    best horn for 2425?

    hello,

    i have a pair of the 2425j drivers an the 2370 horns. i donīt like the sound of the horns...is there an better sounding alternative?
    the crossover frequenzy must not be so low.
    does it work with the nice and small rcf H100 ?
    the driver has to work with a 10" midbass.

    thanks, alec

    What don't you like about them??? There several combinations you could use but it's hard to say without some idea of what you are looking for. IMHO the 2344 is a tuff horn to beat. Can go to 1K. The standard 4 way crossed to a 10" mid @ 1.2k add a 2307 and 2308 Lense but you will probably want a 2405 on top.

    i want a small, 2way mid high top with a 10" midbass. it mustn run standalone, i will use it with a sub. the 1" has to run from ~1,2k to the end. the 2370 ist to big for my small satellite, thats the reason why i m looking for an 60/90 alternative.

    regards, alec

    Try the new waveguides

    http://www.jblpro.com/ae/pdf/PT_WaveGuide.pdf

    I'll try the 100x100 Version instead of the 2344 in near future.

    Wink new waveguides

    Are these new waveguides available to purchase as separate components? I am looking for horns to build a system for a friend on the order of a 4430 type system. I already have some old LE-85s a 2440 driver, a pair of 2334s, 4 LX-5 xovers, etc.
    Thanks

    Hi Alec

    Are you using a 2425 or 2426?

    I just got a couple of the new JBL OASR 1" horns to run with my 2426 drivers in the rear speakers of my HT. Fronts and Centre will be 2451 with 2332.

    The OASR is a 4th (I think) generation conical horn with 85x85 pattern. I do not have much info about it, except that it is used in the SRX and Marquis series currently.

    From what I can figure out it seems to have been introduced during 2002 or 2003 so it should be based upon then new equations, being used for among others the waveguides mentioned above.

    It is a CD horn, which makes it a little different to the, by now, rather old 2370s. The 2370 is a Bi-Radial design.

    I have no idea of how they sound for home use yet. I have heard the SRX, and they do sound decent to me. Anybody else with input on this horn paired with the 2426 driver?? Giskard, Mr. Widget or somebody else?

    It is very compact and rather shallow which suits me perfectly for a small 2-way rear HT speaker. I'm going to flank it with two 8" drivers, one on each side.

    My conclusion was the same as yours; the 2370s are too big for what it delivers for home use. The newer designs seem to be better suited for home use although the 2370 still do deliver the goods in professional applications. If I were designing a stage monitor for live performance I would seriously consider the 2370. But then gain, I’m not. J

    Please se; http://www.jblpro.com/pub/mi/srx_chrt.pdf

    The only difference between 2425 and 2426 seems to be the mounting options. The 26 have a threaded throat under the adapter ring where the 25 only offer flange mounting. The OASR is a thread-mounted horn

    If you do have 2426's or know of how to make an adapter to threads I can post some measurements of the OASR/2426 during the weekend if you are interested.. Please advise.

    Best regards

    Hi Alec

    I will try to take some pictures tonight and post them for you.

    And yes, the OASR is does not have the flage but a screw-on neck with threads. I don't know if there are adapters that go from flange to thread. The other way arround is easy.

    You could possibly find somebody in you area that repairs JBL and ask if they would be willing to swap the houses if they have 2426s mounted on a flange type horn, where they do not need the treaded neck. 2426 uses an adapter ring to mount to horns with flange mounting. You just unscrew the adapter and there you have the treads.

    You will see from the pictures later how it works.

    Best regards

    Hi Alec

    Here are some pictures of the horn and the 2426 drivers. The other driver on the pictures is an 8" driver just for comparison in size.















    Best regards

    Hey Rob how do those OASR's sound?? Do you have to compensate them?? If so how?? Any frequency response curves on the horn??

    Thanks Rob

    The network of the 4722x looks strange.

    I do not understand that kind of compensation
