Hertz CPK 165 Review: Cento Pro Components with a 29 mm Tweeter, Compared with the CK 165
Updated: Oct 7
The Hertz CPK 165 is the 6.5-inch (165 mm) two-way component set in Hertz's Cento Pro line: CP 165 woofers, CP 25 tweeters with 29 mm domes, CPCX 2 crossovers and grilles, rated at 105 W continuous and 315 W peak with 92.5 dB sensitivity. Its Indian MRP is ₹29,990, the highest of the Cento and Cento Pro speakers we sell and well below the Mille Pro MPK 165.3. It suits owners who want a step beyond the Cento CK 165 for an amplified front stage. See today's price on our Hertz CPK 165 product page.
Quick summary
A larger 29 mm Tetolon tweeter with a 25 mm voice coil, and a crossover at 2.8 kHz with a three-step tweeter level (-2, 0 or +2 dB).
A pressed-paper woofer on a butyl rubber surround with a pure copper voice coil, rated down to 45 Hz.
It handles more power than the Cento sets (105 W continuous) with essentially the same sensitivity.

Cento Pro vs Cento: CPK 165 against CK 165
The obvious question is whether the Pro set is worth ₹5,000 more than the Cento CK 165. Here is how Hertz's own figures compare.
Specification | CPK 165 (Cento Pro) | CK 165 (Cento) |
|---|---|---|
Woofer cone | Pressed paper, butyl surround | SPP-M, semi-pressed paper with mica; surround not stated |
Woofer voice coil | 25 mm, described as pure copper; former not stated | 25 mm, aluminium former; wire not stated |
Tweeter | 29 mm dome, 25 mm voice coil | 26 mm dome, 20 mm voice coil |
Crossover | 2.8 kHz, 12 dB/octave | 2.5 kHz, 12 dB/octave |
Tweeter level | -2 / 0 / +2 dB | 0 / +3 dB |
Power handling | 105 W continuous, 315 W peak | 95 W continuous, 285 W peak |
Sensitivity | 92.5 dB | 92 dB |
Frequency response | 45 Hz – 22.5 kHz | 55 Hz – 22.5 kHz |
India MRP | ₹29,990 | ₹24,990 |
Both include grilles, and the sensitivity difference is too small to matter. What the extra money buys is a bigger tweeter with a larger voice coil, a deeper published low end, more power handling and a tweeter adjustment that can cut as well as boost. Our Hertz CK 165 review covers the Cento set, including how it differs from the CK 165 L.
Inside the CP 165 and CP 25
The CP 165 woofer's pressed-paper cone has an FEM-optimised shape for stiffness without extra mass, and it rides on a butyl rubber surround. Its pure copper voice coil is sized for high excursion, and Hertz puts its resonance at 60 Hz; our listing says that tuning is meant to give punch at medium and low power.
The CP 25 tweeter is a 29 mm soft Tetolon dome with a 25 mm voice coil and a neodymium magnet. A larger voice coil generally handles heat better. The three-position level switch is a practical touch for cars: use +2 dB when the tweeters sit low or off-axis, and -2 dB when they fire straight at you off a raked windscreen.
Factory head unit or amplifier?
At 92.5 dB, the CPK 165 will play from a factory or aftermarket head unit, but its extra power handling only matters with an amplifier. On head-unit power, that part of the gap to the cheaper Cento sets goes unused.
An amplifier giving 70 to 75 W per channel suits the 105 W continuous rating. The Zapco ST-5B offers four 70 W channels plus a 250 W subwoofer channel, and the JL Audio JD700/5 pairs four 75 W channels with a sub channel and accepts speaker-level signals from a factory head unit. Our guide on when a car needs an amplifier explains the basics.
What owners and reviewers say about the Hertz CPK 165
When we checked in October 2026, we could not read any owner reviews of the CPK 165. A DIYMobileAudio thread titled Opinions on Hertz CPK 165 Pro exists, but the page was blocked to us, so we can't say what its posters concluded. The Crutchfield and ABT review sections did not load, and we found no Indian owner threads.
BestCarAudio's 2019 Cento speakers spotlight, a sponsored post, says that stepping up to the CPK 165 brings more power handling and more excursion than the Cento sets, and adds that separate high-pass and low-pass crossover modules improve output and make installation easier; Hertz's own CPK 165 page describes the CPCX 2 crossover without mentioning separate modules, so we have not relied on that. Treat it as promotional. If you own a CPK 165, we would like to hear how it sounds in your car.
Who should buy it, and who shouldn't
Buy the CPK 165 if you are building an amplified front stage, want the bigger tweeter and the flexibility of a cut-or-boost level switch, and can mount tweeters high. It has the highest power rating and the deepest published low end of the Cento and Cento Pro component sets we sell, though only by 5 W and 5 Hz over the CK 165 L.
Look elsewhere if you are staying on head-unit power, where the cheaper CK 165 or CK 165 L makes more sense, or if you want Hertz's next tier: the Mille Pro MPK 165.3 (₹49,990 MRP) is rated down to 40 Hz and comes with mounting accessories.
Installation notes for Indian cars
Measure woofer depth and window-glass clearance before ordering, since Hertz doesn't publish the CP 165's mounting depth, and expect an adapter bracket in many cars. Damp the door skin while it is open; a resonant door wastes the woofer's midbass and rattles on broken roads. Our guide to applying sound damping explains how.
The CP 25 has a larger dome than the C 26 in the CK 165 and weighs more (0.07 kg against 0.03 kg), so check that a factory tweeter location can take it before planning a stealth install; custom A-pillar or sail mounts are the alternative. Mount the CPCX 2 crossovers somewhere dry and accessible, so the level switch can be changed after tuning. VA3 Car Studio offers professional installation in Ghaziabad.
Price and where to buy
The CPK 165 has an MRP of ₹29,990 in our listing, which includes woofers, tweeters, CPCX 2 crossovers and woofer grilles. Check today's price on the CPK 165 product page. Every set we sell is a genuine Hertz product.
The bottom line
This is the Cento Pro step: a bigger tweeter, a woofer rated deeper and for more power, and a more flexible level switch than the Cento CK 165, for ₹5,000 more. It makes most sense with an amplifier and well-placed tweeters, and less on head-unit power. With no owner reviews to report, you are buying on Hertz's specifications.
Hertz CPK 165 FAQ
What does the Hertz CPK 165 add over the CK 165?
Hertz gives the CPK 165 a 29 mm tweeter with a 25 mm voice coil (against 26 mm and 20 mm), a 45 Hz lower limit (against 55 Hz), 105 W continuous (against 95 W) and a -2, 0 or +2 dB tweeter level switch. Sensitivity is almost identical, at 92.5 against 92 dB.
Does the CPK 165 need an amplifier?
It plays from a head unit, but its extra power handling only pays off with an amplifier. Around 70 to 75 W per channel into 4 ohms suits its 105 W continuous rating.
Which tweeter level setting should I use?
Start at 0 dB. Use +2 dB if the tweeters are mounted low or aimed away from you, and -2 dB if they fire straight at you and sound bright, which is common off a steeply raked windscreen.
