If you have a large room like this, you must live in a mansion. That said you will have a difficult time filling that room with sound. If you can afford a room that size in your home, you can certainly afford a larger size system. That is a huge room. Perhaps install a system with speakers in the ceiling to hear music throughout this room. Not sure how to image a sound stage in such a large space. There are a lot of very knowledgeable people in this group to get advice. Perhaps include a picture of the room you are working with. Perhaps, find a smaller room in your house to set up a listening room.
