I was going to attach a pic, but I can't find the attachment button, just an image link  - its probably right under my nose... 

On the front wall, above the fireplace or above the cabinets on either side of it, I have attic access from the other side of the wall and can make a full custom enclosure for that and use any type of drivers I would like if I'm not likely to get anywhere with regular in wall/ceiling speakers.
