1 Measured on axis in the far field with 1 watt (2.00 V rms @ 4 ohms) input and referenced to 1 meter distance using the inverse square law. Listed
sound pressure represents an average from 300 Hz to 3 kHz.
2 Long-term maximum input power is determined by submitting the speakers to a power test lasting one hour, in which a special signal (IEC268-1)
is applied 20 times for one minute each, with an interval of two minutes between one application and the next. The special signal is generated by
filtering pink noise with a weighting device that bandpasses the signal with a 12 dB/octave slope below 55 Hz and above 5 kHz, and maintains the
6 dB peak/average ratio. The maximimum power the speaker is able to withstand without sustaining any permanent damage is taken as the value of
long-term maximum input power.
