64 Audio – U12t

4-Way, 12 drivers configuration

The 64 Audio U12t covers a very wide range of frequencies with its 12 drivers. 4 BA drivers handle the lows, 6 for the full-bodied mid-range, 1 for the higher mids, and 1 dedicated driver handles the treble. At around 12ohm impedance, the U12t is easy to drive with any source. In addition, the 4-way passive crossover defines all music with plenty of resolution.

LID technology

Linear Impedance Design (LID) is a patented circuit that corrects the non-linear electrical resistance of the multiple driver-sets comprising this 12 driver IEM. Varying source amplifier output impedance in devices like smartphones, body packs, DAC/amps, and DAPs typically results in varying frequency response across them, depending on the increase in resistance. Restoring proper interaction with the source and preserving the desired sound signature enables a consistent reliable sound.
