Ejlif is correct. I left my ceiling opened. In order to keep it cleaner and sounding better, I sprayed the entire ceiling with primer/paint. It looks acceptable now.
I did do one other thing: I put in a floating floor over the concrete and then a huge carpet. This really decoupled the speakers from the concrete, warmed up the room and protects everything from the moisture concrete will leech over time. Floating 2x2 squares can be bought at HD or Lowes. Simple wooden squares with plastic backing that interlock.
