Also a thick blanket over the back might help too. I also have leather and always cover my couch back even when running audyssey. And yes, I do cover it when listening intently to music.
I always struggle telling reflections that cause anomalies.
I ran some measurements with a thick blanket that covers the entire back but it changed very little.

No and I wont either as I want to measure the sound at the listener position. Moving the seat further away from the wall will put me too close the main speakers. I could try a couple of more inches I suppose.
Gotcha....

Sometimes it won’t change much. Sometimes it does if the mic is picking up reflections off the seat backs. This can do weird things, but mostly i think cause cancellations.
I have AudiOCD sometimes and well....you know...lol

Have you tried putting the mic above the seatback and further away from the wall?
I lied to you yesterday, March 22 at 10:am. :p I decided to raise the mic up by a couple of inches just passed the chair back which made it slightly higher than my ears by an inch. Here are the revised measurements

While the weather is nice and the daylight hours are long, I will not spend much time on getting the new sub integrated into the system. Thankfully, I did keep my old measurements when I went through this exercise looking for the best location for the current sub.

The new sub location frequency response is this

Out of the next three locations, I will locate the 2nd sub to the right of the sofa almost opposite corner of the new location.

The other two locations were left of sofa and by the exercise bike.

I got the 2nd sub dialed in I think. Here is the raw response before adding a house curve via the miniDSP. The 2nd sub was first gain matched my ensuring the SPL at 50 Hz was the same for the 2nd sub at the 1st subs location.

Still learning about REW and miniDSP. Are most of you using the miniDSP just on the subwoofer? Basically, using Audyssey / YPAO / DIRAC for the mains and surrounds and miniDSP between the sub/LFE out and the subwoofer input?

Correct in my case and for a few others here.

Yes. I use my mini for the three subs in my system. I also use audyssey xt32 with subEQ but have been limiting to 300hz and using bypass on my mains.

The miniDSPs I have (2x4 models) were purchased for sub setup, altho the older one, an unbalanced, is set aside for a future diy 2-way active speaker project....someday :). I'd need a more capable one for a ful multich speaker array as well as separate amps to stick 'em in between the avr and speakers, tho.

The 2nd sub location in the basement and its firing out from the back wall.

The first graph are plots along the width of the couch before EQ via miniDSP.

The second graph are plots along the width of the couch post EQ via miniDSP

I'm going to have play with the EQ a bit more with the miniDSP as I'm not satisfied with the drop in output from PreEQ to PostEQ and the difference between the 3 LPs

So I've done more playing but to lazy to measure today. Instead, I'm posting a graph of what MiniDSP thinks it can do for me. I've also attached a screen shot of the settings in REW

Looks OK on a screenshot, but will have to see how it actually sounds. Sometimes the curve looks right but doesn't sound as good as it looks, I find.
