Desktop performance speakers (that I can fly with...)

Hey y’all. I am doing a couple two-hour Sonic Pi seminars for some high schoolers in a month. I was originally planning on driving and just bringing my Rokits with me (because why not?), but have decided to fly instead. I’m looking to purchase some desktop speakers that I can pack in a carry-on. Any favorites in the $50 range? It’s not a big room and there will only be ~15 students in each seminar, so I don’t think I need anything huge.
