64Audio U18t vs U12t

U18t:

18 Drivers

10hz – 20kHz Frequency Response

9Ω Impedance @1kHz

Integrated 4-way Passive Crossover

U12t:

12 Drivers

10hz – 20kHz Frequency Response

12.6 +1/-2 Ω Impedance from 10hz – 20kHz

Integrated 4-way Passive Crossover

Our Analysis:

  • The U18t delivers supreme detail, resolution, and accuracy for a truly reference-grade sound monitoring.
  • The U12t is meant as an all-rounder, focusing on flat sound signature and precision for reference-level IEM listening.

64Audio U18t vs U18s

U18t:

18 Drivers

10hz – 20kHz Frequency Response

9Ω Impedance @1kHz

Integrated 4-way Passive Crossover

U18s:

18 Drivers

10hz – 20kHz Frequency Response

8Ω Impedance @1kHz

Integrated 4-way Passive Crossover

Our Analysis:

  • The U18t is meant for producers or artists looking for the most accurate sound reproduction with the best detail and clarity.
  • The U18s is tuned darker and warmer than the U18t. U18s sounds more similar to the U12t vs the U18t in terms of overall sound signature. Best for relaxed yet detailed listening.
