I have the same room size (though I removed the closet door) and the same speakers and Class D Peachtreee Nova 150 integrated. I also keep the room entrance door open. My system sounds 100% better after adding the following GIK Acoustics room treatments. They cost $700 in total.

GIK will work with you over the phone to recommend treatment options. You can use something like photos or Facetime to show them the room.
BTW - I am going to put a bigger speaker into this room soon because the acoustic treatments now allow me to do this. I will not use any digital signal processing to help out.
