OK, presuming the folowing.

Sub, PD186 geting 900w or so (available but controlled)
So what would you give the XB in ESP-18BPH power wise?
Then what would you give the 12 mid and 1" top.
Would 500w of kick be enough?

just seen this old thread, so i thought i would re start it........

this is kind of a trick question, the pd is 700w with a sensitivity of 97db at 1w1m, the xb is 1000w with a sensitivity of 99db 1w1m......

so if the pd was getting 700w then the xb would need to be given 676w to have the same output as the pd.......

if the pd was getting 900w controlled, then the xb would need 883w to be putting out the same power.... if my maths are right......
the sensitivity plays a big part in levelling out different drivers.

for example driver a 1000w with 99db 1w1m, driver b 1000w with 97db 1w1m, driver a would be louder...... at the same level of input...

And then you get to the gig, and try to give the subs a good trashing.

Peace and goodwill to all speaker builders
