PDFQW 4 Specifications (pdf)

The QW™-4F has two of the new extra-high power Pro Rider™ woofers incorporated, as well as a new compact cabinet design. The QW™-4F is a quasi-three way speaker system comprised of two 15" Pro Rider™ woofers with a Kevlar® impregnated cone, and an 44XT™ compression driver loaded onto a CH®942qt constant directivity horn. 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 Head™ polyurethane coating. A 16 gauge powder-coated perforated metal grille covers the front of the system to protect the speakers from external damage. Includes versatile flying points.

The quasi-three way system is comprised of double 15" Pro Rider™ woofers with Kevlar® impregnated, water-resistant treated cones and dust cap for superior environmental stability. Capable of over 1,200 W total of continuous power handling (AES Std 2-1984), the Pro Rider woofers together can handle a lot of sheer power. The high frequencies are handled by a 44XT™ 4" titanium diaphragm compression driver, utilizing ferrofluid cooling, coupled to a CH®942qt constant directivity horn utilizing Quadratic Throat Waveguide™ 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 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. Peavey’s proprietary high-frequency driver protection circuitry, Sound Guard™, provides long and medium term driver overload protection when the system is used full-range, without impairing musical transients or dynamics. The crossover provides driver roll-off and protection, as well as driver EQ for the woofer and horn. The sum total 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 50 Hz to 18 kHz.

Despite its compact dimensions for a double 15" based enclosure with a 2" throat compression driver, this system can put out some extremely serious sound levels, and take 2,800 Watts program of clean amplifier power, resulting in precise coverage with excellent clarity and high reliability.
