User manual PEAVEY QW-2 DATASHEET

[. . . ] 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 52 Hz to 18 kHz. [. . . ] Its trapezoidal shape reduces the build-up of standing waves inside the enclosure, minimizing mid-bass and mid-range colorations due to the cabinet. It is constructed of premium . 720" plywood and is covered with a tough, durable black textured Hammer HeadTM polyurethane coating. A 16 gauge powder-coated perforated metal grille covers the front of the system to protect the speakers from external damage. An SA-1 stand mount adaptor is built-in for ease of speaker stand use. The two-way system is comprised of a 15" Pro RiderTM woofer with a Kevlar® impregnated, water-resistant treated cone and dust cap for superior environmental stability. Capable of over 600W of continuous power handling (AES Std 2-1984), the Pro Rider woofer can handle a lot of sheer power. The high frequencies are handled by a 44XTTM 4" titanium diaphragm compression driver, utilizing ferrofluid cooling, coupled to a CH 942qt constant directivity horn utilizing Quadratic Throat WaveguideTM technology. The CH 942qt is protected under US Patent 6, 059, 069, and due to this patented geometry, the horn has lower distortion than many popular CD horns. The 44XT driver features the Radialinear Planar Phase Correction System, under US Patent 6, 064, 745, which provides smoother and extended high frequency response. Input connection to the system is made via two 4-pin Neutrik in parallel, and a 4-pin Neutrik switching jack is provided for bi-amping flexibility while maintaining superior signal integrity. The inclusion of a standard 4-pin Neutrik jack in parallel on the driver side of the bi-amp switching jack provides for daisy chaining to another cabinet when bi-amping. The internal passive crossover features Sound Guard 44 tweeter protection circuit and an advanced topology crossover with high performance components to provide high power handling and reliability. [. . . ] The outside dimensions shall be 33. 38" high by 21. 13" wide by 22. 59" deep. The loudspeaker system shall be a Peavey model QW-TM2.
