The frequency response of the QW-1 is measured at a distance of 1 meter using a 1 Watt swept-sine input signal (into the nominal impedance). [. . . ] The power handling of this system in four-way applications approaches 6800 Watts program. Due to its high efficiency drivers, the QW-1 has a rating of 1200 Watts program for the mids, with a 44XTTM rated at 200 Watts program (band limited 1000 Hz to 20 kHz). For reference, the QW-215 is rated at 2400 Watts program and the QW-218 is rated at 3200 Watts program. The QW's patented CH®-642qt horn is loaded with the patented 44XT high efficiency compression driver and a BWX 1008-8 HE high powered mid, designed specifically for the QW-1. The horn has a coverage pattern of 60° in the horizontal axis and 40° in the vertical axis. The QW-1 is designed for arraying in flying applications or stacking on a stage. Twelve mounting points are located on the unit for flying applications. Three flying points are located on the top and bottom, and two points are on the right and left sides and the rear of the enclosure. The QW-1 is constructed with a special grade of high density 3/4" plywood and covered with a black Hammer Head hard coat, a tough finish equivalent to the durable liners used in truck beds today. This finish makes the enclosure very roadworthy, but more importantly the Hammer Head finish helps to dampen resonant modes that may develop. These minor, subtle resonant modes are dampened to help improve the overall sound quality of the system. 4 Ohms 4. 2 Ohms 8 Ohms 5. 4 Ohms Input connections: 2xNL4MP bi-amp MF and HF inputs in parallel Enclosure materials and finish: 0. 720 plywood finished in black Hammer HeadTM hard coating Mounting provisions: (12) 3/8"-16 threaded mounting suspension points (three each top and bottom and two each side and back). Use only forged shoulder machinery eye bolt, Mil Spec MIL51937-3. [. . . ] The nominal radiation geometry shall be 60° in the horizontal plane and 40° in the vertical plane.
