The EV is slight step up from what you are using, but I think you would benefit from a EVOX12 or a L1MII/F1. Since you and I generally approach weddings similarly, a sleeker, but just as good sounding system is the way to go. There are many benefits.
I've definitely mulled over the Evox systems. The Bose, I'm not really considering as a main. I love my compacts, and I'm by far not a Bose basher by any means. But the thing I love about them for ceremonies, cocktails, and speeches... is also the thing I hate for mains.
I prefer being able to focus sound on the dance floor, and leave the rest of the room able to speak comfortably. To do that, I simply believe in a traditional speaker model that lets me direct sound where I want it, rather than everywhere.
