    Yeah, I got hold of the seller out there in California a while back. They're local pickup only/cash only. He didn't want to talk about shipping at all.

All in my living room. My favorite is still the 2420/2344 combination. I sold the rest except for the 2307/2308 for nostalgic reasons. I play active and have the M553 active crossover set for CD compensation, which does not fully compensate, for the 2344 dropoff but does it good enough in my setup.
    Interesting. I always enjoyed my 2344/2425H combo in the 4430. But I never really beat the unholy crap out of them like some folks do who complain about their strident howling.

    I'm kind of convinced that the 2435 only works well on the Array horn.

    I have yet to try the 2450SL on the PTH1010 (I'll be trying the 476Be as that is all I have on hand at present).

    I ran that combo for about six months in my living room. Pretty nasty actually.

    I'm afraid it's not good news. It appears the horn is not available. It has been over a year since we have had it in stock.
    I apologize for not getting in touch sooner.



    It works out well, I didn't have time for it anyway.

    These horns got sold, and he was asking $150 per piece- that's drivers and horns, $600 total. Still reasonable but not the screaming deal it looked like. He still has the drivers and is asking $160 per.

    That has also been my experience (H9800). When put horizontally it is also quite good, but the directivity tends to collapse more rapidely above 10khz (due to the poor phasing plug of the 2435).
    The array horn is really close to a 2344...

    Hello 4313B

    I am pretty happy with it on the PTH1010. Shame you can't get them anymore. Takes a couple of notch filters and you have to cross them high so great for a 3 way not so good as a two way. That was always the problem with any of the PT waveguides, high crossover point. Granted not as good as the Array but still quite listen-able.

    Hello Pos
    Yes it is you can drop them right in the same baffle cut out.

    These JBL PT waveguides all seem good down to around 1300 Hz. I don't see how one can use them with a fifteen the way JBL used the 2344 with the 2235.

    Have either of you played around with terminating the sides using a round over (~ 2.6 inches for 1300 Hz for example)?

    I'm not sure of the exact reason JBL did away with the 100 x 100 guides. Probably not enough call for them in SR.

    Yeah, I really don't know which came first, the 435Be on the H9800 or the 2435 on a waveguide. Doug wasn't real keen on discussing the phasing plug issue and I didn't care enough to press it. We basically left the discussion at "it works fine on some horns/waveguides and not others".

    I was toying with the idea of using the PT waveguide as the throat of a big horn, like the two-part assembly of some of the recent JBL consumer biradials. The rectangular 100x100 would probably be the best candidate for this, as it is really short and does not enforce much "shape" on the veritcal plan (contrary to the rectangular 90x50).
    The big horn could be a simple conical or radial, and its geometry would not be really critical: the "throat" (the PT waveguide) would handle the critical part, and the rest of the big horn would only serve to maintain directivity lower.

    While not really germane to where the thread has gone, the 2425 drivers where used with a PAS 15" to create the coax that was the core of the Urei "B" series studio monitors. So I'd say they can be fully suitable for HiFi uses.

    The 2425 was used in the DD55000 Everest along with an E145 variant and a 2405.

    Hi Steve,

    One possible solution is to recone 2225 with C8R2235 recone kits, and you can get almost 2235H driver, so some thing like 4333 can be realized.

    regards
    Ivica
