【FOCAL ES 165 K2S｜K2 Power 2-Way Speakers Enjoyed with a Slim Design】

I want the sound from my factory speakers to be a bit more powerful. I want to feel the fine details of vocals and instruments much closer. That’s what the FOCAL ES 165 K2S is for.

It’s a separate 2-way speaker that balances the kind of power and finesse you expect from the K2 Power series, yet its mounting depth is only 58 mm. This slim design also takes into account the door’s internal space—something you often worry about when replacing speakers.

A Tight, Refined Sound—Uniquely from the K2 Cone

The woofer uses the yellow K2 sandwich cone made of aramid fiber. The light yet rigid cone is paired with a TMD suspension that suppresses unwanted vibrations.

Rather than simply playing bass louder, this design makes the contours of the bass and kick drums easier to hear, giving the entire track a stronger core. You’ll also find it easier to perceive the thickness of vocals and the attack of instruments like guitars and pianos.

The 25 mm aramid dome tweeter features an M-shaped structure and TMD. While it clearly draws out high-frequency information and imaging, it’s designed to stay naturally listenable—less likely to become overly stimulating even during long listening sessions.

Even with a Slim Form, Sound Changes with Installation Method

With the ES 165 K2S, the impression isn’t determined only by the speaker itself, but also by how the door side is prepared and by the installation condition. It’s important to consider things tailored to your vehicle—from choosing the baffle, treating the inside of the door, and setting the tweeter’s direction, to the combination with the factory audio or an amplifier.

Also, because it is a 2-ohm specification, it’s safer to check the compatibility with your factory audio or existing amplifier on a vehicle-by-vehicle basis. This is an attractive model for anyone who wants to choose slim speakers to fit the available space, but you’ll want to select it by considering how well it matches your entire system—not just by swapping speakers.

At LOGON, we organize together—while confirming your vehicle model, factory system, the music you usually listen to, and how you use volume—how much work needs to be done to reach a satisfaction level. If you’re going to replace your speakers, wouldn’t you want a finish where, after installation, you think, “Let me listen to this track again”?
