The first quote for TV cabinet was aprox. $3,500 installed (unfinished). If the cabinets were deep enough, I intended to have them angled in, but not as much as your suggestion.
I planned to build an equipment rack into the closet that goes under the stairs to the left to keep the equipment accesible. That is what that little box was actually intended to be. I am looking for some suggestions on the best way to accomplish that too. I have looked into a couple of network racks that may suffice.
I was concerned about resonance in the cabinet too, especially from the subs if they were actually sitting on a shelf attached to the cabinet. Once I got closer to making a decision, I was going to have the contrtactor leave the bottoms out of the cabinets along the bottom, so they can sit right on the concrete floor. I could prorbably have them leave the backs off behing the L&R too to mount to the wall. Do you think there would be that much resonance from those too?
Thanks for the input.
