Hertz CPX 165 Review: The Cento Pro Coaxial, and What It Adds over the CX 165
Updated: Oct 7
The Hertz CPX 165 is a 6.5-inch (165 mm) two-way coaxial from Hertz's Cento Pro line, rated at 95 W continuous and 285 W peak, with 92 dB sensitivity and a published response down to 45 Hz. Its Indian MRP is ₹19,990, between the Cento CX 165 coaxial and the Cento Pro CPK 165 component set. Our listing describes it as the choice for cars where a separate two-way component kit can't be installed, so it suits owners who want more than a basic coaxial but must keep the factory speaker layout. See today's price on our Hertz CPX 165 product page.
Quick summary
Pressed-paper woofer on a butyl rubber surround, a 24 mm Tetolon tweeter with a 20 mm voice coil, and a vented motor Hertz calls the Radial Venting System.
Over the Cento CX 165 it adds power handling (95 W against 70 W continuous) and a deeper rated low end (45 Hz against 55 Hz).
Hertz prints two depth dimensions for it, 84.5 mm and 65.5 mm, without saying which is the mounting depth, so check your doors first.

Figures come from Hertz's official CPX 165 page, with the surround material, MRP and grille status from our listing, which notes that grilles are not included. Hertz prints depth as two unlabelled dimensions, C at 84.5 mm and D at 65.5 mm, and does not say which is the mounting depth; we show the larger figure because it is the safer one to plan around.
What is inside the CPX 165
The woofer uses a pressed-paper cone on a butyl rubber surround, which our listing says is chosen for extended low-frequency reproduction, in line with the deeper 45 Hz figure. Behind it, the Radial Venting System puts eight holes in the base of the motor, which Hertz says cool the voice coil and help give a natural midrange. The woofer magnet is damped and rubber-coated, a detail our listing says comes from Hertz's Mille range.
The tweeter is a 24 mm Tetolon fibre dome with a neodymium magnet and a 20 mm voice coil, larger than the 13 mm coil in the CX 165's tweeter. Hertz lists a 4 kHz, 6 dB/octave crossover, and our listing describes the tweeter as designed for wide off-axis dispersion, which helps a coaxial that sits low in a door.
Factory head unit or amplifier?
At 92 dB, the CPX 165 will work on a factory or aftermarket head unit, but that isn't where it shines. Its advantages over the cheaper CX 165 are power handling and a lower rated bass limit, and the extra power handling only matters with an amplifier. On head-unit power, the slightly more sensitive CX 165 is the more sensible buy.
With an amplifier, aim for no more than the 95 W continuous rating per channel. The Zapco ST-2B provides 65 W per channel into 4 Ω and accepts OEM speaker-level input, so it can sit behind a factory touchscreen. The Zapco ST-5B runs four 70 W channels plus a 250 W subwoofer channel for a complete system. Our guide on when a car needs an amplifier covers the basics.
What owners and reviewers say about the Hertz CPX 165
When we checked in October 2026, we could not read any owner reviews of the CPX 165. A Harley Davidson Forums thread is titled for the CPX 165 PRO, but the page was blocked to us, so we can't say what it covers or report what its posters said. Crutchfield's review section did not load, Sonic Electronix blocked access, and we found no Indian owner threads.
That leaves Hertz's own description, which is promotional by nature. We won't invent a verdict. If you have fitted a pair, we would like to hear how they perform in your car.
CPX 165 vs CX 165, CPK 165 and MPX 165.3
Against the Cento Hertz CX 165 (₹12,990 MRP), the CPX 165 handles 95 W continuous against 70 W, reaches 45 Hz against 55 Hz, and swaps the mica-filled SPP-M cone for pressed paper on butyl. The CX 165 is 1 dB more sensitive (93 dB) and lighter, and Hertz prints 62.5 mm for both of its depth dimensions, against 84.5 mm and 65.5 mm for the CPX 165. Hertz lists a rotary, aimable tweeter mount (RHFC) for the CX 165 but not for the CPX 165.
The Cento Pro CPK 165 (₹29,990 MRP) is the component version, with a 29 mm tweeter, a CPCX 2 crossover and 105 W continuous; choose it if your car can take tweeters higher up. One step above, the Mille Pro MPX 165.3 coaxial (₹24,990 MRP) uses a 36 mm woofer voice coil and a pressed pulp cone with cotton fibres, rated at 100 W continuous.
Who should buy it, and who shouldn't
Buy the CPX 165 if your car can't take a component set, you are adding an amplifier, and your doors have the depth for it. It gives you more power handling and a deeper rated low end than the CX 165 without changing the factory speaker layout.
Look elsewhere if you are staying on head-unit power or have shallow doors, where the CX 165, at 62.5 mm, is the safer bet, or if you can mount tweeters high, where a component set images better.
Installation notes for Indian cars
Depth is the first check. Hertz prints 84.5 mm and 65.5 mm for the CPX 165 without saying which is the mounting depth, against 62.5 mm for the CX 165, so measure from the mounting surface to the window glass at its lowest travel and plan around the larger figure before ordering. A spacer ring can buy clearance, and many cars need an adapter bracket anyway; we can confirm what yours needs.
Leave air around the back of the motor, since the venting holes are there for cooling, and don't press damping material or foam against them. Do damp the door skin itself, though: a solid door gives a 6.5-inch woofer real midbass and stops rattles on broken roads. Our guide to applying sound damping explains how. VA3 Car Studio offers professional installation in Ghaziabad.
Price and where to buy
The CPX 165 has an MRP of ₹19,990 in our listing. Check today's price on the CPX 165 product page. Grilles are not included, and every speaker we sell is a genuine Hertz product.
The bottom line
This is a coaxial for people who would rather have a component set but can't fit one: more power handling and a deeper rated low end than the Cento CX 165, a vented motor and a larger tweeter voice coil. It is deeper and slightly less sensitive, so it pays off most with an amplifier and a door that has room. With no owner reviews to report, you are buying on Hertz's specifications.
Hertz CPX 165 FAQ
Is the Hertz CPX 165 worth it over the CX 165?
It depends on your setup. With an amplifier, Hertz rates it at 95 W continuous against 70 W and down to 45 Hz against 55 Hz. On head-unit power, the CX 165 is 1 dB more sensitive and cheaper.
Will the CPX 165 fit my door?
Hertz prints depth dimensions of 84.5 mm and 65.5 mm without saying which is the mounting depth, so plan around the larger figure. Measure from the mounting surface to the window glass at its lowest point; a spacer ring or adapter bracket often solves it, and we can check your car.
Does the CPX 165 need an amplifier?
It will play from a head unit, since it is rated at 92 dB, but its extra power handling only matters with an amplifier. One giving no more than its 95 W continuous rating per channel, such as the Zapco ST-2B at 65 W into 4 ohms, suits it.
