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, 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 0.5dB (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
