[. . . ] Frequency Response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the QWTM-4 is measured at a distance of 1-meter using a 1 Watt (into the nominal impedance) swept-sine input signal. As shown in Figure 1, the selected drivers in the QWTM-4 combine to give a smooth frequency response from 50 Hz to 18 kHz. [. . . ] As shown in Figure 1, the selected drivers in the QWTM-4 combine to give a smooth frequency response from 50 Hz to 18 kHz. Power handling There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a full-range form of the AES Standard 2-1984. Using audio band 20 Hz to 20 kHz pink noise with peaks of four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand today's high technology music. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available. Harmonic distortion Second and third harmonic distortions vs. frequency are plotted in Figures 3 and 4 for two power levels. Ten percent (10%) of rated input power and either one percent (1%) of rated input power or one watt, whichever is greater.
