DESCRIPTION

The redesign of the ever popular SP4 has resulted in the SP4G loudspeaker system. It is a pseudo three-way speaker system comprised of a 15" Scorpion® Plus woofer with a Kevlar® impregnated cone and a 22XTcompression driver coupled to a CH® 941 constant directivity horn.

This unit can be driven in full-range or bi-amp mode simply by plugging into the desired jack on the input plate. The SP4G has a trapezoidal shaped box, rather than a rectangular shaped box, that allows arrays to be constructed much more easily. This shape also greatly reduces the build-up of standing waves on the inside of the enclosure. This ensures a minimum of mid-bass and mid-range coloration of the reproduced sound due to the cabinet. The SP4G is constructed of 3/4" plywood and is covered with Peavey’s durable black carpet. Polymer corners are also a part of the unit to provide added protection to the enclosure. A powder-coated, expanded metal grille covers the lower part of the front of the enclosure to protect the low frequency driver from unforeseen accidents.

Sound Guard, Peavey’s proprietary circuit for high frequency driver protection, has been included as an integral part of the crossover for the SP4G. The input signal is routed through the Sound Guardcircuit in both full-range and bi-amp modes of operation. When the high frequency drive level to the SP4G exceeds a predetermined threshold the Sound

Short duration transients will not be attenuated by Sound Guardand have the possibility to damage the 22XT. The Sound Guardcircuit is a dynamic circuit that will attenuate the signal more in relation to how large the signal is, very similar to a compressor. This is accomplished through the use of a specially selected, dynamically resistive
