"Yep I used the manual. Don't recall it being specific about the amount of tilt. No substitute for dialing it in with listening though. The stand up, sit down test is very revealing if there is too much tilt."
If you go through the manual, its the part where you hang a string off the back of the speaker (you tie something to the end of the string like a nut to keep it straight). Once the string settles, you measure the distance between the string and the bottom of the base of the speaker. That's your back tilt. How much is determined by all of the other setup factors, so you should know beforehand how much you will need. I think the last time, for me was about 1/2 an inch. If I were to move things around, though, I would have to set the tilt again to account for the changes. I know some people use a lazer level but the string is easy enough that I don't see the value in spending the extra money. Going back to what you were talking about noticing the differences when you stand up and sit down, yes, its a big difference and that's why back tilt is do important to get right.
Greatwhitebat,
After seeing your drawings, something tells me not only will you make light work of setting these speakers up, but you'll really enjoy the process. I wouldn't be shocked if you already have a lazer level. lol. It looks like you have plenty of room to either move the speakers out further in the room, or move your couch closer to the speakers. If you can, I would split the difference and do a little of both.
