Great advise so far.
Though your listening room is small, it opens to a larger area, therefore it is not a small room, or a square space you are playing into. I would view this as a positive. Can the speakers play into (face) the larger space. Can you place your equipment rack at either side of your listening chair. Flexibility in the placement of speakers, listening position, and equipment rack is a true asset of a dedicated room.
Do research room treatment. GIK and ATS Acoustics are good sources for this, offering products and advise. I own a copy of Masters Handbook of Acoustics, it is worthwhile. Much on this in this forum.
I would work with getting the best sound from your system as-is, then consider component upgrades. I do believe a speaker upgrade would be the best place to start. With consideration to the amplification required for said speaker.
Are you using digital sources or only analog?
