K2 SANDWICH MEMBRANE

Purity and precision of sound

The diaphragm, the key component of a loudspeaker, is at the heart of our acoustic engineers’ research. Shape and materials are essential for high-fidelity reproduction. In 1986, our teams unveiled an aramid fibre sandwich membrane, recognizable by its unique yellow color. It has been extensively renewed over the years, while retaining the characteristics that made it such a success. Today, it consists of an ultra-light foam core sandwiched between a layer of aramid fibre and a layer of glass fibre. It combines the three key factors of a loudspeaker membrane: rigidity, lightness and damping, for a precise, dynamic and uncolored sound.

“M” PROFILE

For ever greater impact

If the material of a membrane is essential, so is its shape. Focal engineers worked on an “M” profile for the glass fibre “W” membrane. This “M” profile is the fruit of many years of research and our expertise in membrane geometries. Produced in a single piece (without a core cover), it achieves, among other things, a significant reduction in harmonic distortion, better sound dispersion and optimal power handling. A major Focal innovation that can be found on many products.

TMD SUSPENSION

Stabilized surround, eliminates vibrations

While our engineers are experts in the development of exclusive diaphragms, they also innovate in all the components that make up the loudspeakers, such as the surround that connects the diaphragm to the frame, the performance of which must be mastered. Introduced in 2015, Tuned Mass Damper (TMD) technology with harmonic damping consists of the addition of finely positioned toroidal weights to stabilize the surround for even greater sonic neutrality. This technology enhances the midrange and the erratic behavior of the surround between 1 kHz and 2 kHz.

Focal 3 KM | 3″ (80 mm) Mid-Range Driver – K2 Power M Series

Performance Meets Precision in Compact Form

The 3 KM is a specialised 3-inch (80 mm) mid-range driver built for serious car audio systems that demand clarity and fidelity in tight installation spaces. As part of the K2 Power M series, it brings Focal’s premium acoustic technologies into a compact format

Why Use It?

If you’re building a custom high-fidelity car audio system, the 3 KM allows precise mid-range reproduction with high accuracy. Its compact size makes it suitable for limited spaces while maintaining premium acoustic performance. The use of the “M” profile cone ensures better dispersion and reduced installation depth — ideal for demanding installs.

Installation & System Considerations

  • Because this is a dedicated mid-range driver, you’ll need appropriate crossover filters (often active crossovers) to ensure proper integration with tweeters and woofers.

  • Its compact depth (~27 mm) allows for flush or near-flush mounting in constrained spaces.

  • Should be paired with other components from the K2 Power M line to maintain tonal match and performance (e.g., 6.5 KM woofer, FRAK tweeter).

  • Ensure your amplifier and system power levels align with the RMS/peak specs to avoid under- or over-driving.

Summary

The Focal 3 KM mid-range driver brings audiophile-grade mid-range clarity into a compact form, leveraging top-tier technologies like the K2 sandwich cone, TMD surround, and M-profile design. If you’re seeking to elevate your car audio build with precision and performance — this is a strong choice.
