    Hello Harvey

    The link is a page on the site that gives you the scan sizes and a place to upload them.

    Thanks Rob

    Hi Don,

    On PDF page 11 photo caption, the gravesite marker is incorrectly located as Englewood instead of Inglewood as mentioned in the forum version of the photo. This is the Inglewood Park Cemetary, I grew up within 2 miles from there. Never realized JBL was buried there till I came upon thi9s site. Someday, we need to document exactly where that is and place a wreath or JBL Badge there on Sept. 29. Anyone up for that?

    Also, the forum document text also states date of passing was Sept. 24 instead of Sept. 29.

    Great Job, Don, will continue to check.

    Regards,

    Bart

    Pg. 34 of the pdf version, Last 3 sentences:


    "The fact that the Aquarius con-cept failed was unfortunate, but it was taken in stride. In fact, the introduction of the Aquarius series coincided with the introduction of the L100. That product emerge as the most successful loudspeaker ever produced by any manufac-turer in its day."

    The last sentence should read either "That product emerged..." or "That product would emerge..."

    Regards,

    Bart

    LE stands for WHAT?

    I enjoyed reading this article very much. I was amused at the mention of the origin of the “LE” model designation as Low Efficiency. I can imagine the marketing folks having heartburn over any reference to low efficiency on any product they are presenting in the market much less actually designating the whole product line as such. I can also imagine the engineer types equally unsatisfied with “Linear Efficiency”. "What the heck does that mean?... It references nothing related to the product or design". The LE designation stuck, after all, but I wonder how long this little debate lasted.

    David: from old catalog SC515 Dec. 1, 1963.

    JBL LINEAR EFFICIENCY LOUDSPEAKERS AND LOUDSPEAKER SYSTEMS

    JBL Linear-Efficiency transducers, the result of imaginative engineering and extensive research, are a unique combination of long linear cone travel and conversion efficiency. Lengthy cone excursion produces profound bass response in an acoustical enclosure of moderate dimensions. Relatively high efficiency for this type of speaker is the result of precision manufacture, advanced magnetic circuit design, and large voice coil diameter. The Linear-Efficiency speakers shown on the following pages are not normally interchangeable with the maximum efficiency speakers shown on the preceding pages of the catalog. Maximum efficiency speakers are designed for use in exponentially-tapered horn and bass reflex enclosures. Transducers in the Linear-Efficiency group deliver optimum performance when mounted in totally enclosed, or, at the option of the user, in some circumstances, other types of enclosures. Each group is capable of remarkably realistic music reproduction and will have its partisans among discerning listeners.

    Links broken?

    Second, there is a printable PDF version that can be downloaded by clicking on the link below. Be forewarned that this version is 14 MB in size, so I would suggest you only attempt to download it if you have broadband service.

    Unfortunately, neither of these links seem to be working. Is there another link I can use?
    My biggest fear is that, after I am dead, my kids will sell my audio equipment for what I told them I paid for it.
