    JBL 2360 Compression Driver?

    Hello!

    I have JBL 2360 with 2446 compression driver, playing together with 2x2226.
    My question is; has any of you any recommendations on other compression driver?
    Maybe Altec/GPA 288?

    TAD is to expensive...

    Had 6 of those horns in parallel in several locations when on assignment until 10 yrs ago.
    - 2440 with Radian 8 Ohm fram (later re-magged and with a 2441 fram)
    - 4001 (later 4002)
    - 4590P (later 4592 with ML LNC2 active X/O)

    Tell you what: you need the TAD, sorry. Preferably the 4002. In most instances, this is the inferior driver to the 4001, but on this horn, the main 4002 drawback does not materialize all that much. It is the subdued "chest" in singers (as in males and females) that the 4002 shows on many horns. The 2360 is solid/large enough to allow the advantage of the 4002 (better treble) to outweigh the leaner singing voices. Not that i am a TAD (or even generally a Be fan), but on that horn highly recommended.

    The GPA 288H could work, too. Again, typically inferior to the "G" version due to the exact same drawback/advantage mix as in the TADs, but here maybe OK to use the tangerine 'plug. Adaptors readily available, if you try it, please report back !

    Charah,

    Thanks for reply Ralph!

    So, rob a bank and get TADs.....

    I have adapters on its way in mail for mounting GPA on 2360.
    The 288 is interesting, and not so expensive, so maybe a way to go...? Alnico is tempting...?

    In the mather of sound I prefer Smooth over Crisp


    How about the two other GPA drivers, 390 and 399?

    I have no experience so every input is welcome!

    Wath is a tangerine plug?

    Best oks

    I put the 2450sl diaphragms on my 2446,s mounted on the 2360's . Smoother sounding and less fatiguing on the ears.

    Sure, definitely true and in fact a price-friendly alternative now that these large format 1st Gen neo drivers are so cheap. I have such frams in 2450SL and 2451H/J motors, but problem on 2360 is that the 2450SL is not 2" but only 1.5 -- means it's likely that for a 2360 use you need to get 4 divers and swap the aquaplas frams into 2445/46H/J or 2450H/J motors from the 2450SL.

    Never tried 390/399. Tangerine is the name of the Altec radial phase plug (see web or Henricksen papers or this site for details)

    Hi oks81,

    If using UHF driver for over 10lHz, then 2450sl, or Be diphragm would be possibe solution, but without UHF driver , I would suggest 2441 Aluminum diphragm, or even 2445 Ti (no ribs) diaphragm.
    Regards
    Ivica

    Thanks guys!

    Seems like nobody have tested Altec in 2360 so I will probably be on my own.

    Diaphragm:
    Googlegoogle...

    Know that Radian have the alu.
    Truextent have the be, but to expensive.

    I have no tweeter.

    With 2446 and standard titan I have the well known resonant 12kHz peak.


    So lets see:
    2450SL = D8R2450SL, titanium with aquaplas, sounds smooth. Reading this diaphragm sounds good.
    But no good over 10kHz....

    2441 = D16R2441, alu
    2445 = D16R2445, titan, no ribs.

    lots of number to remember

    Well, the 2360s are a bit long for yer avg audio nirvana, so the aircon install guys with those heavy-duty drills for doing 3 or 5 inch holes through 20cm concrete were happy to do a few more for me. Saved 45 cm of living room real-estate...

    The neighbours were scared a bit about 15 pounds of BMS a 100 feet above them, but after inviting them for a cup of Longjing were convinced full metal 2360T throats were up to the task. Pictured is driver model 4590P with the passive crossover taken inside for protection from Shanghai's elements (and pollution). The other side just came straight out of the 10th floor wall -- no A/C "balcony" there.

    I think he meant just putting the coated 2450SL diaphragm into a 2" exit driver - the 2450 driver (and the 2446 he mentioned) are 2" exit drivers, and the 2450 is neo magnet. They will take the 2450SL diaphragms just fine. But the 2450SL driver is the 1.5" exit neo magnet "pancake" driver. I have 2450 & 2450SL drivers, as well as 2450SL diaphragms. You can purchase 2450SL diaphragms without buying the motor assembly.

    Hi Jeff, the first part was understood on my end.
    However, i did not realize you can easily buy these individually without getting them as part of 2450SL drivers.
    Wasn't aware they were used outside the DSL studio monitors, hence my feeling they'd be tricky to get.
    Nice price, too !

    OK, I figured it was just a simple misunderstanding, you seem pretty well versed on these things.

    And some guys actually prefer the coated titanium to the more expensive Be diaphragms, especially for a little extra extension on the top - say a two way system.

    And yes, that is a very good price. Not sure how the shipping will impact the price to EU, but it's been mentioned that JBL is cutting the price on at least some things, maybe a EU distributor can get a similar price break.

    Yes, i agree they are very nice. I prefer the 16 Ohm SL over the 8 Ohm version. In fact, i find 16 Ohm sounds better most of the time in any compression driver (even HT371-16 tweeters better than -8). Haven't compared 2450SL to Be as i am looking for a second 476Be for at least two years now.
    ==> Do you have have access to the 476 fram by any chance?

    For the 2360 which have a mellow-ish treble tone, i would likely (have never tried it) prefer the TAD. Only guess, never tried. But given OKS has 2446 magnets already, and at the new low D16R2451SL price, a combination with the aquaplas fram seems very difficult to beat...
