1
Measured on-axis in the far field with 1 watt (2.00V RMS @
4Ω ) input and referenced to 1 meter distance using the
inverse square law. Listed sound pressure represents an
average from 300Hz to 3kHz.
2
IEC Spectrum, peak for 2 hours with +4.5 dB crest factor.
3
Recommended Amplifier is a power capability value that
should be taken as a guide.
