Advice sort: I have just pulled my La Scalas out of storage after something like 20 years. They were purchased brand new back in the early '80s and have had a very easy life with minimal use. I felt it advisable to check the 15" bass drivers. With the inspection I feel the cone has, over time, deteriorated a little in appearance. I'm wondering if I might be best to apply a coat of something like Bostic EVA over the face to prevent further loss of the original surface. This product has been used as a glue and also, thinned a little for application, used for weather proofing cone drivers.
The crossovers are type AL. They appear to be in good condition with no sign of swelling or leaking of any kind from the components. What checks can I perform on these? I'm looking forward to running my La Scalas up again and shall do so cautiously. I welcome your advice - thank you - Greg .au
