Loudspeaker measurements
- Thiele/Small parameters and standard small signal parameters
- Large signal parameters as function of voice coil excursion
- 2nd and 3rd harmonic distortion
- Intermodulation distortion
- Multitone distortion
Loudspeaker validation tests
- IEC-60268-5 Rated power test
- IEC-60268-5 Long-term power test
- Step-up power test (Combine Mechanical & Thermal Stress)
- Power test with any kind of input signal (level, crest factor, frequency range, music)
- Identifying voice coil temperature, magnet temperature, cabinet temperature including ambient temperature
