Measurement

Measurement is based on an IEC711 coupler, a customized USB sound card and Win10 PC running ARTA Software.

Frequency Response measurement

Notice the bass, mid and treble are perfectly balanced. There is a slightly boost at 3Khz an producing a bright and clear vocal.

The Impulse Response measurement

CSD (Cumulative Spectral Decay), i.e., the waterfall diagram.

Notice the decay rate at 500hz-20Khz is very consistent, meaning less interference among bass, mid and treble.

Burst Decay

Notice the consistency among all the bands

Burst decay

Proceed with caution: dynamic drivers are with extremely fragile (1~5μm) diaphragm and can be easily damaged in following situations.

  • Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please heat the driver as little as possible during soldering.
  • Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. The fragile diaphragm may be damaged by having anything metallic hit it. 
  • Gluing: attaching glue either to the diaphragm or the backside holes may greatly alter the sound
  • Chemical: Applying any chemical solvent will void your warrant and we will not be able to help you
  • Others: applying high-voltage, storing in high temperature/humid environment… all may cause unrecoverable damage.
