SAM lab tour in Norway this week

[ogs]

Around 5 minutes. Much of the measurements are automated. No microphone is used, just a laser pointed close to the speaker membrane. The operator adjusts a few parameters during measurement. The XMAX setting (maximum safe cone excursion before distortion sets in) is done manually by playing a low frequency sinus tone while slowly increasing the level on the amplifier until one can see distortion increase in the SAM program on the PC. Mine ended up at 7 millimeters. Very nice for my use!
