Those are great PA monitors. There's a club near me which has a smaller room, the size of a small restaurant, and they have musicians in there performing regularly. They have ONE QSC 10.2 mounted, and that's all they ever need in that space. The QSC 10.2 is so good, it compares easily in performance and SPL (Sound Pressure, overall volume output) to anything made in the past decade that has a 12" cone.
Here's a video (https://youtu.be/QQJTEbbyC1Y) of a band playing outdoors with two 12" PA monitor outdoors. This is a show I recorded at the North Stonington Fair, and the sound you hear is what you'd hear from about 75-feet away in the stands. Note they have supplemented the PA with two subwoofers, but they are not using anything fancier than two 12" PA monitors for the main mix.
Two QSC 10.2's could handle a decent sized outdoor party or dance easily, and if you added ONE subwoofer, you'd be on par with the way the pros would handle this kind of show. The band you see in the video, Sugar, normally outsources sound reinforcement; this is about as simple a show you'll see them do.
Hope that helps - Have fun! :)
