Wavecor TW022WA06 sound pressure & impedance (dispersion)

Wavecor TW022WA06 amplitude and impedance (dispersion)

Very good linearity with a slight increase from 2 to 7kHz, which can be easily equalized with the crossover and / or a clever arrangement on the baffle. From 15kHz slightly decreasing amplitude response. Full level from 1kHz, with an average efficiency of 91dB / 2,83V.

Both drivers are practically congruent in the frequency response as of 1,5khz.

There are no disturbances in the impedance path. In both drivers practically congruent.

 Wavecor TW022WA06 Sound pressure at angles (15 °, 30 °, 45 °, 60 °)

Wavecor TW022WA06 Angle Measurements 0-60 °

Extremely uniform omnidirectional behavior thanks to the sound transmission. The combination of sound guide and dome is extremely well done.

Wavecor TW022WA06 Lingering behavior

Wavecor TW022WA06 Lingering behavior

Even and very fast decay over all frequencies. No criticisms

Wavecor TW022WA06 harmonic distortion

Wavecor TW022WA06 harmonic distortion

The harmonic distortion is sensational for such a small (22mm voice coil) calotte. K3 remains below 95% even at 0,15dB, starting at 1,3kHz.

K2 increases slowly below 3kHz, but still allows for a separation around 1,5kHz. Even with such a deep separation, the 1% mark would not be reached. Higher-order distortion components are completely negligible. If you aim for very low-distortion loudspeakers, it will separate at 2kHz.


Frequency response / directional behavior:4.5 5 out of stars
Range:4.5 5 out of stars
Power handling:4 5 out of stars
Series constancy / without rating:0 5 out of stars
Haptics:5 5 out of stars
Price-performance:5 5 out of stars


Wavecor TW022WA06 does not have any weaknesses in metrology

  • wide frequency response
  • very good omnidirectional behavior
  • sensational (for a 22mm voice coil) lower K3
  • very good workmanship and touch quality
  • Can be used from 1,5kHz !!!
  • supposedly very low dispersion

... and all for a very affordable 45 € (as of October 2013)!
