  • Grade-2 PRIME are not offered and only used within Zu loudspeaker systems.
  • Grade-2 (≈20% of all matched sets). Pairs receiving this grade have nearly identical tone prints and dynamic behavior. Average nominal SPL difference between pair is zero.
  • Grade-1 (≈30% of all matched sets). Above average matching having nearly identical tone prints and dynamic behavior but allow for a few subtle divergence. Average nominal SPL difference between pair is 1/8dB.
  • Standard Grade (≈45% of all matched sets). "Standard" is still a pretty tightly matched pair but allows for a few points of divergence within the tone print matching process. Average nominal SPL difference between pairs is a very low 1/4dB.
  • ≈3% of the APT50 drivers do not pair to our Standard Grade level and are sold as singles.
  • ≈2% of the APT50 drivers do not pass our pass/fail tests and are destroyed and recycled.
