Question Double woofer design - measure together or separately?

I need a little advice regarding designing a crossover for a double woofer speaker. I have done impedance and frequency response measurements for each driver. But do I need to treat the two woofers as one driver and wire them together as intended and run the measurements that way? And then use those results to model the crossover and Zobel circuit? I want to make sure that I approach this the right way.

Thanks.

Would a zoebel by any other name sound so sweet? Some sort of impedance compensation is often necessary, whether you call it a damped 2nd order filter or a first order with a zoebel is somewhat immaterial- I don't get too hung up on labels, crossovers are best viewed holistically rather than incrementally.

If you want both woofers to crossover at the same Frequency I would treat them together. That is if the combined resistance is not to high. If the total resistance turns out lower the size of the inductors needed in the crossover will be lower with less resistance and less loss.
Also component count will be lower.
