Advice on setting up Arc Ultra and Sub Gen-4?

Hello Everyone,

 I have finally pulled the trigger and purchased the Arc Ultra and Sub Gen 4 and want to install and set up both the items . Where should I begin? What is the best approach for setting up the Arc Ultra and Sub Gen-4? What steps are required—for instance, powering them on and then running the TruPlay procedure? I have a question and some doubt about performing the TruPlay process.

 I am unsure of the correct method because one YouTube video that I watched suggested that performing TruPlay while standing and moving the phone around the room makes little sense, since you will not watch a movie or listen while walking. The proper approach may be to sit where you will watch or listen, then move the phone near your seating area and around it. Is that accurate? 

Are there video tutorials on proper installation and setup? Any links to videos or articles could help. Finally, how should I choose settings for the Sub Gen-4 and for the Arc Ultra?

There are two aspects of Trueplay tuning for sonos home theater systems. It will have you sit in your preferred tv watching position and tune for that location. It will also have you move about the room. This aspect is tuning to the room dynamics and is also done when Trueplay tuning other sonos speakers.

Oh Ok, So if I understand you correctly, you are saying there is a TruePlay that needs to be done for your seated position and there is a true play which is done for the entire room in which you are gonna use the soundbar ? is that what you are saying ?
