Polar test chamber showing speaker rotated 60 degrees on a lifter

For accurate and repeatable polar measurements of loudspeaker drive units, smart speakers, soundbars and active systems 

Polar test chambers are available in three sizes:

  • PTC2400, height 2.4m: measures at 1.0 meter
  • PTC1200, height 1.2m: measures at 0.5 meter
  • PTC600, height 0.6m: measures at 0.25 meter

Repeatable results

  • Results typically repeatable within 0.5dB (20-20kHz)
  • Controlled distance between the loudspeaker and the measurement microphones
  • Shape designed to minimize standing waves ensuring consistent low frequency response

Accurate results

  • Fixed environment which guarantees the measurement accuracy
  • Controlled pressure and high frequency environment ensure accurate wideband frequency response (20-20kHz)

Transferrable results

  • Structure and calibration of the chamber ensures transferrable results between chambers
