82dB-SPL @ 1W, 1 m (pink noise)
Maximum acoustic output
93dB-SPL average in a 45,000 ft
room, with an RT

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.
