Three corrugated aluminium ribbons per side, each tuned to a slightly different resonance, with magnets only around the perimeter so nothing sits in the acoustic path. It runs from a ribbon interface or a direct-drive amplifier, and $7,510 buys the headphone alone.

Engineering notes

  • R3 triple true-ribbon array: three corrugated pure aluminum foil ribbons, 25.2 cm2 combined area, +/-4 mm excursion
  • Complementary segment tuning: each ribbon tuned to a slightly different resonance, plus Viscodamp 'Silent Metal' viscosity damping
  • Perimeter-only magnets leave the acoustic path unobstructed
  • 0.057 ohm load, driven through an RCDI current-drive interface or direct-drive ribbon amplifier via female 4-pin XLR

Design language

American walnut veneer with a hard wax finish, gold-plated etched steel grilles and a TiAlN-coated spring band.
