I picked up a sub cabinet with a JBL 2226H which seems to have been stored too long as the spider has sagged inward statically offsetting the voice coil, cone and pleated surrounds. The spider is not level but also offset inward towards the magnet.
Does anyone know of an appropriate way short of a spider replacement or recone to reset the spider or surround - I'm thinking heat (oven? hair dryer, heat gun), solvents, exercise via sine waves, static offset in other direction using spacers from frame to cone, storage with cone facing down, etc?
There must be a way to fix this without redoing the whole driver.
