Each project is unique. You can use 2 ceiling speakers or just one stereo speaker if is small the area. In some cases I use a sound bar with 32 inch TV’s. (You know, some customers use this TV in kitchen more than his bedroom TV).
Honestly, in this is places nobody comes to hear music seriously. It’s nice for listen radio news, ambience music or some podcast, so dont worry so much about the specific location of these speakers.
