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.

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.

SUB 25 KXE | 10″ Subwoofer – Focal K2 Power Series

 

Unleash the Power of Precision Bass

The Focal SUB 25 KXE defines the next generation of high-performance car audio. Built within Focal’s fourth-generation K2 Power Series, this 10″ (250 mm) subwoofer delivers pure impact, depth, and control with the unmistakable K2 sound signature.

Designed, developed, and hand-crafted in France, the SUB 25 KXE combines a dual voice-coil motor, aramid-fibre K2 cone, and aerodynamic aluminium frame for powerful, articulate bass reproduction that retains musical precision even at high output levels.

K2 Cone – Dynamic Strength, Refined Detail

The heart of the SUB 25 KXE is its aramid-fibre K2 sandwich cone, offering the perfect balance of rigidity, low mass, and internal damping. The result is tight, controlled bass with exceptional transient response, delivering every low-frequency nuance with realism and intensity.

This precision construction reproduces your music’s energy and emotion — fast, deep, and distortion-free.

Engineered for Maximum Output

A dual voice-coil motor unit provides greater flexibility in system design and increased linear power handling. Combined with Focal’s coil ventilation system, the SUB 25 KXE maintains peak performance under extreme load — clean, powerful bass session after session.

The progressive-profile spider ensures full control of cone movement, improving linearity and dynamic expression, while the special rubber surround enhances excursion and long-term durability.

Built for Performance and Longevity

Every component of the SUB 25 KXE is built to withstand the rigours of high-energy audio environments:
• Rigid aluminium chassis – non-magnetic and resonance-free
• Push terminal block – secure, quick-fit wiring
• Engraved serial number – authenticity and traceability
• Optimised airflow design – heat management for sustained SPL performance
