User manual PEAVEY QW-4 DATASHEET

[. . . ] Highquality, 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 50 Hz to 18 kHz. [. . . ] As an example, a 4. 0 3. 4 4. 0 3. 5 8. 0 7. 1 three way speaker system comprised of two 15" Pro RiderTM woofers with a Kevlar® impregnated cone, and an 44XTTM compression driver loaded onto a CH®942qt constant directivity horn. The QWTM-4 has a trapezoidal shaped enclosure, which reduces the build-up of standing waves inside the enclosure, which minimizes mid-bass and midrange coloration's 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. The quasi-three way system is comprised of double 15" Pro RiderTM woofers with Kevlar® impregnated waterresistant treated cones and dust cap for superior environmental stability. Capable of over 1, 200 W total of continuous power handling (AES Std 21984), the Pro Rider woofers together 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 jacks 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 biamping. The internal passive crossover features Sound GuardTM 44 tweeter protection circuit, and an advanced topology crossover with high performance components, to provide high power handling and reliability. Peavey's proprietary high-frequency driver protection circuitry, Sound GuardTM, provides long and medium term driver Input Connections: Two 4-pin Neutrik® Speakon® jacks in parallel for full range input, one 4-pin switching Neutrik Speakon jack with a normal 4-pin Speakon jack in parallel with the driver side for bi-amp inputs. [. . . ] The outside dimensions shall be 49. 25" high by 21. 13"wide by 22. 69" deep. The loudspeaker system shall be a Peavey model QWTM-4.
