Trying to figure out what to do.

I don't know my neighbors very well. It's the weekend and they're having a party. They have been playing very loud music (with house-bouncing bass) since about 9:00 p.m. and it's now just past midnight. Even though I can be spicy online, I'm not confrontational in person, so I don't want to go over there and politely ask them to shut up or at least turn it down. Also this is the first home we've ever owned, so if I start some kind of beef with our neighbors, we can't just pick up and move to avoid drama. I'm not going to call the police because it's not a real emergency and any time the police are involved, innocent people end up in peril. I am tempted to get my biggest speaker, point it out the window and blast Vivaldi, but aside from amusing our household I don't think that's going to fix anything.
