    Yes, If I'm going to do this, I want to do it right. This will be a long term keeper & this way I know that everything is correct.
    Have ordered the recone kits & have a contact of Brisbane Sound to do the reconing. Will keep all up to date on progress.

    Hello Sootche
    I'm planing to buy a recone kit for 2235 .Where do you intend to buy a good recone kit close to the original C8R 2235 .There 's a lot of shop in Usa and I don't know where to order .
    Best regards
    Alain

    2241H!

    More volume, better articulation and detail than a 2235/2245, and can take what you throw at it.

    Doesn't require a huge cabinet like a 2245.

    Doesn't go as low as a "foam job," but a bit of eq can take care of that. Depending on the cabinet tuning, does have a very nice "bass bump."

    Not highly sought after and can be had very reasonably (=<$$$). And, never needs a refoam!

    Run WinISD and compare this to all other JBL woofers and you will be suprised of its capabilities. Blows away everything else, except the foam jobs, for deep bass.

    For clarity the 2234 was used in pairs per the 4435 with box frequency of 26 hertz

    http://www.jblpro.com/pub/obsolete/443035.pdf

    The sensitivity of a single woofer is 96 db

    The second woofer has a low pass filter above 100-150 hertz at 6 dB per octave

    The tuning in the 4435 is an over damped alignment where both drivers “add”and level the response to 30 hertz

    Thanks for the tip, but I don't want to go 18" for the bottom end - need to get all the way up to 500Hz for the first crossover point.

    I'm located in Australia, so can't really help you with kits from USA. Take Dr db's advice re German distributor.

    Thanks Ian,
    So just a simple low pass filter on one of the woofers.....sounds good. Now you've piqued my interest in the 2 woofer set up, although the cost will hold me back just at the moment. It's costing a small fortune to get the drivers, plus then the recone kits & then have someone recone them.......let's see how I like the sound of the single woofer set up.

    2241H goes higher than a 2235H and easily gets to 500 Hz. (Actually rated from 30-3kHz whereas 2235 is rated to 20-2kHz.) Vocals are more intelligible and articulated than a 2235. Also reverb and decay are improved as is the stereo image. I don't know how much dispersion (if any) you would loose over a 2235 crossed over at 500 Hz though, if that is an issue. I always sit in the sweet spot.

    Good to know, thanks.
