Frequency Response: enclosure volume 80l, port tuning 58Hz (thick curve on axis, thin curve 30° off axis)

Le: electrical inductance variation with voice coil displacement

Kms: stiffness of suspension variation with voice coil displacement

Cms: mechanical compliance variation with voice coil displacement

Bl(X): force factor variation with voice coil displacement

Power test done with intermittent excitation, ON interval 2min, duty cycle 50%, pink noise signal 6dB crest factor with frequency range 50-2000Hz.
