    Anything bad to say against Mackenzie recone kits?

    Except, of course, that they are not original JBL.

    Considering that 2240 baskets can be had for under $50 and that a pre-assembled 2245h recone kit is $80.00, I think it becomes a no brainer for bass heads.

    Making a part properly is not more difficult than making it wrong. It only has to do with starting on the right foot and setting up the job properly.

    if I were a JBL collector, I'd maybe spend extra for the original part just to show my friends the white greasy pen in the back of the cone. But as a user who might blow a few cones in the driver's lifetime, paying $80 instread of $240 makes a difference, especially if the sound was to be identical.

    Some of you guys make this sound as if it's so easy to knock-off JBL moving assemblies with precision. Especially these people that can't get factory parts. Proof is in the pictures.

    It doesn't take many $80 blown-up recones to amount to buying the right stuff that will give the expected performance for years to come...even decades to come.

    I had a regular customer recently bring in 2 fried 2241G that were reconed by the regional aftermarket hack that claims he uses the "same parts that JBL uses". Not true in the least.

    Moral of the story...customer wasted nearly twice as much money by trying to save money. I showed him the differences between the parts. He was not amused at his folly.

    I don't either, but here is couple of things you should check:
    the voice coil must be 24mm long (vs 19mm for the 2240), edgewound copper ribbon, and the cone must have aquaplass on its back (mms 185g vs 164g for the 2240).

    The fact that their 2245 kit is more expensive than their 2240 one is encouraging!

    Interestingly, I don't think that all JBL-sourced 2245 kits even had the white aquaplas on the back. I have noticed some discripencies on many pictures. But I might be wrong.

    aquaplas can be either white or black (eg 128H vs 128H-1), but is present on the back of all proper 2245s

    When a supplier such as JBL doesn't sell components for a while, and sells replacement parts at highway robbery price, I think the message is clear: bring your business elsewhere. Therefore, as Eaulive mentionned, I think it is the enthusiasts' best interest to support local aftermarket suppliers into improving their product. "Supporting" could include working with them into making better recone kits. If it allows a couple American workers to get a job, I am all for it...

    Perhaps I can even invite the dudes from Mackenzie to this discussion. Afterall, aftermarket suppliers are not neccessarely the ennemy.

    The JBL OEM 2240 recone kit has aquaplas on about 1/3 of the rear of the cone up from the voice coil apex. 2245 has black aquaplas on the entire rear for the cone. Older 2245s had white aquaplas.

    The problem with aftermarket cone suppliers is honesty. You will not get JBL performance from aftermarket kits. If you're willing to understand and accept that the aftermarket kits are considerably inferior, that's your choice. Most JBL fans want JBL performance and longevity.

    VGC aftermarket kits are not worth the money. The voice coils are completely wrong and will burn up.

    Caveat Emptor in the aftermarket. I've seen too many lies on incorrect repairs. If they're honest, no problem...you been disclosed.

    Notice any obvious differences from the aftermarket pictured a few posts up? Aquaplas? Voice coil?

    Obviously, voice coil length and lack of aquaplas, there maybe more.

    This is exacty what I'm referring to. If JBL specs could be available or properly measured so that the third parties could accurately reproduce them, I think it would be a bonus for everybody.

    Maybe not for you however, since your business is professional reconing.

    Just for fun, could you provide the VC length for 2225 and E140? Do you know about offsets and the details involved in making a cone/VC/spider assembly a genuine JBL cone?

    At the base it's only paper, copper and glue.

    JBL needs not to publish specs. Any manufacturer could reproduce an exact copy by simply spending $240 on an original recone kit, and spend some time measuring it and trying to reproduce the exact same specs. Spider and suspension flex, cone rigidity and weight, voice-coil, etc. Make a first copy. Test T/S. Modify if necessary. Damn, if humanity can send men on the moon and make zoophilic porn available to every single house in the world, how come copying such a simple part is so difficult?

    JBL drivers are not rocket science. They are industrialized mass-produced parts.

    JBL 2225H

    Total weight of assembled cone. 86g.
    Add 2g. for dust cap. Glue weight for dust cap dependent on artist!
    Coil former height. 1.125"
    Coil winding height .680"
