Portable speakers for meetings with 80 attendees

I mainly do IT but have enough AV skills/experience to run a few meetings each year. Renting is getting pricey, so I'm looking to complete my equipment inventory with a pair of portable speakers on stands, for a room that usually holds 80 people. These are educational meetings where people just present a powerpoint and speak into a podium mic. Occasional use of a wireless mic for audience Q&A. Barely any music.

Since it's only 2-3 meetings a year, I'm not looking to spend a lot....would like to get away with just spending around $200 per speaker, if possible.

What would you recommend?
