Sanity check: Bad Sub ? (REW Sweep results)

Yeah, though trying combinations of speaker settings AND combinations of positions is difficult, so I was measuring at the sweet spot seat.

I think I'm done for now, at least until I decide if I am going to buy Dirac Live. Or I guess Multeq-x, but DL seems more appreciated generally?

Anyway, it was a useful exercise. I found two rattles around 50-70hz, one a foot on the Q11 I had not tightened, and the little sub has hard feet on a hard floor, and literally was vibrating up on one or more feet and clacking.

From that position this is the combined subs sweep going through Audyssey (I was surprised, it tested each sub individually when it ran, this is the in-AVR versinon). Much flatter than I started. Not flat, but better.

I'm not sure if this is a valid test or not, but it's a stereo only output sent to it thru L+R with multi-channel on (which I think does a lot of processing to split it up and send it to various speakers). Not sure if it's good or bad, but it's also kind of sort of flat-ish for all 7 speakers combined.

Probably more importantly I played some movie clips with interesting sounds (like the first Stranger Things opening at the elevator, or various pieces from Star Trek's (Chris Pine versions). They all sounded good, and I think better than before I started messing around with it.

Whether someone with better ears, and more experience, would think it horrible or fair I don't know. But I have old ears and little experience and I'm happy so far.
You may be overthinking things :). There's reference, then there's preference. Might check this out in any case https://www.audiosciencereview.com/forum/index.php?threads/the-moving-microphone-method-mmm-for-dummies-using-rew.51333/
