Swr/Eden Horn replacement?

Discussion in 'Amps and Cabs [BG]' started by Mad Subwoofer, Sep 25, 2001.

  1. Anybody have any experiance w/ replacing their Fostex horns with something smoother? I think the horn in my Eden D212XLT and 2x10XLT sounds hissy and shrill. i would love to stick some sort of smooth hi-frequency driver in there.....any suggestions?

    A few thoughts come to mind. Have you tried turning down the L-pad on the crossover to attenuate the highs? How about the treble on your amp? Usually the combination of those two will fix it. Another thing is the sound of tweeters changes dramatically if you move off axis. If it's firing right into your ear, it can sound excessive, but everywhere else might be fine. Finally - if all these points don't help, you can try placing some cloth substance in the throat of the horn to absorb some of the highs. It might take a bit of experimentation, but it would be a lot cheaper than finding a different driver.

    It also occurs to me that some bassists plain don't like tweeters at all, so if that's the case, you could unplug it from the crossover and carefully tie back and tape up the open connectors.

    Changing the horn won't affect the level of hiss. The hiss is coming from your bass and amp.

    It MIGHT help with shrillness.

    Claremore OK.
    I hate those things, every one that i have had I either turn it all the way off or unplug it . I like the highs that come out of a speaker alot more they seem to be alot less harsh. MO
  5. Those Fostex tweeters sound very harsh. I already turn the L-pad almost off. Eden says that i will blow it if left like that for too long, and I do pump a whole lot of watts through those cabs. I like the idea of stuffing a cloth in there......
    Some newer cabs use small paper cone drivers instead of horns.

    I love the Fostex/Foster tweeters.
    On the other hand, as far as I know, the Tweeter on Eden Cabs is not a Fostex/Foster.

    I had an Ampeg SVT410HE with a Fostex, and used it at -3 dB for long time without any problems.

    Of course it can sound harsh if pushed to the max, as any other driver.

    I've heard that some horns (piezo, mainly) have self-noise, and that's what I thought he was referring to. Anyone know if the Foster horns are piezo or compression drivers?

    To answer the original question, a P.Audio tweeter would be a likely upgrade candidate - it's the brand Epifani uses and are very smooth. I've heard a few in the Eden cabs and it is a noticeable improvement. You can find the catalogs and retailers online by doing a search for "P.Audio".

  8. excellent! thank you Nightbass...just what I was hoping for. Which does Epifani use do you think? I guess i should go for the 100W model?

    I don't recall which model they use, but anyone with an Epifani could peek inside and tell us. :)

    Yes, using a 80-100 watt compression driver is your best bet, and with the higher wattage you won't need the light-bulb protection device that Eden and SWR uses, and can bypass it so it won't affect the sound (or blow out on a gig). Lightbulbs can have subtle effects on the crossover, to say the least, and guys like Bergantino choose not to use them for that reason.

    The BM Series (www.paudio-europe.com) would be the place to start for an affordable horn. The 80 watt (1" throat) model would be sufficient, or if you want to go all the way, the 100 watt (2" throat) model is available. Don't know what the prices are...
