2213H & 123A-3 Mac Kenzie re-cone kits

Yes -a pair of 2213H cones.

The one telling thing, will be the shape of the cone profile.

A true 2213/123A kit will have a bell-shaped cone... flared akin to the end of a trumpet bell. Most of the aftermarket parts I've seen recently, were straight-sided cones... as in the 128H. In fact, most of these have been simply a 128H cone grafted to a fabric surround... which it actually looks like this MacKenzie kit might be.

The cone profile is especially important with 2213H/123A woofers... as they're usually run "wide open" on top, with no low-pass filter. So, the upper frequency behavior is VERY important... the 123A/2213 has MUCH more "benign" breakup modes in its upper range, compared to the sharp peaking (comparatively) of the 128H-type cones. This peaking is not important where the 128H is normally used... the lowpass filter in the crossover "gets it out of there" at low enough of a frequency that the breakup is never "activated" at a significant level...

When you do get these new MacKenzie kits, please do post of a picture of the side of the cone (in profile) compared to the original cone. That will definitely tell a lot...

Regards,
Gordon.

Did you do it?

Anyone tried these yet or know of actual experiance with them?

- My point is that if a recone kit doesn't match the originals' TS parameters / then all claims of it conforming to the original spec. are fraudulent .

ps; Are you going to email McKenzie and ask about their kits' TS parameters ?

And Earl is being ignored, why? Not smart - he's got it.

Lastly, from what I can tell, the 2213H kits are still available; 123A-3's not so much. But I believe you could recone with a 123A-1 kit (available) and invert the signal connections sustaining the OEM negative polarity of the 123A-3. 4313B knows if my hunch is right.

If you want to pay lower prices for non-OEM kits than you're on your own - not recommended here, but good luck if you go that way. If you want JBL spec performance go with JBL kits so long as they remain available. Trusting that you don't abuse your system, this is a one-time expense and therefore more easily justified.

I never did order pair. Sorry about not updating thread.
I still have three pair of 4311's that need 2213H's to be complete.

...the 2213H kits are still available.

That is, if you only need the kits (and not complete drivers).
