That is exactly what they are. If they are angled enough for the 90 degree, will that not work for the mids and lows? The 50 degree may not be wide enough to cover the room, but it's only the center of the room that really needs it. Knowing they're a 90 degree angle, I'm wondering if we can hang them upright at the side walls, turning them in enough to catch the middle areas and outsides. Our downfall is having the sound hitting the middle of the room right at the stage, so that the house sound is louder than the stage sound. (This is a youth room and our teens like to be right at the stage area).
