    More 2440 help

    all so I'm going to be running my 2440's around 6 or 700hz to around 8khz or so. Any advise on a good horn to use for a home system? I was looking at a 2380.thanks,Nick

    The Bi-radial 2380 and all other modern JBL horns need equalization to achieve some semblance of a flat frequency response... this is by design so that the JBLs can offer very controlled directivity with similar on and off axis response. The older style exponential, radial, and hyperbolic horns do not preform this way... what I am getting at is that you can't just swap one for the other if you are after a high performance system.

    For home duty, perhaps you could find some Emilar 500. They usually go for well under $100 a pair, except on eBay where they have that special version made from a special casting with a very high content of specially formulated greed that is worth $800.00

    You could aslo get some JBL 2397. I was about to suggest some 2350, but those are long throw.

    Eh-500

    I paid $100 ea for mine a couple of years ago and haven't seen a pair cheaper since. I don't know of anybody using them, but if I could usually find them for well under $100 a pair, I'd be listing them like mad on eBay.

    That guy had two sets for $60 per set. I was too lazy to buy them.

    I have seen many sets for under $100.00

    Yeah, I do remember seeing those come to think of it, but I've never used CAM.

    Have you ever used a pair?

    Not yet. Still looking for at "regular" price. I do already have some 2350, 2395 and 2397 clones. I'd be interested in testing some Emilar 500 or Iwata 300.

    It seems these Polish horns have had good reviews. A member here and others on AVS forum ordered them. There's a review of the Iwata 300 on the forum.

    I'm going to buy some horns from them. Probably got to buy some pa horns to start with. Maybe the emilar or a gauss 4140.

    Still would like to build my own wood ones some day.

    All horns don't have the same specificities, therefore it's fine to have several models

    Hi Widget,

    About the 2380, I looked at the datasheet and the frequency response doesn't look too bad. I would be cutting it off at 8k. It seems to me that the issues happens around 9k.

    Am I correct or not?


    Thanks,
    Nick
