This photo shows just inside the entry door to the bottom level. Due to the load bearing wall issue, this will no longer be part of the HT.
So now it serves as a staging area for the activities up the stairs. OOHH, it's a jammed mess!
The box on the floor is 500' of 14/4 oxygen-free, 105 strand per conductor speaker wire. "Audiophile Grade" of course, and RoSH compliant.
Eventually this lowest level will return as the music/fitness room.
