    Do You really think that judging music as music - that is what Mr Shickele is talking about - is the same as judging an audio system for accuracy? Because both should be done by listening?

    What is an "argumentative troll"?

    Thank You.

    OK, what about this system?

    http://www.spectrumaudio.com/2370A.htm


    I have a couple of these horns that I could use with the 2425.

    So the system would be this:

    Low = 2245
    Mid/low = 2206
    High = 2425
    Horn = 2370a

    In this constellation common practice was to use the 2245 as a sub. Using both, the 2245 and the 2206 in parallel at different locations within the room would prevent a bit from room modes etc. To use seperate cabintes would also bettern transportability. A 3-way of this design would be a little bit crude, though.

    Other members have used this model as a starting point:

    http://www.jblproservice.com/pdf/SR-...es/SR4702X.pdf

    That and the 2245's as subs could be interesting.

    Network would need design changes.

    Have fun with it.

    Nicht Schlect

    I actually MADE a set of boxes like this discussion for a small alternative dance club and the requirements were:

    Need it by Saturday ( this was wed afternoon )
    Big and in your face
    Stupid loud
    Poof Proof
    Standard components
    No vocal use ( boom boom hiss hiss )

    So a big pair of cabinets were made with a 2240, 2380 / 2445 in each.

    2360's were not introduced yet or they would of been used.

    Yes they worked, Yes they were loud, Yes the criticallisteningareainthemidrange was crap but who cared.

    In the end everybody ( including my backrent bill ) were satisfied and they were in use for years.

    Moral of the story, none.

    If it works for you, gofer it otherwise woodchuck it

    'sehen sub

    ps - DUDE get a thesaurus

    I do get a kick out of these threads though where someone asks what to do with a bunch of parts laying around.

    Well... sometimes... sometimes they just get irritating.

    hello!

    it would be nice i bet! i love the 2206.
    the subbass is a (imho! imho!) very important part in reproduction, and its to be taken serious, to get it right.
    IF you are open to a little more complicated ways, then make 2way-satellites with the 2206 and the horn, and 2 separate subs (far < 12o Hz), so you can place the subs anywhere in the room where they work best (roommodes, have to find out where they lurk..). important would be to get the delay between the satellites and the subs right, for that you would need something digital (i use a digital active XO) and separate amps.
    --just ideas!

    cheers,
    hope you have fun!!

    Oh YAH!

    Like THAT's a rational comparison of drivers....

    This whole deal is stupid. Are we still trying to squeeze a PE 17.4" wide horn into a 15" wide hole?

    When I get a few spare minutes, I'm gonna retrace this entire scenario; I suspect Romy is not the entire issue here, and perhaps not the primary one, even.

    Now we're gonna use 2370A with HF comp? Not in MY experience and have it sound worth a whit, for sure. I admit not having built up the "improved" filter posted in this forum and actually listened to it, though I herewith threaten to actually do that.

    That's the probem I have with this seemingly endless chain of threads. As others have suggested, at a certain point, the rubber's gotta hit the road; either that or the protagonist does.

    Just friggin' DO it!

    wrong horn?

    My 2370a horns originally came with an SL JBL cabinent with 2225H drivers and the horns were used with the HF compression driver - 2426H. I removed these components, to install them in a furniture grade cabinet and I changed the 2370 factory horns to accomidate the more narrow new cabinet.

    Anyway, is there a reason to not use the 2370 horns with the 2225H drivers, a 2206H mid/low and a 2245h in a single cabinet?

    Well maybe? Have you listened to them?? Some people actually like them and you might be one of them. If you add a compensation cap that brings up the last two octaves and flatten things out.

    Me I am with 4313 as far as using a 2344 or perhaps a 2342 as I think they sound better. If you already have the 2370's try them out first. It's not like you can't change the horn down the road but you would also have to change the crossover as well though so keep that in mind.

    Rob

    When I was going to use the 2370/2425s in my four surround speakers, I developed these through many hours of trial and error and listening and Behringering. You would want to adjust the Zobal network to the woofer you intend to use.

    The shown compensation actually worked better for the 2370 than the P-audio horn. Ultimately, Linda preferred the aesthetics of the P-audio horns mounted within the cabinets, rather than the 2370s hanging under the cabinets even though this reduced the cabinet volume hurt the bass response.

    SR horn test

    Yeh, I listened to the JBL 2370 horn for a few months in my basement when it was in factory trim in front of a 2426 compression driver with a 2226 woofer in carpet covered factory trap cabs.

    The HF response was a tad bright at the high end, so when I installed the components in the furniture cabs, I added a 2405 slot crossed at 7K and I used a different deeper but more heavy narrow aftermarket plastic horn. This configuartion completely changed the system performance.

    Anyway, if I go with a 2245, 2206, 2425 and the 2370 horn, I suppose I could add a tweeter later...
