How do you know whats blown?

I was checking the levels of my speakers this afternoon - and noticed my one speaker was quite a lot deeper (lower) than the other at the same level - I thought it might be positioning, so I put them next to each other, same thing, tried swapping the cables around, same speaker was lower/deeper - if I put its level at about -4dB while the other one is at -5.5dB they measure the same dB on my meter, but the one still sounds deeper... I'm assuming this would be the tweeter? If I play music through one channel at a time, they both sound fine, except the one does sound deeper.

Excuse my beginner level speak
