Does this mean that my 250 usd Presonus Eris E5 which is +-2db from 50hz and up sounds pretty much like the Genelec Ones although much more expensive? (Discounting DPS options and how they would play different in my room)They don't.
If you measure at the listeners eardrum and two speakers measure at your eardrum as playing the same frequencies in the same order in the same phase relationship with each other at the same volumes with the same measured distortion, they by definition sound the same.
Doesn't matter if one is eight feet tall and capable of 900dB and the other is one square foot and can only play to 110dB. You do not hear a difference. You may see one and tell yourself you hear one though.

In theory....in reality, can two different speaker models accomplish what you said would be needed, highly unlikely I reckon.They don't.

I think they mean "IF they measured the same" they would sound different anyway. I have no idea but maybe 2 different speakers measured perfectly flat and their axis are the same they will still sound different they mean.Which speakers measure the same?
I had this experience with a bunch of the speakers I auditioned four years ago, particularly the group I zeroed in on for longer auditioning. I perceived differences, but they were not huge.I bet there's lots of well-engineered speakers that don't measure the same but it still wouldn't be easy to tell them apart in a blind test. You could but it wouldn't be as easy as some seem to think.
We did a phono stage shoot-out, speakers were Focal Electra 926 and Urei 809, two very different speakers from design point of view. There was a vote on which should be used for the shoot out and it was an exact tie, nine voted Urei and nine voted Focal so we tossed a coin to decide.
That intrigued me that there should be such an exact lack of consensus.
Later on after the testing people were swapping the speakers and amps and so on about and I mentally took a step back and had a listen and really there was not much difference at all between the sound of the two.
