Puns, RB212, AX88 - crossover and delay

I've recently aquired 6x punisher V3's(Old Unstable rig). Im going to get 2x RB212 built and get a couple of AX88 v3 of my mate. all run using MC2 amps.

Can anyone help me out with a starting point for crossover point's and delays? I just need a starting point, I would be forever grateful!

Im hoping mr TimeBomb is still active on here and might pop up make some suggestions as he used to run these boxes together from what I can gather.

Puns will be run 40 - 90, then RB212 90 - ?

I've been looking at using Smaart, but i've got some learning to do before I can use it with any confidence

Thanks Tedski! It's the RB212 that is a bit of an enigma, but im keen to use them as they fit right on top of the puns.

I used to run the RB212s up to to 370Hz with a 24dB low pass and some out of band eq a bit higher up to take out a honk, the ax88 didnt really get to 180Hz more like 250Hz iirc, they couldnt keep up with the rb212s though.  Are those my old cabinets in the pic?
