The low voltage installer came by today and he mentioned that its better to run the cables to the outside of the house and drill back in rather than the drywall. The reasons he stated are:
#1 - Avoid the 1 inch hole in the wall that he would have to make to put the fish eye in.
#2 - Easier to patch the small hole while selling the house.
#3 - He also claimed that the wires and sound would not be impacted in the short or long term.
His quotes are the same whichever way I want to do it. ($50/speaker for labor)
I already bought 14AWG in wall cables so will be using them -http://www.monoprice.com/products/pr...seq=1&format=2
