Focal K2 Power ES 165 K2S 6.5 Inch 16.5cm Slim 2 Way Component Speakers 70w Pair
Couldn't Load Pickup availability
The Focal ES 165 K2S is a slim 6.5 inch (165mm) 2-way component speaker kit from the Focal K2 Power fourth-generation range. It features yellow aramid fibre K2 sandwich cone woofers and aramid fibre TKME inverted dome tweeters, rated at 70W RMS with a shallow 58mm mounting depth.
Note: this kit has a 2 ohm nominal impedance — check your amplifier is stable at 2 ohms before connecting.
Key specifications
- Type: 2-way component kit
- Woofer size: 6 1/2" (165mm)
- Woofer depth: 2 1/4" (58mm)
- Power handling: 70W RMS, 140W maximum
- Sensitivity: 88dB (2.83V/1m)
- Frequency response: 60Hz – 22kHz
- Impedance: 2 ohms
- Crossover: 6–12/12dB at 3kHz, bi-amplifiable
Compact and dynamic
The ES 165 K2S consists of two 6 1/2" (165mm) woofers with a shallow depth of 2 1/4" (58mm), making them suitable for door locations where a full-depth driver will not fit. Despite the slim profile, the kit delivers strong performance for its size. If you need a 6.5" component kit without the slim-depth requirement, Focal also offer the Focal 165 AS Access Series 2-way speakers and the Focal 165 AS3 Access Series 3-way speakers.
Like all K2 Power kits, the ES 165 K2S uses the iconic aramid fibre K2 sandwich cone — yellow, rigid, lightweight and well-damped. The two 'M'-shaped inverted dome TKME tweeters, also made of aramid fibre, are paired with bi-amplifiable audiophile crossovers for precise high-frequency control. Aluminium grilles are included.
K2 sandwich cone
The aramid fibre cone features an ultralight foam core sandwiched between a layer of aramid fibre and a layer of fibreglass. This construction combines rigidity, lightness and damping for precise, dynamic sound.
TKME tweeter
The 'M'-profile TKME tweeter extends frequency response to 22kHz with reduced distortion. A 'push-pull' motor based on IAL2 technology achieves very low resonance frequencies for balanced harmonic reproduction.
More linearity and precision
The progressive spider uses a progressive section to reproduce bass impact accurately and improve linearity, precision and dynamics.
Increased SPL
The Radial VC cooling system expels hot air from the voice coil through 6 holes towards the bottom of the motor. This controls coil temperature, limits heat compression, improves reliability and increases dynamics.

About the Focal ES 165 K2S
From our tech experts at CEN
Focal K2 Power Series 6.5 inch component speakers, with separate tweeters that can be mounted where you will actually hear them.
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. The slim version suits doors where mounting depth is tight.
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: What impedance is the ES 165 K2S?
A: The ES 165 K2S has a nominal impedance of 2 ohms. Make sure your amplifier or head unit can run a 2 ohm load.
Q: How deep are the ES 165 K2S woofers?
A: The slim woofers have a depth of 2 1/4 inches (58mm), which makes them easier to fit in shallow doors.
Q: What's in the box with the ES 165 K2S?
A: The kit includes the woofers, tweeters, crossovers, grilles, speed clips, screws and an owner's manual.
