Uno speakers: where the sound experience begins
The K 165 features a 24 mm (0.9") neodymium tweeter with PEI dome for accurate high-frequency reproduction in a compact size. The annular acoustic lens is optimised for off-axis performance, producing a precise stereo image.
The 6.5" woofers use a pressed-paper V-cone with foam surround for high SPL and solid bass. A 25 mm (1") voice coil driven by a high-flux density ferrite magnet delivers dynamic, undistorted power handling. The 6 dB/oct crossover is integrated on the tweeter wiring for a straightforward OEM upgrade.

About the Hertz K 165
From our tech experts at CEN
Hertz Uno series 6.5 inch component set, with separate tweeters that can be mounted higher where you will actually hear them, rated at 75w RMS.
Who it suits
Drivers who want a proper front stage and are happy for tweeters to be mounted separately, which usually means a professional fit. Component sets are where a car system starts sounding like a hi-fi rather than louder.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker itself, and an amplifier will get far more out of these than a head unit can. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Does the Hertz Uno K 165 have a separate crossover?
A: No separate crossover box is needed. A 6 dB/oct crossover is integrated on the tweeter wiring, which makes it an easy upgrade over factory speakers.
Q: How can the K 165 tweeters be mounted?
A: The T 24 tweeters can be flush mounted using the supplied trim rings and clamps, or surface mounted using the angled housings, which are included.
Q: What's in the box with the Hertz Uno K 165?
A: Two V 165 woofers, two T 24 tweeters, tweeter flush mount trim rings and clamps, angled surface mount housings, tweeter grilles (installed), screws, speed clips, round adhesive foam pads and an owner's manual, with a mounting template on the box.
