier to run the CPK 165 PRO?
A: No. The system works with a standard aftermarket head unit. However, an external amplifier will allow you to take full advantage of the 315W peak power handling and get the best sound quality.
Q: What is the RMS power of the Hertz CPK 165 PRO?
A: The continuous (RMS) power handling is 105W. This is the power level the speaker can handle all day without damage. The 315W peak rating covers short transient bursts.
Q: What is the Center Tuning Duct technology?
A: It's a tunnel through the centre of the tweeter's Neodymium magnet that allows cool air to circulate around the dome. This keeps the tweeter thermally stable and lowers its resonance frequency, improving sound quality and longevity.
Q: Is the crossover included in the box?
A: Yes. The CPK 165 PRO comes with a 2-way passive crossover that splits the signal between the woofer and tweeter at 2.8kHz. No separate crossover purchase is needed.
Q: What is the impedance of the CPK 165 PRO?
A: The system is rated at 4 Ohm, which is the standard impedance for car audio and is compatible with all aftermarket head units and amplifiers.
Q: What is the sensitivity rating and why does it matter?
A: The sensitivity is 92.5dB SPL. A higher sensitivity means the speaker produces more volume from the same amount of power — so the CPK 165 PRO gets loud efficiently even with a modest head unit.
Q: What frequency range does the CPK 165 PRO cover?
A: It covers 45Hz to 22,500Hz, which spans from the upper bass range through to the very top of human hearing. This makes it a full-range component system for most music genres.
Q: Is the Hertz CPK 165 PRO the same as the Hertz Cento Pro CPK 165?
A: Yes, CPK 165 PRO and Cento Pro CPK 165 refer to the same product. Hertz uses both names in different markets and marketing materials.
Q: Does Dolphin Accessories provide a warranty on the Hertz CPK 165 PRO?
A: Yes. All Hertz products sold by Dolphin Accessories are 100% genuine and covered by the manufacturer's warranty. Contact us after your purchase for warranty assistance.
Q: How is the Hertz CPK 165 PRO different from the standard Hertz Cento CPK 165?
A: The PRO version uses upgraded materials inherited from the Mille Pro flagship line, including the Tetolon fiber cone and dome, butyl rubber surround, and the Center Tuning Duct tweeter technology — resulting in better damping, lower distortion, and a more refined sound compared to the standard Cento range.
