The Princess of Clarity

Named after the Cyrillic letter “Ф” – pronounced Ef – the AC-4Ф Silver stands as the queen of the Voxativ driver family. For those with a love of chess, it symbolizes elegance and strategic perfection. For those with a mind for physics, “Ф” speaks of magnetic flux and the golden ratio – a union of science and art.

This is our highest-resolution driver, crafted for those who seek nothing less than pure sonic truth. Its wooden cone and foam surround offer a delicate balance of warmth, speed, and transparency. Whether in open baffle designs or refined back-loaded horns like the Voxativ Ampeggio or 9.87 system, the AC-4Ф Silver reveals the soul of music—intimate, open, and breathtakingly alive.
