You can use a Sonos Amp with any ceiling speakers.  Note: If you wish to power 2 pairs with one Amp, they need to be 8 Ohms each.  If you wish to power 3 pairs, you need to buy the Architectural speakers available here:

Excellent advice from ​@jgatie. However, as it seems you only have one Sonos speaker you might want to elaborate as to why you want to install ceiling speakers. At the very least community members may be able to make suggestions based on your need; before you invest in a Sonos amp and speakers.

Sonos does sell Sonance in ceiling speakers themselves, but many other companies make speakers that will connect to the Sonos Amp, as ​@jgatie says. ​@AjTrek1 has a point, more knowledge as to the circumstances might help this community’s members give you more concrete advice.
