Fiberglass insulation, the nasty itchy kind. Thickness 7 cm. The front and back got an extra layer of (real) wool felt (about 5 mm thickness felt). The panel is used in front of the wall with a little spacing (a couple of cm) in between panel and wall. Size is about 70 cm wide by 2.30 m high for the one on the side wall next to the speaker on the left. Another one much like it was used on the side wall near the couch. (both are behind the curtains on my photo's)
The panel behind my couch is a little less thick, 5 cm in thickness. Again with wool felt (I have bought a huge roll of it) on front and back.
The print for my poster/panel was ordered from Spoonflower, the fabric used was Kona cotton. Over on the AV forums that was tested as a very good material for that use.

Glad you got it working, keep working on it and it will only get better!
The disappearing act is fun! You shouldn't be aware of the speakers, let the music talk.
I used the compressed fiberglass panels with great success in a large studio/listening room. Easy to cover with fabric and make look very sharp.
An industrial heating/steamfitting supply company tuned out to be the best source.
At that type supply place, you can also find the dense fiberglass in cylindrical tubes (that go around steampipes). It can be split lengthwise to make attractive diffusion/absorption. Or if large in size, capped on the ends to make bass traps, which was my primary use.
PS.... beautiful happy looking kids !
I ran out of time before work today to make nice graphs. I can always repost them later.
The frequency response is measured from the couch from center l+r and three positions on each side l+r. I plan to measure 2 more per aside if needed. I kept the Equilizer APO eq settings active for the measurements but did not have any REW eq active with these.
The impulse plot looks much improved. I wonder if I'm just getting better at using the microphone and software.

Is the IR one of the measurements?
On the All SPL tab, deselect all right measurements so only the left ones are visible. Next click on the Controls button, upper right corner. You'll see a "Vector average" button there.
This way you can average all left channel measurements into an average.
Same principles for the right channel.
I'd like to see the Average IR of the left channel and one for the right.
Also the frequency curves that belong to these two IR's. We could fine tune the EQ based on these averages.
P.S. I noticed the threads you started in the Room Acoustics forum. A position closer to the corner can work, but the EQ needs to be adjusted for any position you might choose. These arrays have way too much energy around 200-300 Hz to make them pleasant sounding. You need EQ, these measurements can help correct your current situation, before adding room treatment.
The IR shown shows to mayor peaks to worry about. If I had to guess, I'd say the second peak is from the wall behind the listener. The first peak is actually more benign for your current imaging/tonality results.

Just came back from a friend's wedding weekend.
There was a speech by a lady friend of the couple and she said, "a happy wife is a happy life."
I guess it's kinda true! ha ha!
Glad she enjoyed the speakers!
I've taken a little time away from this project while celebrating Easter as well as my son's 1st birthday yesterday.
Wesayso, I've got improved graphs for you.
I think that first peak in the impulse plot is from the half wall behind my head. I tried adding couch pillows behind my head which seems to have made an improvement. I'd like to take measurements of that change on Thursday.
