I'm having trouble pulling up the room image but yours sounds rather drastic for audio but not to worry. My own room is a combination of walls of windows with Rocky Mtn views I will not ignore. Almost every other space of bare wall is covered with oil paintings (luckily not more glass). I love my space. It's for scenic beauty, music, and art and literature (separate TV area).
If you have a primary position/chair for listening (or TV) then I'm with golfmd2 in recommending room correction as the single largest bang for the buck you will ever hear. I use a DSPeaker Anti-Mode 2.0 Dual Core and I promise you that you will not hear a larger improvement in the sound of your system once you room correct for bass peaks.
That DSP is under $1000 and it seems many outside our community can't really hear much so adjust for your chair and don't worry. With the apparent liveliness of you room (somewhat like mine) you can easily dial down the treble highs due to reflections. Hearing good speakers correctly and properly equalized for a room is an absolutely stunning A/B revelation. (Trying to boost nulls is a joke. Don't.)
I'd have originally said DSP and a sub, for cheap: an SVS SB-3000 (pretty amazing-I have one). I use an REL Britannia B1 so I think you'll be thrilled with those new S/812 subs. I'd beg you to try the DSP unit and I'm positive you will only have good things to say when you dial it in; I'll never sacrifice mine and it made good Raidho D2 speakers sound even better. Good luck.
