    4345 clones. Let the games begin!

    Hi gals and guys.

    I'v been requesting advice from you regarding JBL products. It has led me to start a 4345 clone project. I will be needing even more valuable advice in the future. So far I scored a pair of alnico 2405's on ebay and just made a deal with a fellow forumer for a pair of 2245's. Nice budget sucker these JBL's are. Oh well after all quality costs. Anyway my plan is to get a professional carpenter build me the cabs, as I know a company that is nothing but quality and doesn't cost a fortune.

    On the lower midrange I plan to use NOS 2123's.
    That leaves me searching for a pair of midrange drivers, horns and 2308 lenses of course. It seems I'll be searching mainly for 2425's and 2440's and apropriate horns.

    So anyway I need to repair my budget and will be sourcing more drivers soon. The quicker I hear these babies play the sooner my face will start looking banana like.

    Cheers, Maciek.

    Maciek,

    Good decision.

    If I could make one recommendation, I would suggest you go with the 2441 (or 2445) and 2311 horn in lieu of the 2307+2425. To top it off, finish them off with the latest itteration of Giskard's 3155 Charged Coupled Crossovers.

    The 2307+2425 is no slouch - its just that....for some strange reason...the 2" driver is more pleasing to my ears. Also bi-amp - I can tell the 2245H enjoys power.

    All in all - I would say make your 4345 Clones equivalent to ones built by Giskard a few months back.

    Goodluck.

    Dhar

    Dhar nailed it. If I were to go through the trouble of cloning 4145's I'd go all the way. 4341b's version is the ultimate (until someone uses beryllium dias and gets the network nailed). Also consider the folded "mini hartsfeld" lenses instead of the 2308 if you can find a pair. They are accoustically equivalent, but much more attractive and made out of metal.

    I know what a 4341 is but what is special about a 4341b??? Just wondering...
    Well why not it's just one more pair...
    4340's and 250ti's what an odd pair...

    I think he meant that username "4313b"'s were the ultimate. Just a typo. 4313B built some quasi 4345s with 2" compression drivers and a CC network that were pretty sweet.

    Now I'm convinced to the 2445/2311 combo as it seems the driver is better suited for Giskards 3155cc also availible quite a bit easier and cheaper same for diaphragms so can't go bad with that one. As for the lenses I highly aesthetically prefer the 2308. Might try to make some replicas of my own in any sort of exotic material ?wood, carbon fiber, chinese plastic?

    When it comes to power I like listening to music at very moderate levels. Loudness just distracts from the essence of music. I will be most likely trying to achieve a great tonal balance rather than extreme levels of hearing loss.

    So now it seems I have most the basic info figured out.

    Dhar, you used the 2122 while I plan on using the 2123. Did you perform any mods to accomodate?

    So Amnes...

    Does this mean you passed on the XPL200s?

    Though I'm fond of the XPLs, the 4345 is definitely the way to go.

    Yup, just a typo. my brain said type 4313B, but my fingers had their own plans.

    Air coil won't do

    See the thread "Enclosure Size for 2215H" in the "Lansing Product Technical Help" Forum for considerations about the series coil in the crossover. You will need a coil with a core.
