*rated power measured with 2 hours test with pink noise signal, 6 dB crest factor, loudspeaker mounted on enclosure Thiele-Small parameters measured with LASER system
Frequency Response: enclosure volume 150l, port tuning 43Hz (thick curve on axis, thin curve 30° off axis)
Le: electrical inductance 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 45-1000Hz.
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
