Old speakers the surrounds on the driver need inspection ,
and for sure the Xover needs to be upgraded. I have been upgrading crossovers for years and stock ones are on average in quality or below at best . And capacitors-dry out over time especially over15 years , and higher quality parts make the whole speaker much better sounding.
