I bought a scarlett 2i2, and go on. Mic calibration is not a must for ones like us. It is not too important if the spl is 74 or 73.
For the interface it is sufficient for my unprof measurements but i would be happier if it had also rca output, so i could use my headphone amplifier.
You can try...
we know that the most important thing is the total area covered with absorbers. The concerned freq about the ceiling bounce is 70-80 hz. This can not be fixed with a single small absorber. But speaker and listener placement plays a really huge role fixing that.
I made that mistake by buying small speakers to use with my subwoofer. There became an absence in upper bass and lower mids. Also if you get a better performer speaker you will have more chance to play with overlapping frequencies. With small speakers you will be limited
Even if your equipment is accepted to be flawless, you can not be sure of hearing engineers' target. There are many factors altering it like volume, room noise, your ear shape, your mental situation vs. Eq shouldn't be a phobia
I have a peak at 52hz and a dip at70hz . In fact i do not understand if it is a peak or dips beside it. I want to level match sub and mains. Should i equalize low end peaks before level matching?
That page calculates quantity of treatements needed. But i have better decay times than what is predicted with a lot of treatement. Does it make sense?

I founded that 70hz dip is about ceiling height. When a Hold the mic higher, 70hz spl is nearly 20db higher. Should i hang a thick absorber on the ceiling. Is it a reliable solution?
There is 1 foot distance between wall and a cabinet in my room. Can we put 6inch or thicker poreous absorbers into places like that. Or should they be on the walls. Not telling the first reflection concerned ones
They are close to each other so they build a massive peak. They hurt my ears. Smoothing maybe shows a nicer graph but doesn't help hearing. My sub has a hpf and mains also but i do not use them. Should i?
