The Aluminum-Magnesium tweeter

Since main monitors are frequently soffit-mounted, these require external electronics for this application. Focal engineers have therefore developed an amplification system combining a class H with a current mode. By controlling the current (instead of the voltage), it is possible to directly control the force submitted to the membrane and eliminate any unwanted artefacts. Combined with analogue filtering and exceptional drivers, this amplification achieves the lowest THD ever measured in an anechoic chamber.

Patented by Focal, the pure beryllium ‘M’ profile tweeter combines rigidity, lightness and damping for exceptional high-frequency reproduction. The ‘M’ membrane is the result of many years of research and expertise. Made in a single piece, it improves sound dispersion, reduces distortion and ensures optimum power handling.

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.
