Hi Steve,
As I have understood You have:
- 4x 2225 (or 2235) drivers,
- 2x 2470 drivers,
- 2x 2307 horns,
- 2x 2308 lenses,
- 2x 2405 drivers.
My be care opening of the bass drivers, and cleaning and re-gluing would be enough,
but work on the network has not to be " depreciated ", and careful measurements too.
Regards Ivica
