Question on 1960's Shure PA Column Speakers

    Hi, I just bought 2 old Shure PA columns, you know, the heavy 5
    footers. I was told they are from the 1960's. They look older than the
    Shure columns i've seen on eBay lately. Mine do not have a silver line
    running down the middle of them from top to bottom.

    They are model SR103, and the plate has two wattages listed, 78 and
    34. Was that for when there were more than two columns wired together?

    Anyway, my question is... what exactly do I have here? I've spent a
    day on Google and haven't found much, except when I searched on
    "VocalMaster". Mine do not say VocalMaster on the front or on the
    plate, though. And it seems like people rip VocalMaster PA systems
    anyway.

    Any info you can give me would help. And a manual or web address with
    similiar info would be awesome. Is there any way to determine their
    age?

    My plan, unless they have great value, is to add a 1/4 plug, and use
    them with a head for my Fender Strat. But I don't want to mess with
    them if they are rare or something, not because of value but because I
    have a thing about keeping rare, vintage things in their original
    state.

    Thanks,

    - D Man

    Sorry, I remember them, but no details. Here's a search of Vocalmaster
    from www.shure.com:

    Here's some info from shure.com:

    I have no idea if these things are rare/valuable/desirable. If I had
    to guess, I'd guess they're not.

    BTW, based on what I found at the above URLs and the data sheet, you
    could just attach a female 1/4" input to a speaker cable, then attach
    the wire ends of the cable to the inputs on the speaker cabinet. No
    need to add a 1/4" input to the speaker cabinet. See page 4 of the
    data sheet for more info.

    You have Shure Vocal Thrashers .. the ultimate piano lounge/cover bar
    band (that wore spandex and polyester uniforms) PA .. not even
    suitable for a rehearsal system for any serious band!! The frequency
    response is a very ratty & distorted mid range only!

    If these are identical guts to the old Vocalmaster columns, they should have
    one 10" speaker and three 8" I think... is that right?
    If so, they are also wired in series so each cabinet is 24 ohms total. You
    were supposed to run up to 4 of them in paralllel, so you had 6 ohms when
    all were used.
    VERY ineffiecient speakers. Also there was a rear vent to cancell out the
    very low end.
    I took a pair once and made them much better by removing one of the 8"
    speakers and adding a horn mid with xover. Then, I sealed the rear vent. I
    wired the pot to the horn only for control of that. the open area around
    the horn became a front port for the low end...
    It actually improved it 100%!, plus the total impedance became about 4ohms
    when done (I kept the 10", one of the 8", so those were 4ohms in parallel,
    and the horn with a xover was pretty high impedance.

    Response to Shure columns, models SR102/3

    Greetings,
    With regards to your questions about your Shure columns, what you have are GEMS!
    I ran across mine at a junk shop, got two for $100 each. I have regretted ever since not snagging two more that were available too.
    Best performance is achieved via a 72-volt configuration (less line-feed resistance over long runs), but these babies are phenomenal for just about any situation.
    I've used them for indoor and outdoor events for nearly 10 years now, and they perform just as cleanly as the day they came home to live with me.
    You can download (as PDF) the spec. sheet for both at:
    http://shure.com/stellent/groups/public/@gms_gmi_web_ug/documents/web_resource/us_pro_sr102_ug.pdf
    Enjoy your acquisition. Ya done good!
