Both in the book, "The JBL Story", which I am very much enjoying, and also in the 1975 JBL Home Speaker Catalog, to be found here at LH, there is mention of an "L400". Does anyone know what that was supposed have been? I'm very curious about this "L400", and would appreciate any information that can be shared with us. Thanks, very much, and God Bless!
