2-way TL designs using Jordan JX150

[Al Garay]

Hi,

Are there transmission line designs using the Jordan JX150 or JX125?

Are any of these suitable tweeter options:
* Hiquphon OW1F (87db, $US90)
* Seas T25CF002 Millenium (88db, $US155)
* Northcreek D28-06S (new, 92db, $US78)
* Fountek JP2 ribbon (98db, $US118)

Basically, I'm considering a TL similar to rljones' Jordan 92S TL + ESg2 ribbon except using the JX125 or JX150.

Thanks for the advice,

Al

Ribbons probably a better match for the JX150. Best of all is the JX53, which the 150 is designed to match.

Thanks for the feedback.

www.salkaudio.com has a Veracity HT-1 with a better combination of a ribbon and woofer than the Jordan. For less moolah, there is a good OW1, woofer combo already built(heresy!).
Our own RAW has a ribbon/Jordan combo built for Jim Griffin, PhD that is probably a mind blower.

If you want a wider bandwidth system, particularly into the bass, the JX53/JX125 or JX150 combo is probably still the one to go for. I was advised by Ted that the JX125 is a better bass driver than the JX92 (since that was, after all, what it was designed for).

The overlap at crossover between the two Jordan units is quite large and the fact that they are similar designs of cones, materials, horizontal dispersion, etc makes for a very seamless transition. IMHO, probably about the closest to a single driver in two units.

The Jordan DX55 is pretty flat out to 20K. You might find it
workable without a tweeter. I did.

i did a TL design for the JX125 (for someone else never built it).

A friend had JX150 and until he managed to get JX53 he found a fostex ribbon to be the best match... then he used the jx53 with a series XO about 3.5k... now he just runs the JX150 full range. Mine are still in their boxes, but i'll get them into something someday.

Hi David,

Did I understand correctly:

Your friend prefered running the JX150 full range more so than the JX150 with the JX53? What provides coverage above 5kHz?

Thanks for sharing your design.

Yes... a stock JX150 actually goes right up -- at least by the spec it goes up to at least 10k



And who knows what the C37 on it actually do... both him (& 7th Viel Steve -- different "Jordan" driver) say it is a positive improvement.
