Schematic planar magnetic assembly, annotated with the Audeze MM-520’s published materials. Not to scale.

Engineering notes

  • SLAM (Symmetric Linear Acoustic Modulator, patent pending) added to manage air pressure in the earcup for low-frequency response
  • 90 mm planar drivers with Ultra-Thin Uniforce diaphragms, Fluxor N50 magnet array and Fazor phase management
  • Upgraded memory foam earpads with magnetic attachment for replacement
  • Voicing refined with mix engineer Manny Marroquin; 18 ohm and 102 dB/mW for console and interface use

Design language

Workmanlike and built to last: a spring steel band with leather, machined yoke rods and magnetic pads you can swap in seconds.
