Features · 2, 000 Watts program, 4, 000 Watts peak · Very low power compression · Pro RiderTM 15" woofer with 4" voice coil · RX22TM 2" titanium compression driver · Quadratic Throat WaveguideTM technology · Low distortion at high SPL · Sound GuardTM III high frequency driver protection Description The QW 3 is a three-way, full-range loudspeaker system employing a newly developed Pro Rider 15" woofer and an RX22 compression driver loaded by the high frequency section of a CH-746qt Quadratic Throat Waveguide. [. . . ] 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 3. Frequency response This measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the QW 3 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 3 combine to give a smooth frequency response from 50 Hz 16 kHz. Directivity Beamwidth is derived from the -6 dB points from the polar plots (see Figure 3), which are measured in a whole space anechoic environment. Q and Directivity Index are plotted for the on-axis measurement position. These specifications provide a reference to the coverage characteristics of the unit. The parameters indicate proper placement and installation in the chosen environment. The blending of components in the QW 3 exhibit a desirable beamwidth and directivity (Figures 3 and 4) suitable for sound reinforcement applications. Power handling There are many different approaches to power handling ratings. [. . . ] Copies of this statement may be obtained by contacting Peavey Electronics Corporation, P. O.
