The \u003cstrong\u003eHertz X 165 6.5\" Coaxial Car Speakers\u003c\/strong\u003e are built for drivers who want real sound — clear, punchy, and distortion-free — without tearing apart their car for a complicated install.

It's built to drop straight into your factory speaker slot — no cutting, no fabrication. Inside, you get a neodymium tweeter and a high-sensitivity woofer working together in one compact DIN-size basket. It handles \u003cstrong\u003e55W RMS continuously\u003c\/strong\u003e and peaks at \u003cstrong\u003e220W\u003c\/strong\u003e at \u003cstrong\u003e4 Ohm\u003c\/strong\u003e, so it works great even with a stock head unit.\u003c\/p\u003e\n\u003ch2\u003eWhy Choose the Hertz X 165?\u003c\/h2\u003e\n\u003cp\u003eFactory speakers are made cheap — that's just the reality. The Hertz X 165 is the fix. Whether you're stuck in city traffic or cruising on the highway, these speakers bring out the detail in your music that your stock setup was hiding. The tweeter faceplate is specially shaped so the sound stays balanced even when the speaker is angled away from you — which is exactly how door speakers are mounted in most cars.

Hertz uses it in the 24 mm tweeter so it can be small and light while still driving the dome with plenty of force — giving you crisp, detailed highs without a bulky tweeter assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePEI Dome Tweeter Diaphragm:\u003c\/strong\u003e PEI (Polyetherimide) is a tough, heat-resistant plastic that's also great for audio. It's stiff enough to move air accurately at high frequencies but doesn't add the metallic edge you get from aluminium or titanium domes. The result is smooth, natural-sounding highs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWater-Repellent Pressed-Paper Cone:\u003c\/strong\u003e The woofer cone is treated to push moisture away — important for door speakers that deal with humidity every day. This keeps the cone stiff and consistent so the sound doesn't change as the speaker ages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh Flux Density Ferrite Magnet:\u003c\/strong\u003e The 80 mm ferrite magnet keeps a strong, steady magnetic field around the 25 mm voice coil. More flux density means faster, tighter bass response and less distortion when you push the volume up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFoam Surround:\u003c\/strong\u003e Foam lets the cone move freely while keeping it controlled. It's more flexible than rubber, which means better sensitivity (more volume from less power) and deeper bass — both at the same time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDIN-Standard Basket:\u003c\/strong\u003e DIN sizing is the global standard for factory speaker dimensions. The X 165 basket is built to these specs so it fits most OEM cutouts without any modification.

The 4 Ohm impedance and 55W RMS rating match what factory head units put out. You'll hear a clear improvement in sound quality straight away, no amplifier needed.\u003c\/p\u003e\n\u003ch3\u003eQ2: What size are the Hertz X 165 speakers?\u003c\/h3\u003e\n\u003cp\u003eThey're 6.5 inches (165 mm) in diameter and use a standard DIN-size basket, so they fit most factory 6.5\" speaker slots in cars, SUVs, and MPVs.\u003c\/p\u003e\n\u003ch3\u003eQ3: Do I need an amplifier?\u003c\/h3\u003e\n\u003cp\u003eNo. These speakers run fine off a stock head unit. If you do add an amplifier later, you'll unlock the full 220W peak and get even more out of them.\u003c\/p\u003e\n\u003ch3\u003eQ4: What's the difference between 55W RMS and 220W peak?\u003c\/h3\u003e\n\u003cp\u003eRMS (55W) is the power the speaker handles continuously — that's the number that matters for everyday use. Peak (220W) is the maximum it can take in short bursts during loud moments in music. Match your amp to the RMS figure, not the peak.\u003c\/p\u003e\n\u003ch3\u003eQ5: Why neodymium for the tweeter magnet?\u003c\/h3\u003e\n\u003cp\u003eNeodymium is much stronger than ferrite for its size. That means a smaller, lighter tweeter that still drives the dome with plenty of force — giving you detailed, accurate highs without a big, bulky tweeter housing.\u003c\/p\u003e\n\u003ch3\u003eQ6: What does off-axis performance mean in practice?\u003c\/h3\u003e\n\u003cp\u003eIt means the sound stays balanced even when you're not sitting directly in front of the speaker. Since door speakers are always angled away from most passengers, this matters a lot. The X 165's tweeter faceplate is shaped specifically to handle this — so the back seat sounds as good as the front.\u003c\/p\u003e\n\u003ch3\u003eQ7: Are these speakers water-resistant?\u003c\/h3\u003e\n\u003cp\u003eThe cone has a water-repellent treatment that handles the humidity and moisture that door speakers deal with every day. They're not waterproof, but they're built to hold up in normal real-world conditions.\u003c\/p\u003e\n\u003ch3\u003eQ8: How hard is the installation?\u003c\/h3\u003e\n\u003cp\u003ePretty straightforward. The DIN basket fits most factory cutouts directly — no drilling or panel modification needed in most cars. Basic tools and about 30–60 minutes per speaker is all it takes.\u003c\/p\u003e\n\u003ch3\u003eQ9: What frequency range do they cover?\u003c\/h3\u003e\n\u003cp\u003e60 Hz to 21,000 Hz — that covers upper bass, all the midrange, and right up to the top of what human ears can hear. It's a genuinely full-range speaker.\u003c\/p\u003e\n\u003ch3\u003eQ10: How do these compare to factory speakers?\u003c\/h3\u003e\n\u003cp\u003eFactory speakers are built to a budget. The Hertz X 165 brings a neodymium tweeter, water-repellent cone, high-flux ferrite magnet, and 220W peak handling — none of which you'll find in OEM speakers. The difference in sound is immediately noticeable.\u003c\/p\u003e\n\u003ch3\u003eQ11: Why does impedance matter?\u003c\/h3\u003e\n\u003cp\u003e4 Ohm is the standard for car audio. It means these speakers will work safely with any car head unit or amplifier without overloading the output. No compatibility issues to worry about.\u003c\/p\u003e\n\u003ch3\u003eQ12: Are they sold as a pair?\u003c\/h3\u003e\n\u003cp\u003ePlease check the product listing details or reach out to us at Dolphin Accessories and we'll confirm exactly what's included in your order.\u003c\/p\u003e","brand":"Dolphin Accessories","offers":[{"title":"Default Title","offer_id":49170220417252,"sku":"Hertz X 165","price":4870.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0655\/9275\/4404\/files\/Hertz_X_165_CO-AXIAL.png?v=1781614325","url":"https:\/\/dolphinaccessories.com\/products\/hertz-x-165-co-axial","provider":"DolphinAccessories ","version":"1.0","type":"link"}
