An in-cabinet VP160 can be installed....
If you have extra room in the wall, as I have...
or
You can extend it into the room behind the wall, such as into a closet, etc. and it's not a major support wall where you can cut out a portion of a stud.
Agreed. After writing my post I thought of that option. I had already considered that option for my main listening area but did not have the wall depth. I don't have the wall depth in this situation either but may be able to do the in cab 150. I could allow the in cab 160 to sit out from the wall and build a little frame or something but that again goes against the look I was hoping to achieve. So now it looks like I am between another in wall M22 and in cab 150.
