On the large side of things, I bought a cheap PA setup from monoprice for outdoor events and karaoke. Two self powered 15" plastic boxed PA speakers, stands, cables, a wireless mic set from Amazon. I have under $400 into everything (less than my last cable upgrades for the main rig). I hook up a phone or a laptop for the source and everyone loves it. I can host or take the whole thing to a friends house. Plenty of sound.
On the small side of things, the weather proof JBL Charge bluetooth speakers are fantastic. Link two of them together and use a phone as a source and you can fill any room with sound. My dad puts a set on his deck for outside listening and small gatherings. You can pair up to 100 speakers if I remember correctly (running in mono) so you can always add another one for more sound.
Both good options depending on what you are trying to achieve.
