Mspanl, Well, you've certainly set out a bit of a problem. Here goes: You could try some of the stock replacement drivers from Part Express or MCM electronics. Most are inexpensive OEM types the MIGHT work (but probably not that well)..... Since you say that the cabinets are the best part of the system perhaps you might consider looking for a DIY design that would use the cabinets but replace the existing drivers and crossovers. (This is WAY more $$$) Other driver suppliers that have inexpensive drivers are Zalytron and Madisound. Both are on the web and have very good catalogs and reputations among the DIY community.
