ArcTec has developed a meticulous Quality Control sequence to make sure, that all products work within the predefined tolerance limits.

Each and every unit will be exposed to several measurements, these include:

1 – Impulse response
2 – Frequency response
3 – THD Total Harmonic Distortion
4 – CSD Cumulated Spectral Decay, and:
5 – Impedance

Left and right shells are measured separately, where it makes sense for
comparison the results are presented in a single diagram.

All results are summarized in a pdf that represents the performance of the unit under test The registered customer is entitled to download the pdf by typing in his specific serial number.
