Ah, but that’s not suffering. It's a feature only present (to this extent) in 4x12" constructions.
And if one of the Kemper/Celestion speakers behaves like model x it will interact with other speakers behaving like model x the same way.
It seems that the 4x12" lovers can not only have the cake now but eat it, too (when slamming 4 of these speakers in a cab, that is).
That was my thought too...
Hopefully it should be no different to putting a quad of v30s, or greenbacks or lynchbacks or evhs or whatevers into your current cabinet...if each speaker receives individual dsp correction - the interactions should be 'a 4x12' experience.
