In stage monitoring applications sidefills are generally larger, full range speaker systems placed off to the side of the stage. The purpose of sidefills is to provide the performers a more enveloping and well balanced sound. This allows all performers to hear a good rough mix of the whole band, while still allowing for individual mixes to be provided for individuals at their position on the stage via wedge monitors. It is widely believed that the more full stage mix inspires better and more coherent performances among musicians. In past few years technology has made it possible to achieve a pretty full sounding mix at each position with relatively small wedge monitors so sidefills have begun to be used less. In very recent years in-ear monitoring systems have begun to render all stage monitors obsolete.
