Speakers for playing music in a lobby and other rooms

I was hoping to use volumio on raspberry_pi to play music in my building. I have it easily playing Spotify and music on the SD card out the regular audio port.

I’m trying to find cheap speakers that can connect to wifi and receive the audio and play it. Obviously I don’t want it to sound really bad, but audiophile quality is not a requirement.

As I’ve looked around, I’m starting to think that I’ve approached this wrong. Can volumio do this? Anyone know of any speakers? $50 or under would be ideal.

Thanks for any help.
