Speakers "Too Big" for room

I love the room. It looks like a great place to hang out. Great looking system as well. 

As you probably know, there is tremendous opportunity to improve sound quality through acoustic treatment. A larger rectangular highly absorbent rug. I think there are ways of making the curtains highly acoustically absorbent... so when you wan to critically listen you close them. Put flat absorbent panels behind, And these don't screw up the charm of the room. 

Enjoy the music!

You can do it effectively, just lots of acoustical treatment / dampening may be required so not to over load the room. You can basically acoustically enlarge the room by heavily dampening the walls, floors, and corners. The volume at which you listen will also play a role in how much treatment is required.
