DESCRIPTION

The SP™ 1G is a step up to a higher performance loudspeaker system within the SP line of enclo- sures. It is a two-way loudspeaker consisting of a 15" Black Widow® woofer and a 44XT™ compression driver loaded with a CH® 7 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 trapezoidal design of the enclosure allows arrays to be constructed much more easily than when using a rectangular shaped box. This shape also greatly reduces the buildup of standing waves on the inside of the enclo- sure. This ensures a minimum of mid-bass and midrange coloration of the reproduced sound due to the cabinet. The SP™ 1G is constructed of 3/4" plywood and 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 enclo- sure to protect the low-frequency driver from unforeseen accidents.

Sound Guard 44XT™, a version of Peavey’s proprietary high- frequency driver protection circuit designed especially for the 44XT™, has been included as an integral part of the crossover for the

SP™ 1G. The input signal is routed through the Sound Guard 44XT™ circuit in both full-range and bi-amp modes of operation. When the high- frequency drive level to the SP™ 1G exceeds a predetermined threshold, the Sound Guard 44XT™ circuit is

engaged. This is achieved at approximately 90% full-rated power with most program material. The effect that this has is to decrease the signal level going

to the 44XT™ by about 6 dB so that it will not be damaged due to long term (thermal) overpowering. Short duration transients will not be attenuated by Sound Guard 44XT™ and have the possibility to damage the 44XT™.
