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.

PROGRESSIVE SPIDER

For exceptional dynamics

At the rear of the diaphragm is the spider, which holds the lower part of the cone in place. By working on this essential element of the loudspeaker, and in particular by developing a spider with a progressive profile, our engineers have achieved better damping of the sandwich cone’s movements, greatly enhancing the linearity, precision and dynamics of the sound.

SUB 5 KM | 5 ¾″ (145 mm) Subwoofer – Focal K2 Power M Series

Compact Power. Unmatched Precision.

The Focal 5 KM 5 ¾″ (145 mm) subwoofer brings unrivalled energy, impact, and definition to compact in-car audio systems. Part of the elite K2 Power M Series, it’s engineered for enthusiasts who demand audiophile-grade bass performance in tight spaces — without compromise.

Designed, developed, and crafted in France, the 5 KM delivers pure Focal DNA: clarity, dynamics, and control. Its exclusive aramid fibre K2 sandwich cone is paired with an ‘M’-profile geometry for a broader frequency range, wider dispersion, and reduced depth — creating a driver that is both ultra-compact and ferociously capable.

K2 Cone Technology – High Fidelity Reinforced

The legendary K2 cone is the heart of Focal’s performance philosophy. Its aramid fibre construction delivers the perfect balance of rigidity, lightness, and damping, ensuring deep, controlled bass and faithful sound reproduction.

Enhanced with Focal’s exclusive ‘M’-profile, the 5 KM produces smoother response, better soundstage integration, and reduced resonance for bass that’s tight, accurate, and emotionally charged.

Patented TMD® Surround – Zero Distortion Bass

Borrowed from Focal’s flagship Sopra hi-fi range, the TMD (Tuned Mass Damper) surround controls resonance and cone stability for exceptional clarity and low-frequency precision. It suppresses harmonic distortion even at high output, delivering bass that remains clean and musical no matter the volume.

Progressive Spider – Dynamic Damping and Linear Movement

Focal’s progressive profile spider ensures linear motion and tight control of the cone’s travel, enhancing the system’s responsiveness and impact. This technology guarantees faithful dynamic performance with no compression or flutter — only deep, powerful bass with surgical accuracy.

Compact Form. Limitless Potential.

The 5 KM’s active-ready design and compact footprint make it the perfect foundation for custom or factory-integration systems. Its small depth and lightweight chassis enable seamless installation in tight spaces without sacrificing output or fidelity.

For the ultimate Focal experience, pair the 5 KM with the 3 KM midrange and FRAK tweeter to create a perfectly balanced 3-way K2 Power M system.

The K2 Legacy Continues

Compact in form but immense in performance, the Focal 5 KM delivers the signature energy and musicality of the K2 Power M range — with the added benefit of ultra-flexible installation. Built for those who demand precision and passion in equal measure, this is bass redefined for the modern audiophile.

Focal 5 KM – Compact Design. Colossal Performance.
