Hi Michael,

I would just apply glue to the edge of the crack; it will seep in to where it is needed. After it begins to tack up (couple of minutes, you can gently push from both sides simultaneously with your fingers to make sure the fibers are mended back together. When dry there should only be a slightly dark line to remind you of the crack.

You'll have to experiment to see what method of baffling these drivers works best for you. I recommend front horn loading, but then I'm a horn guy. They probably have a resonant frequency of 60 or 70Hz., which gives them a nice bass snap in an open baffle. They will extend up very high, as they were often used full range in the organ cabinets, but will sound pretty rough for hi fi use above 2kHz. I'd cross them over to mid drivers at 1kHz. or below.
