K2 Power ES 165 KX3E 3-way component kit
The K2 Power range is Focal's fourth-generation flagship in-car speaker line. The iconic yellow cone remains the centrepiece, designed for high-fidelity, on-board sound.
Deep, precise bass
The ES 165 KX3E pairs two 6 1/2" (165mm) woofers with two 4" midranges to cover a wide frequency spectrum, from deep bass through to a rich, dynamic midrange. Both use Focal's K2 aramid fibre sandwich cone — an ultralight foam core between a layer of aramid fibre and a layer of fibreglass — combining rigidity, lightness and damping for precise, powerful sound.
The kit also includes bi-amplifiable audiophile crossovers and angled tweeter brackets for flexible installation.
FRAK tweeter
The ES 165 KX3E is equipped with Focal's M-profile FRAK tweeter, constructed from aluminium and magnesium. The design lowers the usable frequency range, improves damping and, thanks to its light weight, extends high-treble performance. The result is crystal-clear, ultra-realistic treble reproduction.
More linearity and precision
The progressive spider on the K2 Power woofer uses a progressive section to handle bass impact accurately, increasing linearity, precision and dynamics.
Increased SPL
The Radial VC cooling system vents hot air from the voice coil through 6 holes towards the base of the motor. This keeps coil temperature in check, reduces heat compression and improves reliability, contributing to higher dynamics and greater output.

About the Focal ES 165 KX3E
From our tech experts at CEN
Focal K2 Power Series 6.5 inch three-way component speakers, with a separate tweeter, midrange and woofer.
Who it suits
Drivers building a proper front stage and happy for tweeters to be mounted separately, which usually means a professional fit. K2 Power is Focal’s long-running aramid-fibre range, the one enthusiasts recognise by the yellow cone.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker, and Focal drivers repay an amplifier. 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: How many drivers are in the ES 165 KX3E kit?
A: The kit contains two woofers, two midrange drivers and two FRAK tweeters, plus crossovers, grilles, speed clips, screws and an owner's manual.
Q: How much power can the ES 165 KX3E handle?
A: The woofers are rated at 120W RMS (240W maximum) and the midranges at 50W RMS (100W maximum).
Q: Can the ES 165 KX3E be bi-amplified?
A: Yes. The kit uses bi-amplifiable audiophile crossovers.
