Gauss Drivers,

I am looking for datasheet and information on Gauss drivers?
I recover an old Gauss 5840 for free. I would like to recone it because the driver is not working.
I was told that this driver can be recone in a sub-bass 4583.
I know nothing about the 2 drivers.
Can you help me locate datasheet and parameters for the Gauss range of drivers?
