New Jordan driver - preliminary details
 
Preliminary tech specs for the new Jordan JX92S replacement have gone up on the Jordan website

Jordan loudspeaker drive units


The measurements are for prototypes. There is also a photo of the new driver.

Looks really good both from a performance point of view and cosmetic. Good to see they are now UK made too. Look forward to getting hold of a pair.

Looks interesting. Unusually low mechanical damping. Be nice to see a more detailed waterfall plot.

looks interesting. Is this a "heat pipe" kind of thing?
I think dampening of the surround is pretty high. Cone resonance is around 9k and it's not more then 5db without THD going through the roof. But I'd wait for more measurements to come out before making any sort of assumption.

Looks like a phase plug ??

The centre plug is a phase plug. The entire driver is a little more compact - the chassis is different and there is no cancelling magnet on the back.

Re the waterfall - I presume it's not worth doing a more elaborate plot until the production model is available.

You mean a low Qms, high mechanical damping... with numbers like that we have a candidate for current drive :)

Major technical parameters are close to the original JX92S,enabling them to be used with the same or very similar cabinet alignments.
The parameters are close to the old JX92, not the EAD JX92

Hmmm....

Nothing to get excited about so far compared to the 2008 version tested by Zaph.

Very low Qms is usually the remit of very budget (AV) drivers, I can see what P10's
comment is about regarding the low Qms, but most are very suspicious of very high
mechanical damping due to possible / probable hysteresis effects.

I don't know the politics, but I'm expecting it to be a very expensive driver for what is.

rgds, sreten.

Hi,

I see in the picture that the external shape is no more circular. Does it mean they can not replace old JX92 drivers in old cabinets?

It would be really a pity
