its an original 3HP motor (before the threaded gap plates)with a 10" frame. that motor was designed and in production for the older eclipse Ti drivers. It was also used for smaller OEM orders but im not sure which ones - could be dozens. I'm not sure exactly who/m this driver was built for or if more were made.
The black glue on the spider to vc indicants that it was not made (or reconed) recently at least by TC Sounds. TC uses grey glue now.
