Hi. About to move to an apartment with the following layout. the only place the TV can go is circled red and where the couch can go is in blue. I'm concerned about losing one of the surrounds from the era 300s due to one side having no wall at all and extending to the other side of the apartment. Any tips on how to mitigate this when I move? My thought was to place a bookshelf in that area, next to that era 300, so as to create something that sound can bounce off of.
