Regarding the PA5X140 by Galaxy Audio - I have a pair that I use infrequently. They sound terrible: way too much midrange that is nearly uncontrollable. I use them when I have guest vocalists because they are easy to setup and they are LOUD. You can plug a mic straight into the PA5X140 and then into the mixer so the singer gets their own monitor totally... but I wouldn't wish them on anyone on a regular basis. Try before you buy.
