Master Process Speaker Placement

[ngc4900]

Hello

I linked Dan's excellent post back in 2014 regarding the "Master Process Speaker Placement technique so I could ask questions regarding definitions, nomenclature, and techniques that I do not understand.

http://www.audioaficionado.org/617307-post30.html

At the end of step 2 the statement "if you can get to this point you should have better sound than 98% of the speaker set ups out there.

This statement intrigued me so I decided to take my time and work on learning steps 1 and 2.


A few questions

Toe in the left speaker so that the tweeter points to a spot about 18" behind your head

How does one measure this? Is this done while sitting in the listening seat?

Step 1: Set the Anchor. Start with the left speaker only. While doing your best to maintain toe-in, move straight forward from the wall in a smooth motion.

Does this mean you are moving the left speaker away from the side wall towards the middle of the room or away from the back wall (the wall behind the speaker) or both?

Thanks so much for the help.
Joe
