With above I would take measurements without the sub and move the speakers to see if that second hump moves with them.
Or take the speakers outdoors?

Indeed, and whilst the room sim is a useful tool it won’t be as accurate as the method you use. The room sim cannot take into account openings, odd shaped rooms, furnishings etc etc. In the last analysis, whilst measuring is a fantastically useful tool, it is only that when used with listening with one’s dear old ears and to one’s own taste!I have REW and a UMIK-1. I occasionally venture into measuring my room/loudspeakers to learn something. I have read the thread with interest but I wonder if there are simpler but still useful things that one can do.
I have personally found it useful to set up REW to generate noise [1] and then use the RTA (real-time analysis) tool while moving loudspeakers around in real time to observe how the frequency response changes at the listening position. I find I can moderate the peaks and troughs in the low frequency region to a useful extent, and this is noticeable in things like bass-heavy movie scores.
I am never going to get anywhere close to a perfect response this way. However the human ear-brain system adapts and I have found that I can make a useful improvement without aiming for technical perfection.
[1] White PN noise for the RTA tool in "Spectrum" mode (which is what I prefer) or Pink PN noise for the RTA tool in one of the "RTA" modes.
White noise puts more energy in the tweeters, keep the levels down if you use that.White PN noise for the RTA tool in "Spectrum" mode (which is what I prefer) or Pink PN noise for the RTA tool in one of the "RTA" modes.
Indeed. That's a very welcome reminder.White noise puts more energy in the tweeters, keep the levels down if you use that.
Yes. The final proof is in what you hear. In that respect I have been interested in discovering how much room equalization is "good enough" for my ears. I am quite sure "ruler flat" is not necessary to enjoy good sound and, more important, good music. My own experience is that simple improvements with the help of excellent tools like REW work very well without needing to buy more "stuff" to equalize the room to within an inch of its life.Indeed, and whilst the room sim is a useful tool it won’t be as accurate as the method you use.

The simulation of my room is quite busy with features, some of which correspond to measured and/or audible features and some that don't (or maybe I just don't understand yet). Plugging numbers into the simulator after positioning the loudspeakers using the noise + RTA method does indicate tentatively what matters in the simulation and what to ignore. I would not understand that from just believing my interpretation the simulation without the practical evidence.Wouldn’t it be more convenient to ‘virtually’ move your speakers/listening position in the room simulation feature?

IME measuring both speakers at the same time is far more likely to produce spurious results in the middle and high frequencies than measuring each speaker individually.
IME, any measurement committed to screen or paper may look offensive to the eye, but that doesn't mean it will automatically be offensive to the ear.Thank goodness all the plots of my horrific in-room responses have expired. My system sounds so much better now
