Are in-wall speakers worth considering?


We're adding a family room to our house. It would probably be the best room in the house acoustically, but there will be too much going on in there to set up normal speakers properly. Are any in-wall speakers capable of providing decent sound?

The room dimensions will be about 14'W x 17'D x 9' H. The listening couch would be on the long wall, and the speakers would be mounted on the opposite wall (that is, firing across the shorter length of the room) and would have to be almost 10' apart due to placement of doors and windows. The floor will be carpeted. I'm sure I could squeeze a subwoofer into the room.

Thanks for any suggestions!

For some perspective here - I'm 22, love kids, and haven't asked for or accepted any compensation yet for stereo damage. None of the agitation is directed toward the kids and most of the irritation comes from the fact that these incidents are generally easily preventable. In fairness, I am sure that many of the parents lack a comprehension for what these incidents actually cost in dollars.

I am curious as to how others feel or react toward this kind of "ground damage".
I had my audio system in the living room and my video system in the den and the children would run into the living room with my audio system. As you can see(my attached system) it is not a safe place for children to play around (cut/burn themselves on amps, get electrocuted by the special powercords with air isolators... etc... It only took two times for me to wise up and move my 2 channel into my bedroom, and leave the video system (inwalls for others...)
To kinda get back on track here, there is another in/on wall worth looking at. Try the Legacy Harmony. I use them for the fronts in my HT, and every so often use them with the real music rig too. No need for a sub unless you are going to use them for HT. Take a look here.

To kinda get back off tarck here, I won't let kids in the room, period. Matter of fact, I don't let a lot of adults in there either. The dog & cat have more respect for my modest gear than some of my friends!
Can someone give me an intelligent, informed comment on the starlet series inwalls by speakercraft. Please, if you do not know S^%T do not answer.
