I have four (well, three, a friend thought it was a good idea to put a tableleg through the cone on one of them) RCF 12" woofers lying around, salvaged from a huge Dynacord PA speaker. The model number is L12P50, but the closest I have found from RCF is L12P48. I have mailed RCF at several occasions but they will not answer.
I was wondering if any of you know of the L12P50 and might be able to give me some basic TS parameters for it. They're just lying here and i'd love to build something from them.
Some identification traits: Ridged paper cone, coated multiroll paper surround, alumniium dustcap, heavy die cast steel chassis, large motor (maybe 60 oz).
Thanks in advance.
