I bought these to use in my Church. The building is quite tricky acoustically so the line -array (lots of drivers in a line providing a point source) aspect of these is particularly useful. It enables easy focussing of sound without lots of mess bouncing off ceilings and walls. It enables long throw meaning that there is more equal volume distribution between front and back. This means that to hear at the back does not need the people at the front being deafened. I have a friend who gigs with the same rig with a 12 piece horn band. I would not use them for a large venue, full-on rock event, but for my purposes - 500 seater low/medium volume PA, they give very even coverage, good headroom, high quality sound with excellent intelligibility . I have to please people from 5 years old to 90 years old and everyone seems to be happy. They mount easily with the provided hardware and are so small that even the fussiest PA haters do not mind them. Sadly I still cop loads of grief about the mic leads on the floor. You cannot please everyone.
