And I finally drilled into the side of one of those columns. (Down low where an outlet would be. I will be passing wires through this spot with a plate, so no harm no foul.)
Thicker than I thought at 3/4 inch. Was able to run a coat hanger up past where the horizontal piece is. Thats good. I am presuming I will probably find another 3/4+ of wood between the inside of the vertical piece and the horizontal piece. Right now I am not too concerned with that as I think the opening I will need to make for the center channel speaker will allow me enough room to get a drill in there to address it as needed.
I have been here for almost 5 years. I have had 2 false starts to getting new speakers.
I am NOT being held back this time. LOL
