K2 SIGNATURE
A Focal innovation, the K2 diaphragm is supported by a sturdy, highly reliable rubber surround, whose exclusive profile has been optimized to offer very high travel. It is the source of high-quality sound reproduction.
Combine the pleasure of listening with the pleasure of driving
ROBUSTESSE
Rigid, non-magnetic and specially designed for K2 Power, the aluminum frame improves coil excursion and enables the subwoofer to deliver a taut, punchy bass. At Focal, every detail counts.
POWER
Thanks to a Radial VC ventilation system, the coil temperature is better controlled for even greater reliability. The loudspeakers become more dynamic, generating powerful sound.
Technologies
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.
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.
