The home theater systems also come with new speakers.

With your floor plan I think you may have the same problem I faced, specifically a fairly small slot in the cabinet where the box fit. And speakers mounted in the cabinet above the TV. I measured my opening for the box and the speaker size and went to Best Buy. They had several models of home theater systems from different manufacturers. I bought one small enough to fit in the opening. And that had speakers as close to the size of the originals as I could find. Unfortunately even those were slightly larger and I had to enlarge the openings a little to fit them in. Also had to get new ceiling mounts for the rear speakers. I suppose I could have used the existing speakers but chose to use the new ones and they do sound better.
