Hertz DSK 165.3 6.5" 2-Way Component Car Speaker System
If you've been putting up with flat, lifeless sound from your factory speakers, the Hertz DSK 165.3 is the upgrade your car deserves. This 6.5" 2-way component system is built around Hertz's proven audio engineering — delivering crisp highs, detailed mids, and a soundstage that makes every drive feel like a private concert. At 160W peak power and 93dB sensitivity, it works brilliantly even with a modest head unit.
What is the Hertz DSK 165.3?
The Hertz DSK 165.3 is a 6.5-inch (165mm) 2-way component speaker system from Hertz's Dieci series. It pairs a woofer with an exclusive V-cone profile and a high-performance PEI membrane tweeter driven by a neodymium motor. The system includes a passive crossover filter integrated directly into the connection cables, making installation straightforward without compromising audio quality.

Advanced Technologies
V-cone® Woofer Profile: Hertz's proprietary V-cone design isn't just about looks — it's engineered to maintain accurate sound reproduction even when the speaker is not directly in front of you. This means the music sounds just as good whether you're the driver or a rear-seat passenger.
TPU (Thermoplastic Polyurethane) Surround: The surround is the ring that connects the cone to the speaker basket. Hertz uses TPU here because it stays flexible and consistent across temperature extremes — important in a car environment — while keeping resonance and distortion to a minimum even at high excursion levels.
Neodymium Motor Assembly: The tweeter uses a neodymium magnet, which is significantly stronger than conventional ferrite magnets at a fraction of the weight. This allows the tweeter to reproduce high frequencies with greater accuracy and reach further up the frequency range — up to 23kHz — for that airy, detailed top end.
PEI Membrane Tweeter: Polyetherimide (PEI) is a high-performance material used for the tweeter dome. It's rigid enough to maintain shape at high frequencies but light enough to respond quickly, resulting in smooth, fatigue-free treble that doesn't become harsh at higher volumes.
Cable-Integrated Passive Crossover: Rather than a bulky external crossover box, the DSK 165.3 integrates the hi-pass filter directly into the connection cables. This simplifies installation considerably and keeps the signal path clean.

Frequently Asked Questions
Q: What does the Hertz DSK 165.3 fit?
A: The DSK 165.3 is a standard 6.5" (165mm) component speaker. It fits most cars with a 6.5" door speaker location. Check your car's speaker size before ordering.
Q: Do I need an amplifier to run the Hertz DSK 165.3?
A: No. With 93dB sensitivity and 4 Ohm impedance, these speakers work well with a factory head unit. An amplifier will improve performance further but is not required.
Q: What is the difference between a component speaker and a coaxial speaker?
A: A component system has a separate woofer and tweeter, allowing you to position the tweeter at ear level for better soundstage and imaging. Coaxial speakers combine both in one unit. Component systems generally sound better.
Q: What is the RMS power of the Hertz DSK 165.3?
A: The continuous (RMS) power handling is 80W. The peak power is 160W.
Q: What is the frequency response of the DSK 165.3?
A: It covers 50Hz to 23,000Hz (23kHz), giving you solid bass extension and very detailed high-frequency reproduction.
Q: What is a V-cone woofer?
A: V-cone is Hertz's proprietary cone profile designed to maintain accurate sound reproduction at wide listening angles — so the music sounds great even when you're not sitting directly in front of the speaker.
Q: Is the crossover included with the Hertz DSK 165.3?
A: Yes. The passive hi-pass crossover filter is integrated directly into the connection cables, so no separate crossover box is needed.
