The principle

Engineered without
a single compromise.

Each RS−9 leaves the workshop only after a 41-step acoustic and mechanical audit conducted by a single technician, whose signature is engraved into the left yoke. No two units leave the line on the same day.

The driver is a hand-tuned 90 mm planar magnetic array, paired with a neodymium magnet system graded N52H. The diaphragm measures 6 µm — thinner than a human hair — suspended on a专利 carbon-fibre frame.

  • Zero resonance

    CNC-milled aluminium yoke, internally damped with closed-cell sorbothane.

  • Pure signal path

    Detachable 6N OCC copper cable, individually shielded, terminated by hand.

  • Long-session comfort

    Lambskin headband, suspended on a magnesium arch. 412 g without cable.

Materiality

The quiet
arithmetic
of metals.

The yoke is milled from a single 7075-T6 aluminium billet over six hours, then hand-polished and anodised in our Vienna facility. The magnet array uses N52H-grade neodymium — the strongest commercially available — arranged in a Halbach configuration to suppress external field leakage by 94%.

The ear pads are filled with memory foam wrapped in full-grain lambskin, tanned with vegetable extracts to preserve acoustic transparency. Each pair is aged for 72 hours before assembly.
