Have a look in here http://www.jblproservice.com/NAVIGATION/Studio%20Monitor%20Series.html at 4410 and 4412 and variants. They have your mid and top but not the 2235.
Just a starting point but it might help.

The 2235H is found in the 4430 network here:

Use the LF portion of that, combined with the MF and HF portions of this perhaps:

http://www.jblproservice.com/pdf/Network%20Schematics/4412A%20-RL%20Network.pdf

That will get you into the ballpark, some adjustment of the LF to MF crossover will most likely be needed as the 4430 crosses the 2235H as high as practical, around 1KHz. That is higher than the 4410's stated 900Hz. Could be OK, try it and see...

You might be better off building the 2235H's as subs and putting a 10" or 12" in the cabinet with the 104H and tweeter. In other words starting with a 4410 or 4412 and adding the big bottom from the 2235H's to taste... If it was me I'd start with 4410. (I have L110's modified with 104H-2 and 035Ti, utilizing a 4410A XO, and 4412A's. I find the vertical alignment easier to find space for. The 12" is good for a big room by itself, the 10 sounds best in a smaller room or with subs.)

thank you for the info i have been using this setup for about 10 years with some crossovers made by a authorized jbl dealer but only the mid and hi frequency are through the crossover.the 2235H is connected direct.this has worked very well but i had a tweeter die the other week and thought if there was a crossover available whilst i had them apart they could be changed .
i have also got a pair of 2402H 8ohm ring radiators and have thought about making a two way with the 2235H drivers but might be a bit harsh .
i have a krell KSA50 and recently crossed over to the dark side and purchased a SE 300B amp .
thank you again for your time .regards .steve.
