Amplitude at frequency is one piece of the puzzle. The real question is where the dip or bump is. From 1.5k to 3k a bump will create a bright speaker and a dip will create a polite speaker.
Having said that measurements can be misleading as microphones include the direct and indirect sound…microphones are stupid compared to our brains.
As long as the reflections are delayed a bit, our brains can separate out the direct and indirect sound.
When people make manual adjustments to frequency response based off a microphone, mids and treble can sound off as the direct sound is being altered, potentially making things worse.
