Hi
I found a picture of the modified jx92s.Hope it hasn't appeared before on this forum.Did the search and only found some members requesting the possible mods to this fine driver.
Has anyone done this mod? It looks but ugly,then again maybe with the same colour wood as the enclosures.....
Didn't the jx92s have a sort of "axle" inside it,which moves with the cone?

Though it is still WAY expensive...that price includes an enclosure. Currently Carolina audio charges 2500 for the speaker.

The old Jordan-Watts module did not have rods, but a rather unconventional spider.
This consisted of three long very springy berylium wires fastened tangentally to the top of the voice coil/cone junction at one end, and to three solder tags at the junction of the magnet/ main housing. They were spaced equidistant from each other.
The length of these and the tangental fastening allowed them to flex, but did cause the cone to have a small rotating motion.
This worked very well, but the solder tags are fastened to the frame by small screws which are not strong enough to stop the wires moving under shock loading of the (relatively) heavy cone when the unit is moved. This allows the cone to go out of centre and the voice coil rub. However recentering can be carried out with a bit of care.
The front cone surround was conventional foam, but square rather than round in shape.

Late reply,but funny to see that "6moons" was also mislead about the jx-92s.
Konus Essence review:
"With its aluminum die-cast chassis, "Controflex" metal foil diaphragm and unique spider that attaches to the cone's center via a light metal tube passing axially through the magnet, the JX92s is very special."

Seems this thread is a classic case of a problem with this forum. Too many wanting to be the expert on any or all given areas.
Let us assume that in the Jordan Watt era that production changes were made just like production changes are being made in current jr6x series.
Thus, just because the information any given self appointed expert may have is different, doesn' t mean that every other possibility is wrong.
Indeed, there was a production series of Jordan Watt modules that used a rod connecting the center of the metal cone through the vented pole piece to a suspension element located behind the magnet assembly. Voice coil leads were also wrapped around this rod and were connected to multi-strand wires also mounted on the back of the magnet assembly.
I have a sample of this version of the Jordan Watt module. Just because I have this sample does not mean that there were not versions using wires for the rear suspension and so on.
Think more and post less,
Mark

Hi Mark,
"Seems this thread is a classic case of a problem with this forum. Too many wanting to be the expert on any or all given areas."
This is what happen with any forum, not necessarily a "problem", without members contribution we won't have a good forum, sometimes we can cross check information this way, and get more information from others contribution, I wouldn't put people opinion as "wanting to be the expert" though, most of the people who ask question would be happy if there's any information.

This is a very good information, thanks, keep posting !
cheers,

Can you post a picture of this Jordan Watts module you are talking about? My Jordan Watts modules don't seems to have anything from the center of the cone through the pole piece.
I would like to obtain a pair of these you talk about if they are available.The only models I know of with rods going through the pole piece are the JX125 and JX150.
