One tenth rated input power and one hundredth rated input power. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. = 2nd Harm. = 3rd Harm. 6. 0 dB 0. 0 dB -6. 0 dB -12. 0 dB -18. 0 dB -24. 0 dB -30. 0 dB -36. 0 dB -42. 0 dB -48. 0 dB -54. 0 dB 20 50 100 2nd & 3rd Harm. 6 MOUNTING: CAUTION: Before attempting to suspend this speaker, consult a certified structural engineer.
