Crossovers for JBL 4412A

[vmscbe1974]

Dear members
Off late I feel I should go for a replacement of my JBL 4412A speaker crossovers . I feel the sound quality bit low compared to the initial purchase period , is it advisable to go for a replacement or leave it aside . The overall output for low,mid and high range have come down. I purchased few years before as second hand unit only so unknown history. If the crossovers need to be changed how do I procure it and from where ? Thanks and regards

Not from "A" model, but if I'm reading the 4412 manual correctly, there are no electrolytic caps. Not sure you need new XO parts if that's right. Perhaps try to do the easy stuff first--disconnect, clean, reconnect. Try other amp to verify speaker issue, etc first. It's easy to lose years w/o re-making connections and it can matter.
