    its up to you, but you might want to just buy them as cheap cores from him and find a shop to recone them yourself ... to be sure you get JBL parts done right.

    I wouldn't know if the seller is qualified to do the recone job himself, but JBL only sells those parts to authorized JBL service shops ...

    On another tangent - I own L200s rebuilt into 3ways (sort-of 4333 clones)
    with the 3133 crossovers, 2234 woofers (2235s but without the mass ring - its just what I had at the time) 2405 slots and 2420 1 inch drivers on 2397 smith horns - I REALLY like the sound of them for most anything - I suspect they're kind of like Cookys' but with just one woofer and the smaller horn driver.

    If you want to bring your 2441 drivers over, my smith horns are external and we could swap your drivers in, and you can have a listen to the 2234/2441-smiths/2405 combo and see what that 3-way sounds like.

    You may decide that's a nice mix and that it's all you need ...

    I'm in Fairfax, VA - not too far from you ...
    Just sent me a PM if you want to go further down that path ...

    Heather,

    We should definitely get together sometime. I will shoot you a PM. Once a listen to your system - I would get an idea of what the end results might sound like if I pursue the various options above.

    Thanks for the offer.

    You have Alnico version of the 2405 slot tweeter, and 2 inch mid horn 2441 (and smith horns!)
    instead of the original 2425 (with 2307 horn), but you are darned close if you want to go that route ...
    Which basically gets you my custom 4-way setup, except Im using 2441 drivers and alnico 2405s:

    JBL 2405H vs 2405??

    Hi all,

    (I'm still collecting parts).

    I wanted to find out if I should be looking for 2405H? or 2405? - I understand one is alino and the other ferrite - but am curious if people find one sounds better than the other?

    Thanks,
    D

    The 2405 is smaller in diameter and might be preferred because of that fact. The 2405 and 2405H technically sound the same. There is more variation model to model than ferrite versus alnico.

    Yikes - my mistake.
    I have an opportunity to purchase a piar of 2405 in really good condition but they are 16 ohms. Should I be looking for a pair that is 8ohms instead (i'm guessing this wil all depend eventually on the direction I head in). I will check when I go home, but I believe both pairs of 2441 that I own are 16ohms as well.

    Any thoughts on what I should be looking out for (16 vs 8).

    They are all the same impedance regardless of what is printed on the back. I've posted this numerous times along with the various diaphragms.

    075/2402, 076/2403, 2404, 077/2405

    Because this topic comes up ALL the time I finally asked Greg to put it to bed once and for all...

    All three diaphragm kits D8R075, D8R076, and D16R2405 use the same voice coil part number.

    Update: Trying to work out a deal on a pair of 2405 - hopefully I should have them by next week.

    I wanted to find out whether people would recommend going with a single 2245H woofer or dual 2235H woofer. I ask be cause substantial savings could be had buy purchasing 1 pair ov 2245s vs 2 pairs of 2235H. - Would I get similar performace?

    Any thoughts - I would imagin I would need these to cover from 30hz-250hz?

    2245H

    It's about a dB less efficient than dual 2235H's.

    Dual woofers can be very nice and if you want to go with them you might think about dual 2234H's in a 4435-type arrangement instead of dual 2235H's.

    - Respectfully suggest that you read 4313B(s)' thread called "9.0 cubic feet tuned to 30 Hz"

    - Then use the "advanced search" option ( using 4313B as the author ) / while inputting "2235H & 2245H" as the text that you wish to find .

    - You'll see that there's plenty of reading on this subject ( & yes, the 2245H usually comes out first with most LHF members ).

    >< cheers

    Update,

    I was successfully able to purchase a mint pair of 2405 (alinico) tweeters a fair price (should have them by Wednesday).

    In regards to the 2245H vs dual 2235, the main issue is the price difference. It appears that daul 2235 would cost me about $1000 (thats for 2 pairs).

    The 2245H (I had recently purchased one for $130 but needs to be refoamed <-the previous owner did not do the prettiest of jobs <-its fully functional, but not as neat as I would like).

    Reconed 2245H sell on e-bay for $275 all day <- these are not factory recones but "just as good" - I understand the with the 2235H aftermarket recone kits miss a ring or some sorts (that helps weigh down the cone). Is there such a concern with the 2245 after market kits?

    The thing is that I can simply buy another 2245H for $275 (only at your guys recommendation) and then I will collectively have a pair (for a total cost of $130+$275 = $405).

    Or I can hunt for a two pair of 2235H which would propbably cost close to $1000.

    What do you guys think? Should I go for a pair or 2245H with total cost of $405 or should I go for a two pairs of 2235H for $1000. Those who have experienced both - is $600 worth the difference?

    Thanks

    Do you really need dual 2235s - 4 of them?
    Why not do your mains with a single pair of 2235s and have sub with the 2245 for that low bottom range?
