But are you saying that I then should look before the 0 point
Left of the main peak zero are distortion components. Every peak is due to an increasing order of distortion component (2nd harmonic, 3rd harmonic, 4th harmonic .....). The further to the left you go, the higher the distortion order.

how to see that ?
If the energy arrived at the mic at two different times (i.e. phase shift in one driver), then there would be two main peaks after zero (although it's hard to distinquish from reflections). Perhaps set up in the middle of the room with the mic somewhat nearfield so you can determine the reflections better. Or even better still, do it outside.
