Can measurements and calibration be done easily at home to see if your sound system is well calibrated ?

I was thinking of playing a pink noise on the speaker and recording it with a cheap microphone or displaying it with the Spectroid app, but the microphone probably has it's own frequency response.

Is there an App for that ? With each phone model microphone factory calibrated ?

Is there a way to use known fact about physics like harmonics should have a specific shape (timbres) that's should help equalize frequency with respect to each other ? Or from various microphone positions, calibrate it so that any cheap microphone can do the trick ?

It's harder than that, because your ears have their own frequency response that can only be measured by your consciousness.

I've found a lot of enjoyment in equalizing as best you can with hardware, and then doing the finishing touches against your ears.

Take a frequency generator, I use a web one, and play a tone that matches your eq knob, and work your way through making sure all the tones are at the same volume. You'll have to do this a few times.

You might be surprised at how good it will sound. Especially the upper ranges which will usually be far too low if you only calibrated with mics and hardware and not your wetware.

Spot on. When you buy a measurement microphone, you can download it's specific response from the manufacturer.

A UMIK-1 is pretty cheap these days. Also check out REW.
