I have my new DLP rear-projection screen on order so it's time to get my 5.1 speakers setup properly for the first time since we moved into this house. Unfortunately, this room also has to double as our main family living area complete with playpen for the twins! I have attached a plan of the current room layout and I'd be grateful for suggestions of where to put each speaker for the optimal 5.1 soundstage for this difficult room! I am not adverse to moving furniture around if required but and structural modifications (eg, remove fireplace!) is out! Thanks in advance Paul.
