Layne,About time you came over and visited the Pi speaker forum. You will find a lot of useful knowledge here. This is where I started when I found the site during a google for "2205's".
Is your fullranger going to have a tweeter section on it??? Wayne can help you out on the crossover section if you give your requirements you need: ie: 12" or 15" bottome end crossover to FR with tweeter covering top end. Something like that with the driver details included helps out a lot.
I think the 4 pi-pro cabinets are the ones you are wanting. There are several 4 Pi systems, so it is necessary to select one. For the 2226 or equivalent, the "pro" version 4 pi is what you want.
