~~~~Ah, You have a two story home. Thats another story!(sorry) If your home was built recently, you may have anywhere from a 7 to 11 inch space above the drywall, and joists spaced 12" to 24" apart. The joists that support a drywall ceiling in a one story home are a minimum of 2"x6". A two story home joists need to be thicker to support the added pounds per square foot load. Depending when the home was built, the span the joist must cover, and what was code at the time, would determine how thick of a floor/ceiling space you have.
~~~~Carefully probe through the drywall in a area that is not noticeable (next to a cabinet). Start with a pointed, small diameter tool. Do not go more than 5/8" in(thickness of fire code drywall). Then with a dull insulated probing tool, could use a piece of solid romex 15" long, or something non conductive and thin, gently push it up until it hits the floor of the second story. Hopefully you won't hit the joist on the first try. If you have a stud finder (not the kind at a bar) you can avoid a joist the first time. You may also tap with your knuckle and listen for a solid/hollow sound. Solid=joist, hollow=space.
~~~~Depending on which way your kitchen is oriented to the joists and interior walls, will determine the difficulty of the wiring. Only use wire rated for in wall use. Since you are not building a reference system, sonic quality of the wire is not a factor.
~~~~If all factors are favorable to ceiling speakers the next factor is which speaker to use. That will determine how you mount and support the speaker. I wouldn't use the drywall only to support the load. You should build a type of solid support inside the space to carry the load and not allow the speaker to vibrate. If an open back unit is selected, you may want to limit the volume of the space by inserting some type of partition and caulk to seal air space. If you have room you may want to install some bookshelf cabinets (wire, support, and trim out surface).
~~~~Is this starting to sound like a walkman would do nicely? Think about these ideas. Hopefully they will give you more options or spark more suggestions from others (other than things like, "Is this guy writing a novel or what!") My typing finger needs a rest. Remember, music soothes the savage beets (I had to!).
