I'm currently using mine for my PA in my studio. Due to space constraints, I've had to get a little creative. So I have my floor monitors creating a foundation, (and effectively being stored), against the middle of one of the long walls. On top of the wedges, (which are on their sides), are my two JBL mains, splayed right and left. On top of the mains is my Aurelex Gramma. On top of that is my Mackie 808S powered mixer. It seems to work quite well.
