I recently acquired some EAW SM222 cabs all are the J versions. I purchased 4 initially and found another 6 later but two of the 6 do not have woofers in them. The model number on the woofer is RCF L12P-400. I have searched high and low before posting and even emailed RCF to see if there was a cross reference to this model. They stated that they did not support the EAW drivers anymore. I was thinking of getting the Dayton Audio DATS system and getting measurements and and finding something that models close but I don't know how accurate those measurements will be due to the age of these drivers. Any help would be appreciated.
