Nominal Power based on a 100 h test using a 6dB crest factor pink noise signal filtered according to the IEC 60268-1:1985 norm and band-pass filtered with Butterworth 24dB/Oct filters from 89 Hz to 11,2 kHz.

Sensitivity and Max SPL measured using a 6 dB crest factor pink noise, averaged from 100 Hz to 10 kHz in 1/3 Octave bands.

Coverage measured from 500 Hz to 4 kHz in Octave bands.

Measured SPL obtained by integration over a period of at least 30 s.
