Made in France in our workshops, the TNF aluminum/magnesium inverted dome tweeter delivers smooth, clear treble. The surround that connects the dome to its support uses Poron, a shape-memory material. This surround is directly derived from Focal's famous Beryllium tweeter, and reduces distortion by a factor of three between 2000 Hz and 3000 Hz, the most sensitive zone for the ear. In addition, a waveguide has been developed to perfect spatialization and further improve the inverted dome's very low directionality. In the horizontal plane, the frequency response is within +/- 0.5 dB. This performance guarantees an incredibly stable soundstage.

As the key component of a loudspeaker, the membrane is at the heart of our acoustic engineers' research. After more than five years of research and development, in 2013 Focal unveiled an exclusive membrane made from flax. Patented, this Flax cone is a sandwich made of very high quality French flax fibre placed between two thin sheets of glass fibre. It satisfies all the criteria of a high-fidelity membrane: lightness to offer good dynamics, rigidity to hold the bass and damping to deliver a neutral, natural, uncolored sound. It is an emblematic Focal innovation in many hi-fi products.
