    D-175 / 175 / LE75 / LE175 serial numbers Part 6: The LE75

    The LE75 was introduced around 1960. It did not replace the original 175 which continued to be produced.
    The LE75 was labeled in two forms with discontinuous numbering:
    Early form was a decal with the model number and impedance typewritten, but a printed (or ink stamped?) serial number, same decal as on some crossovers and speaker systems of the same vintage.
    Note that the decal says "signature sound" not "signature speaker".
    All of these that I’ve seen have the script “L” pressed into the red wax seals.
    LE75 serial number 3726
    LE75 serial number 3736
    LE75 serial number 3779


    Later form was a gold foilcal with printed model number and stamped serial number.
    This form starts with the script “L” pressed into the red wax seals, but by the end of the series have “JBL” pressed into the seals
    LE75 serial number 1101
    LE75 serial number 1105
    LE75 serial number 1277

    Not sure if this helps you with your database but it's an interesting pair and all the serial numbers are listed

    http://cgi.ebay.com/ws/eBayISAPI.dll...m=260009912103




    JBL Custom ALNICO Speaker PAIR LE15A/LE85/L91/LX5

    BEAUTIFUL pair of original James B Lansing Custom made speakers cabinets. Each custom cabinet contains a vintage JBL ALNICO LE15A 15" Linear Efficiency woofer, LE85 1" ALNICO compression driver, H91 Trumpet Horn, L91 Slant Plate Acoustic Lens, and a LX5 500Hz crossover. Each set of components is enclosed in custom made inner wood casements which than slide into original custom made outer cabinets.

    These custom made Lansing cabinets have had only ONE owner who ALWAYS kept them in a controled envirorment. Original owner was a hardcore audiophile and had these custom built sparing no expense to create an amazing speaker system.

    All the components are in SUPER CLEAN condition.

    Please follow link for a FULL description, and PHOTOS

    Nice stuff Magus!
    It does help to have a set of component serial numbers for an entire original speaker system (S7 system in this case).
    I include the serial numbers here because eventually the auction will go off-line:

    LE15A serial number 9023 and 9029
    LE85's serial number 6182 and 6266
    H91 serial number 12507 and 12530
    L91 serial number 13122 and 13119
    LX5 serial number 11549 and 11559

    The LX5 serial numbers fall between others I've seen that are believed to be from 1966 (10745 and 12798). So most likely all of these components are from 1966.

    Thanks for your contribution Magus!

    C38 cabinets with S12 systems on ebay

    Seller claims these are from 1961

    C38 cabinet serial number 33540 contains:
    LE14A serial number 3428
    LE20 serial number 6291
    LX8 serial number 2116

    C38 cabinet serial number 33541 contains:
    LE14A serial number 3429
    LE20 serial number 6293
    LX8 serial number 2113

    in auction:
    http://cgi.ebay.com/ws/eBayISAPI.dll...ayphotohosting

    from auction description:
    These are the less common C38's from 1961 with the veneer wood and the metal feet, they are loaded with LE14a woofers and LE20 tweeters with LX8 crossovers...they are most likely entirely original and honestly show no signs of use or wear at all they are sometimes referred to as the "Baron".
    These speakers are in amazing condition inside and out, they are from 1961 and appear to be entirely original and in nearly MINT condition!! please see picture collages below, they are very large and sound good although i did not crank them up because i only had modern equipment to test them with...
    the cloth grilles have no rips or snags or pulls, the speakers themselves are amazingly flawless (no cracks on surrounds, no marks on the beautiful white surfaces at all..... the backs of them are also like new. (in the 2nd pic the one tweeter looks dirty on the back but it is not...that just shows how bad my camera is).
    the cabinets are also in nearly perfect condition with NO damage except for what is noted on the 3rd pic which is a tiny surface nick and scratch and some rub marks from something white, the other one is basically flawless..... the feet are also in amazing condition and the wood where they attach is fine (they sometimes would weaken there over the years) the "rubmarks may come off easily...i did NOT clean them before i took the pics....this is just how amazing they have stayed after 45 years!
    I DID NOT CLEAN THEM FOR THE PICTURES..... the cabinets are a little dusty but i did not want to make them look better than they are.... no need to really, they speak for themselves.
    serial numbers on the cabinets are consecutive also and the one cab has the envelope attached to the back for the papers (i do not have the papers though).
    They are huge, they are heavy..... shipping is going to be alot (2 packages with feet removed and each speaker wrapped inside a new blanket and shipped from a ups dropoff center, these are way too big for me to package here so shipping may be in excess of $150 i am guessing, any difference will be returned to high bidder.
    You will NOT be dissappointed in these and may not ever find another pair in this kind of condition either, i know i was amazed when i aquired them and have been dealing in vintage audio equipment for over 10 years. good luck on these if You are bidding...the reserve is very modest for these speakers as well.

    S8R in custom cabinets on ebay

    Seller claims this pair of S8R systems are from 1974 and he is the original owner. (I don't think the S8R system included the 077 until the 1979 S8R-2 system that also came with LE15-H woofers.)


    components:

    LE15A serial numbers unknown
    PR15 serial numbers unknown
    375 serial number 21670 and 21894
    HL93 serial numbers unknown
    LX5 serial number 30760 and 30761
    077 serial number 30924 and 40156
    N7000 serial numbers unknown

    in ebay auction:
    http://cgi.ebay.com/ws/eBayISAPI.dll...ayphotohosting

    from auction description:
    ALL speakers are in PERFECT WORKING condition!
    These have always been in my climate controlled home (i.e. never stored and are from a smoke-free and pet-free home.
    Each cabinet weighs approximately 150 lbs. and is 45” wide x 19” deep x 38” tall. – My friends often refer to these as "THE BIG KAHUNAS". The midrange dispersion lens is easily removable – as can be seen in the photo with the grill cloth removed. The lower section of the cabinet – where the bass & passive radiator are present – is air tight for proper performance. The voice coils are flat ribbon wire hand wound to get maximum density and capacity. The Alnico V magnets used in ALL the drivers produced 250% more energy than a comparable ferrite magnet. All components are precisely machined to achieve exacting sound reproduction.
    The serial numbers are as follows:
    Ø2-(375) midrange drivers are: 21670 & 21894
    Ø2-LX5 cross over networks: 30760 & 30761
    Ø2-N7000 cross over networks no serial numbers visible on outside
    Ø2-077 high frequency drivers: 40156 & 30924
    Getting into each lower cabinet where the LE15A bass speaker & PR15 passive radiators are located is difficult. I cannot disassemble the lower airtight cabinet without breaking seals. Each cabinet has the airtight back secured in position with 42-2" wood screws. The seam joints on the back - although a tight fit - were sealed with silicone rubber. The bass and passive radiator in each cabinet are front loaded, mounted with 8 machine screws & nuts supplied by JBL and sealed to the front baffle with the circular silicone gasket seal also supplied by JBL. I will not break these seals simply to get the serial numbers.
    For years from it’s beginning through the 1970’s, JBL built what the most knowledgeable audiophiles would consider the “Rolls Royce” of speakers. JBL was used in the finest recording studios because of the truly sound reproduction. They were – and still are – some of the most efficient speakers built.
    These systems – built in 1974 – are still used as beautiful pieces of furniture. The cabinets are finished in gloss black walnut stain and are on casters. The cabinets are “handed”, that is – mirror images of each other.
    As the original owner of these, I’m selling them simply to downsize and give someone else the opportunity to enjoy music at it’s best. They have served me well and I would put them up against any other similar size system for performance.

    Hello All- not sure if this is any help, but I had done a quick inventory (serial #s, but don't know any dates) recently for insurance and to-do-list purposes, but I can't seem to find a way to fly in the Excel spreadsheet format. Any advice, other than re-typing the whole lot?



    Thanks,

    je

    Thanks for lots of info Fred!
    Are the 4333A components original to the 4333A cabinets you listed?
    It would be extra helpful if you could match any of your components to their original cabinet serial numbers if you know that info.

    Thanks for your input!

    As far as I can tell, all but one of the woofers were original to the 4333s. These were in Clive Davis' office/listening room at Arista Records- my company removed them at some point for upgrades, so I don't know the whole history.

    The L100 components listed are piecemeal from various sources (in fact, I think they're not exact spec, right? The woofers are a later model).

    Thanks,

    je

    C31 system in ebay auction

    C31 system in factory cabinet (Jim Lansing decal) ebay auction:

    130B serial number 308140 (two woofers, both with same serial number)
    175 serial number not listed
    1217-1290 horn serial number 306-121
    N1200 serial number 306147

    This system would have been manufactured in August of 1953 by my current interpretation of the date-code serial numbers on these components/

    from auction description:
    you are bidding on a extremely rare JBL JIM LANCING speaker. this is a SINGLE unit. features 2 - 15" woofers, 32 ohms, matching serial numbers. the cabinet is in fantastic shape. this speaker is huge and is very heavy. this is the one only only time i prefer local pick up. I WILL NOT PACK OR SHIP THIS ITEM. if you are not in the vancouver, canada area and you still want to buy this JBL, you MUST ARRANGE YOUR OWN PICK UP.
    however if you only want the components, those i will ship.
    Q:Hi Phatstereo, Can you please tell me the serial numbers on the hor, driver and upper woofer in this rare vintage speaker? Thanks and good luck with your auction! Glen
    A:hello, the serial # of the horn is 306-121, model 127-1290. the serial # of the 2 woofers are identical 308140. you cannot get a better match than that. thanks, phats
