What's the best way to install this box on sheet rock ceiling board?

Answer:
The box is meant to either mount to the Ceiling joist or to be suspended from the ceiling when dealing with a drop down ceiling. it sounds like you will be mounting the sheetrock to the joists so...
The box frame is 17 3/4" by 18" with the actual box meant to fit between two standard ceiling joists with the flange either screwed or nailed directly into the bottom of the Joist. Their is also a lip on the box which helps when cutting out the ceiling tile. Plus, once the box is secure it will help support the weight of the speaker as well.
Note: You can also increase the effectivess of the box by adding a fiber fill...
A significant increase in the effective volume of a sealed-box loudspeaker can be achieved by a filling of fibrous material, typically fiberglass, bonded acetate fiber (BAF) or long-fiber wool.
