My friend is getting his house built, and the builder is offering to pre-wire the family room area for $2,500. I've never personally liked in-wall / in-ceiling speakers, and I think that is awfully expensive. My friend is leaning away from pre-wire. What do you guys think? Is $2,500 to pre-wire 6.1 too much? If looks didn't matter, are floor-standing speakers and externally mounted surrounds far superior to in-wall speakers in you opinion?
