Just one. Bose really sticks it to you on these. You would think since you buy the speakers in a set of 2, they would give you 2 brackets in a package, especially considering how much they cost. The brackets allow you to either wall mount or ceiling mount the speaker, but you will need to buy 2 brackets, one for each speaker. And, there invisibility claim is also misleading as you still have a power cord that plugs into them and has to be hidden in your wall or in a cord cover.
