How does one check for damaged speaker?

How do you know if a speaker sound "wrong"? The most obvious one is when speaker are wired in the wrong phases. But otherwise say your speaker has shipping damages(scratch, scuff, marks, cuts), how you would test that these kind of damage functionality?

Your speakers should come in a pair...

With any microphone, even your phone works, measure the frequency response with a free app or something.

If both measure the same I won't be too concerned.

I took some quick meaasurements:
Orange is L+R
Green is L
Blue is R

Looks alright to me, this is the JBL ES30, the mid range looks pretty good. ALso my mic cant measure above 10k so just ignore that part
