Speakers for yoga studio

I'm opening a hot yoga studio and looking for simple speaker suggestions. Real simple would be a couple of JBL Xtreme 2's, or SVS makes a wireless bookshelf speaker (simple for teachers to connect to with Spotify or Roon) Alternative could be something a little larger or vintage mounted up in the corners. There will be a sub mixed in with the yoga blocks near one corner of the room. Kind of thinking good tone over dynamic slam- it's yoga, but there will be some high intensity interval training classes with a boogie factor.  

Appreciate your thoughts. Budget for mains around $500-800.
