How to solve your loudspeaker testing problems
The weakest link in your measurement chain is your chamber, the new TTC chambers solve these problems...
- Anechoic chambers have massive footprints:
The TTC gives you equal or better results with a compact footprint - Achieving repeatable measurements is difficult in an anechoic chamber:
The TTC guarantees the microphone and loudspeaker positions - Anechoic chamber accuracy suffers at low frequencies:
The TTC is capable of measuring below 20 Hz - Results are not transferable between most test chambers:
The TTC meets international standards IEC 60268-21:2018 & IEC 60268-22:2020 - Most chambers are difficult to calibrate and awkward to use:
The TTC is calibrated and is ready to interface to your microphone and analyzer
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.

Repeatable results
- Results typically repeatable within +/-0.25dB (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
