1 Full bandwidth pink noise is amplified to a level at the loudspeaker terminals corresponding to 1W as referenced to the nominal impedance.The average sound pressure level (dB-SPL) is measured at 1 metre from
the speaker in an anechoic environment.
2 Full bandwidth pink noise is amplified to a level at the loudspeaker terminals corresponding to the long-term rated power handling of the speaker.The average sound pressure level (dB-SPL) is measured at 1 metre
from the speaker in an anechoic environment.
3 Full bandwidth pink noise,meeting International Electrotechnical Commission (IEC) Standard #268-5, with a spectrum corresponding to average program material.
4 Full bandwidth noise,meeting the IEC Standard #268-5 is amplified to a level at the loudspeaker terminals corresponding to the power handling of the loudspeaker.The loudspeaker must show no visible damage or
measurable loss of performance after 100 hours of continuous testing.
