Yes inside the book case; it will be a full wall built in. Good point about hole for cables!
Switching totems
I’m finding my totem sttaf speakers are great 3-4 ft from the wall but we re building a huge wall bookcase and I won’t have space to bring them out. Any suggestions? Nad 356 amp and nad CD player. I know arro is supposed to be good but what about bookshelf speakers that might literally just sit on one of the shelves or is that a ridiculous idea.
