I’m renovating my den and I’m putting in the Sonos Arc, amp, and 2 in ceiling speakers. I’d like to have the Sonos sub as well but I can’t leave it out and visible so I need to hide it somehow. I have a section of the wall in the corner of the room on same side as TV that is deep enough that I think I can create a wall cavity, put the amp in there, and then put a speaker grille in front. Do you think that will sound good? decent way to “hide” the sub?
