I have a wonderful pair of JBL 4341 speakers but I need the full crossovers and Lpads for them. Does any one know what I can use as a substitute for now and them I will change them when I find a pair of the original ones. Any help will be appreciated. The drivers are 2231A, 2405 (or 077 drivers, I have both pairs) , 2420, and the 2121 (which are reconed with original jbl 2121 cones) . Cabinets are close to mint with grills. I have all the drivers but just need the crossovers to finish the project. thanks for looking
