I am trying to see if I can put in my 3 front "Kirksaeter Silverline Inwall 120" speakers in the wall that faces other houses on the street. I know that in-wall speakers are not the ideal but I am trying to make wife happy with this project as well. These speakers are very highly rated as far as in-wall speakers are concerned. My worry is, will I bother everybody on my street having them in an outside wall? Is there anything I can do to insulate them so noise doesn't leak outside the house?
