In the link l posted above the crossover used the AE15M and the De250, not the Jbl 2226 or the dna360
Looking at specifics the AE15M driver has similar sensitivity to the 2234 but the similarities end there .
(The 15M is an Altec416 on steroids. Excellent Low Xmax mid bass woofer )
The crossover schematic overall will be similar overall but the values adjusted for the 2234 woofer electro acoustic parameters and location of the seos 15 by Bill or Greg.
(If you plan to use a pair of 2234 per enclosure the helper 2234 has a simple low pass filter around 100-150 hertz
The bass reflex box tuning is over damped at around a low 26 hertz so when both woofers “add” together below 100 hertz you end up with a flat low end to 30 hertz @ 96 dB sensitivity).
You also have the displacement of dual 15 inch drivers reducing harmonic distortion at low frequencies
The high pass filter may also need adjustment for phase tracking and level matching
I would place the seos atop the main enclosure initially so you can adjust the location of the acoustic centre
You will also have the option of easily changing out the seos if you want to trial other horns and drivers. This way you can progress over time with changes to the Hf horn/ driver combo
