Making speakers “disappear”…..

Right, I learned to set up LS3 5As back in 1979, the prototype for this sort of speaker. I was working for a HiFi shop in Miami, FL at the time.

As for speakers that can disappear you chose wisely, or just lucky? They need to be on stands with the tweeters at ear height. You want them just a little closer together than an equilateral triangle with your head. They need to be in a symmetrical environment. Three feet away or more from side walls and between two and three feet from the front wall. If one speaker is in a corner the other one has to be in a corner also. I would not want to see them more than eight feet apart. A 14 foot wall would be the max. I prefer corner placement. You will need to use some sound absorption on the side and front walls. 

You next mission should you choose to accept it will be subwoofers. You will need two, using a 2 way digital crossover with full bass management, crossing at 100 Hz. Why so high? To reduce distortion levels in that little woofer. In the process you will turn David into an absolute gorilla. 

I just set up this system for my son in law with Harbeth P3s. 

I did not initially see the post where you mention that the speakers are going on an 8 foot wall. You can place the Totems (on stands) 1 foot away from both the side and front walls but you will have to cover the side and front wall with acoustic tile from the corner to two feet in front of and to the side of the speakers, or three feet out from the corner. If you do not do this you will lose detail and your center image. On the bright side this placement will improve your bass. The other very important issue is that you want the listening position in the middle of the room, preferably the middle third but not dead center. You may also have to deaden the rear wall if the room is so small the latest reflections are still early.
