2 inches!
18 inch bell on the 52j for a more compact and "boomier" sound. The 56j has basically an inch more of bell flare added around the diameter of the bell (20" bell). I can't comment on the sound differences, as I've only played the 52j, but there is quite a bit on the subject in the archives.
