The Summit of Sound

Designated by the Cyrillic letter “Ф” – pronounced Ef – the AC-4Ф Gold marks the pinnacle of the Voxativ driver lineage. In the world of chess, this symbol represents the queen – elegant, powerful, and irreplaceable. In physics, “Ф” signifies magnetic flux and the golden ratio – both embodied in this extraordinary transducer.

This ultimate version unites Voxativ’s patented Endless Gap® technology with an exceptionally supple goat leather surround and a refined wooden cone of exquisite responsiveness. The magnet system is crafted from a specially selected, flux-optimized steel alloy – engineered to reveal every nuance of sound, from the softest whisper to the most commanding crescendo.

With its unmatched resolution and musicality, the AC-4Ф Gold is built for the most sophisticated open baffle designs and high-art backloaded horns such as our Ampeggio and 9.88 system. It is more than just a loudspeaker driver – it is our sonic statement.
