Do I notice some nice warm glowing bottles in that rack?
Very nice
Those panels are made of OC705 or equivalent I'm 99.99999% sure. They'll work fine in your application for a variety of things. If at all possible, I'd pull the speakers out to get them in front of the armoire. Gotta let those tubes do their single ended imaging magic!
If you must sit so close to the wall, a min of a 2-3" panel or two behind your head will help control bass at the boundary. Make smaller panels for the folding closet door. Push the rack against the front wall to allow a panel on the left wall to do it's job of catching reflections and creating some symmetry.
