    4502 enclosures - 3420 Control Monitors

    Here is the info on the two monitors I bought in Philly Feb 2006. The seller said he'd had them 13 years and bought them from his brother's friend - from NJ.
    They are 2-way systems - but I am adding 2405 drivers to extended the frequency response and improve the sound.
    There were no grills and nothing that said "Model 3420" but I gather thats what they are. The cabinets are plywood with walnut veneer. I didn't get the serial number of the horns (Model 2307), just the driver info.

    ======= box 1 ============

    4502 Enclosure s/n 11275
    3110 Crossover s/n 1478
    2215 15" woofer s/n 2180
    2420 MF driver s/n 1731
    2405 HF driver s/n 62198 (new to unit)

    ======= box 2 ============

    4502 Enclosure s/n 11165
    3110 Crossover s/n 1326
    2215 15" woofer s/n 1566
    2420 MF driver s/n 2193
    2405 HF driver s/n 61269 (new to unit)
    ========================


    There are also a pair of plastic lenses that came with them,
    2308 Lens s/n 10085
    2308 Lens s/n 10582
    They weren't mounted when I got them and I'm not sure if they're original

    Once I get the slot tweeters installed and update the crossovers,
    I hope to put them on top of the shelves where the L36s are now.
    ========================

    I hope this helps the list .
    Thanks for all the info you provide US!!
    I would NEVER have dreamed of or even started such a project without all the legacy info on this site!

    Hi Heather,

    thanks for your data....the list grows ...

    seems that the model is the 4325......the 4320 uses a crossover with 800hz, the 4325 uses 1khz. It maybe from the years 1970 to 1973......and YES, the lens 2308 (in this times named HL91) need to be mounted.
    A wonderful speaker btw.

    i'd love to know when my system was assembled. unfortunately i have no real knowledge of it's provenance other than i believe i acquired it in it's unusual original condition/configuration.

    i have the serials from my 375's (see avatar for one of them) but would have to open the cabinets again to check the 150-4C numbers.

    i suspect my system was built circa 1960.

    Hi Harkness,

    try to find out all driver numbers....then we will see.
    The list has now 302 entries with different speakers, maybe we can find a numbers run.

    here are some numbers from my Harkness system (as obtained).

    375 no.1 - 2885
    375 no.2 - 2053
    150-4C - 22725 - pretty certain from a pic i took (hard to read though)
    150-4C - ????? unable to obtain at this time.
    N400 no.1 - 1376
    N400 no.2 - 1457

    the system came with H5041 90 degree horns as the 375's were mounted in the mouth of the bass horn. no serials on those horns though.

    A recent addition to the collection...

    Metregon C45 Serial #457 (Dark Walnut?) (I am the 3rd owner)
    Series 205 (that looks like it's new)
    130A's (never been removed so no numbers)
    275 (serial #539 one side (only) has been opened)
    N600s (1422 & 1425) these have been bypassed with
    N-800-Ds (which have no serial numbers, if so... I'm needing info on where the #'s are located)
    Made in 1960 (just a guess but garnered from available paperwork from this forum. Thank You

    gotcha

    Hi Glen,

    like me you are lurkin and fishing ebay for numbers....
    this works very well and shows also some fraudly intensions of some scammers. See my thread in General.....

    With more entries we know more about the systems and numbers.
    So we can see that the Olympus start with 5 digits and 4xxxxx.....
    well knowing that there were built about 2500.

    Thanks

    HP

    PS: I activated the automatic search function for " JBL serial numbers" and a lot of systems came up.

    Serial number 1291 & 1288
    Inside the Xover's
    Model N700P (Both)
