[. . . ] The inclusion of a standard four-pin Neutrik jack in parallel allows for daisy chaining to another cabinet when bi-amping. Despite its compact dimensions for a single 18" bass enclosure, this system can produce some extremely serious sound. Frequency response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the QW-118 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 QW-118 combine to give a smooth frequency response from 47 Hz to 1. 5 kHz. Power handling There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a modified form of the AES Standard 2-1984. Using audio band 40 Hz to 400 Hz 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.
