The HELIX PF K165.2 is a 6.5 inch (165 mm) 2-way component speaker set from the Pure F-Series, rated at 60 W RMS / 120 W max, with 3 ohm impedance for increased output from your amplifier.

This set pairs a 20 mm silk dome tweeter and a 6.5 inch (165 mm) woofer with a two-part Flex-Crossover, so the tweeter can be mounted in the A-pillar or dash and the woofer in the door. Prefer a single-unit speaker? See the HELIX PF C165.2 coaxial. Other sizes in this set: PF K100.2 and PF K130.2.

    • Two-stage tweeter level adjustment with integrated tweeter protection

Easiest integration at its best

The PF K165.2 is designed for straightforward installation. The low-profile woofer accommodates the limited space in modern vehicles, and the Flex-Crossover simplifies wiring when the tweeter and woofer are in separate locations. The compact tweeter fits via an innovative bayonet lock and includes multiple mounting pods for flexible positioning.

Maximum flexibility – the "Flex-Crossover"

The two-part Flex-Crossover is space-saving by design and ideal when the tweeter sits in the A-pillar and the woofer in the door. The tweeter crossover includes a two-stage level adjustment so you can tune the sound to suit both your listening preference and your installation.

Cool design – noble materials

The Space Line styling of the woofer cone is a result of the materials used rather than aesthetics alone. Carbon fibres embedded in the polypropylene cone improve midrange reproduction, while the coated silk dome tweeter delivers open, airy highs.

    About the Helix F622621

    From our tech experts at CEN

    6.5 inch component speakers, with separate tweeters that can be mounted higher where you will actually hear them, rated at 60w RMS.

    Who it suits

    Drivers building a proper front stage. Helix is a brand people choose when they care about staging and detail rather than volume, and these reward an amplifier and a processor.

    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 and tweeter placement change the result as much as the speaker does. Installation and tuning are 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: What size is the HELIX PF K165.2 woofer?

    A: The woofer is 6.5 inch (165 mm), with an installation diameter of 142 mm and an installation depth of 61 mm. The tweeter is a 0.75 inch (20 mm) silk dome.

    Q: What impedance are the PF K165.2 speakers?

    A: They are 3 ohm speakers. HELIX uses 3 ohm technology in the PURE F-Series to get more power from the amplifier than a typical 4 ohm speaker. Power handling is 60 W RMS and 120 W max.

    Q: Can the PF K165.2 tweeters be mounted separately from the woofers?

    A: Yes. The Flex-Crossover splits into two parts, so the tweeter section can sit near an A-pillar tweeter and the woofer section in the door. Six tweeter mounting accessories are included, covering flush, angled and OE mounting positions.
