Wow! Thanks for the response. I had found it hard to believe that an in-wall speaker could supply high quality/consistent sound. I'm coming from a "Vance Dickerson's Speaker design cookbook" back ground, and I have put so much time in box size shape and port tuning that throwing speaker into a wall seemed a little scary. I guess I'm going to be forced into this one though.
Another option could be Yamaha's new sound projector...just add sub. This way I dont' have to cut large holes in the dry wall and, in all honesty, it would be a fraction of the cost.
Anyway..thanks for the suggestions.
