From Availability of JBL Consumer Transducers for DIY:
I try any used JBL driver that I can get my hands on, but would appreciate your comments on which products are useable for home use, or not. Only currently available drivers are considered. Some of these drivers have their graphs published in Tansducer information, but others not. Some are really old designs, but maybe wort buying new anyways?JBL Pro has continued to produce and sell a number of raw drivers. Many are very suitable for home use, but many others are definitely best used in PA systems.
