Matt , you can also take comfort in the fact that we have room correction built into modern receivers which goes a long way to correcting the gross deficits in most rooms. Since you are building a dedicated room , I suspect the room correction will take care of all minor irregularities you may encounter. I have not read the book you mentioned but I did notice it was from 2008 and a lot has changed since then, including peoples willingness to properly prepare their rooms.
