How to solve your loudspeaker testing problems

The weakest link in your measurement chain is your chamber

  • Typically chambers have massive footprints:
    The TTC solves your problem with its compact geometry
  • Typically chambers don’t result in repeatable measurements:
    The TTC solves your problem by fixed microphone and loudspeaker positions
  • Typically accuracy suffers at low frequencies:
    The TTC solves your problem by measuring below the low frequency limit of your driver
  • Typically results are not transferable between chambers:
    The TTC solves your problem by using internationally accepted standards
  • Typically chambers are difficult and awkward to use:
    The TTC solves your problem by allowing quick changeover of loudspeakers

The TTC establishes a new normal for R&D and production line loudspeaker testing

After an exhaustive peer review the concept has been included as part of IEC 60268-21:2018 & IEC 60268-22:2020, and AES73id-2019.

The TTC delivers results better than +/-0.5dB 20Hz to 20kHz to a 95% confidence level.

Find out how affordable it is!

Repeatable results

  • Results typically repeatable within 0.5dB (20-20kHz)
  • Controlled distance between the loudspeaker and the measurement microphone
  • Tetrahedral shape eliminates 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

  • Tetrahedral structure and calibration of the TTC ensures transferrable results between chambers
  • Meets IEC 60268-21-2018, IEC 60268-22 ED1, and AES 73id-2019 standards
