Contoll room Question

hi I'm new here, I have a question a bout a control room I'm about to build it's quite small 3m x 3,5m and the ceiling is 2,7m there is no room to build a bass trap on the back wall cuz there is a door in there so I have 3 questions 1. On my sketch of the room I have a basstrap on the middle of the back wall, will this work? 2. Is the room big enough for a 5.1 speaker system (genelec 8000 series)? 3. Is it possible to have the speakers high up pointing down to ad distance from the speakers to my ears? I hope this is enough info. plz let me know if you need anything else Eiki
