Here's one: Be absolutely certain of your speaker placement/wiring before the drywall goes up. think about it, think about it some more, and then think about it again prior to drywall day. If you are undecided, or think you may want to change your mind, run wire to support both options just in case you want to change the locations. Once the drywall goes up your pretty much locked in. I decided to change the location of my surrounds from in-ceiling to on wall after the walls went up. I was able to run wire through one of the walls after the fact, the other one was less accessible. I will end up using the Axiom flat wire along the ceiling to wire up the left side surround speaker. I'm hoping it will not be noticed by my better half.
