How much will the sound be impacted if I create a recessed shelf or cavity for the Arc of Beam soundbar under the TV? The Arc has both side and rear facing speakers so I fear that a small recess in the wall would create a problem. It looks like the Beam only has side speakers and no rear speakers to it might be better to at least recess partially.
My goal is to either fully recess and use speaker grill fabric to cover the recessed speaker or have it partially recessed so the front on the soundbar is even with the front of the TV, i.e., 2” from the wall. I have a Samsung “The Frame” TV and want to have a soundbar blend with the wall or the TV as much as possible.
