[. . . ] The result is a clean, clear and smooth response. High quality, reliable crossover components include polypropylene capacitors and high-current inductors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from the QW-Monitor. Frequency response This measurement determines how accurately a given unit reproduces an input signal. The frequency response of the QW-Monitor is measured at a distance of 1 meter using a 1 Watt swept-sine input signal (into the nominal impedance). As shown in figure 1, the selected drivers in the QW-Monitor combine to give a smooth frequency response from 67 Hz - 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 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 amplifier headroom available. SPECIFICATIONS QWTM-Monitors Harmonic distortion Second and third harmonic distortions vs. frequency are plotted in figures 3 and 4 for two power levels, 10% of rated input power and either 1% of rated input power or 1 Watt, whichever is greater. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic.
