I am currently helping my parents build a home audio system. Basically, we want to essentially put what would normally be a floor-standing speaker into the wall above a bookcase, then put some in ceiling speakers throughout the main level of their home, all running off of a speaker selector. The problem is that I have not seen a prefabricated speaker set that fits the area we are looking for. We want to build our own cabinet to fit and match what is existing, but I don't know where to buy only the speakers, the airspace requirements, etc. I'm pretty handy, and I worked in a car audio install bay for a few years, so I'm comfortable with the build and the wiring, just don't know where to get the speakers, grille cloth, etc. Can anyone help?
