Bob Robbins' setup guide

I wouldn’t say heavy toe in in at all but due to my room one speaker has more toe in.  Also i do i have some up tilt.  It was weird to watch as once we got the speakers lock into the room for bass it was just back and forth to create a great center image. Then it was just rake up to create the proper height.  
 

if you have good ears and memory w each adjustment it is pretty straight forward.  I just get lost in all of the changes so i had the master come in and set mine.  
 

follow the instructions and take your time.  Things will snap into focus. 

This set up takes a lot of patience and can be physically and mentally exhausting.  When I set up the left speaker I focus on the quality and impact of the bass but also how clean, clear and smooth Jennifers voice is.  You have to go slow and after you find a few good spots you need to move the speaker a millimeter at a time till it sounds best. 

The right speaker may not necessarily end up the same distance from the walls as the left.  You center the image but you also have to pay attention to the bass clarity and smoothness of the vocals.  It will then come together but I have not been able to get the center image to float in the center as well as I would like but may be a limitation of the Klipsch Forte speakers I am using.

I have been shoving speakers around many sound rooms for decades, used the rule of thirds, fifths, sevenths, and used the Cardas set-up.  This Sumiko method seems to make the speakers sound their best but you need to have a lot of patience and a forgiving household.              

I have been doing this speaker placement method for years, ever since hearing it at RMAF 2007. It is hard to do however, and it took me about 10 years to get it right. And then I sort of wondered why it took me so long.

That locked center image is when you have properly done it, otherwise you are just close but not really there. It is tricky because the locked center image occurs with just a small movement of the second speaker in the procedure.

The Colorado Guy YT video is pretty helpful for certain aspects, and it is recommended. The step guide in AudioAfficianado is very very good.

An alternative way to get the locked center image is to use a mono recording. When you have the locked center image, that image stays in place as you move around the room. It is easier to hear than any stereo recording.
