I would guess no. More effort will be put into voicing the speaker than the mathematics of the xover design for a given box and drivers would suggest. Since each of the three designers are just like the rest of us with different tastes, perceptions and prejudices, the final product will most likely reflect that. That's why, IMO, different products sound different.
Speaker Design
If you take three speaker designers, say Dennis Murphy, Joseph D'Appolito, and Albert Von Schweikert and give them the same cabinet and drivers and tell them to design the crossover.
The question is will the three speakers sound the same?
How do you think they would sound differently and in what areas would they sound alike?
