Hi Bob!
The above may be cheaper, might not.
But likely a far higher SOF / WAF approval.
OR get decorator assistance / let her choose fabrics.
Our listening room is our L-shaped Lounge/Dining room, and all treatments so far were accepted by my wife. Decorator fabrics to cover them, were chosen, by her.
I'll be buying a Dspeaker DSP unit as soon as I can spare the cash.

DSP EQ can't fix basic room acoustics problems - Jon Risch 18:50:43 01/02/20 (1)
While it can be more effective than an analog 1/3 octave equalizer, it is no match for proper acoustical treatment, where sound is absorbed, diffused, and addressed directly for ANY listening location, rather than just one mic (or one area) location.

Again, by definition,a room-mode suck-out can't be EQ'd away, the energy still cancels and boosting the level near that frequency just pours amplifier power and speaker headroom into a black hole.

While acoustic room-mode peaks can be "EQ'd", that EQ is only valid for steady state signals, transients are then deficient in level, and this makes things sound weak and mushy in the bass.

Your FR curve can look pretty good, but still suck audibly.

  THANK YOU!!!! for saying that. It's refreshing to see that someone else here understands that. Sometimes, I feel like I'm talking to a damn wall when I tell people that DSP doesn't "correct" or "fix" a room. They look at me like I've got two heads.
  EQ'ing, whether digital or analog, changes the character of the sound radiated into a room, so that the reverberant and room modal sound has a different and possibly less bothersome character, but it does so at the expense of the quality of the direct sound from the loudspeakers. In other words, it DOES change the character of the loudspeaker output, but it DOES NOT change the character of the room!
  The term "room correction" is total audiophile bullshit.
  This is not to say that EQ can't help to mitigate some acoustical problems, by reducing their intrusion onto the quality of the soundfield, but it is by no means "room correction" nor a desirable way to improve the soundfield or the acoustics of a room.
  I sometimes explain it this way: Room acoustics is a frequency dependent and position dependent time domain issue.

Thanks, I'll research this as well.

  A dsp unit will have you going in circles, driving you nuts
