Rush 1, be very careful about "identical" Morels. The point Mothra was making was that even finding Morels of the same model number may not mean a match. A blessing and a curse of Dunlavy's designs (Duntech and DAL) was the matching of drivers and tuning of crossovers with those drivers.
Depending on why you need to replace your Morels, it may be best to have them repaired if that's possible. For example, if the surrounds have failed, they can be replaced. But another caution there -- new surrounds must be the same density/weight as the originals if they are to be a sonic match. One who can do it correctly would be Miller Sound.
