I'll reach out to Jim on Monday . . .
Can you provide details on the sub . . . age, plate amp specs/features and damage/issues with the cabinet?
It has to sonically match to the sub I purchased in March of this year
fwiw, this may help.
On the back of the sub, just above the power cord connection there should be the wording "DirectServo"
Just above this, in small print should be the model ( i.e. A370XLR3 )
