Good morning, I ask you for help to restore to the best of JBL K2, unfortunately they have decentralized 435BE drivers and in my opinion they are useless, even the diaphragms are badly put only one diaphragm is recoverable, the other is gone. I am thinking of replacing Driver and Diaphragm with a new pair but being the 435Be not found I have to settle for mounting either 435Al-1 or alternatively 2435HPL. I ask if replacement is possible, do they mount on the horn?
