The Elkona is just a little too big for a desktop. I think I'll give the new Mark Audio alpair 5.2 driver a shot for my next desktop speaker project, although on paper it doesn't appear to perform as well as the JXR6HD for desktop/near field (especially with a higher Fo).

1st order it would be less than 10 dB down, 2nd order less than 40 dB down

deandob - not to stray OT, for a small desktop system don't overlook the Fostex FF85WK, or the Alpair6P

Hi Deandob - what size enclosures were you thinking of using?

The Eikona will work in small, sealed enclosures - although admittedly not as small as the JXR6HD. A 2.5 litre volume (plus driver - so 2.8L total) would give a Q of about 0.8 and -3dB around 87Hz. Somewhat lower than the JXR6HD.

It is quite a different driver from the JX92 and much closer to the listening experience of the JXR6 at HF.

Colin - can you advise if there are any plans for a new smaller Jordan driver, I guess something that could be considered an update / replacement for the JXR6?

Take a look at the FR88EX if you like the sound of an aluminum cone. This one is very well behaved and has a very flat frequency response. You can even listen to sound clips in Round 5 of the Subjective Blind test threads. Cast alloy frame with neodymium motor.

If it sounds like an aluminium cone, I'd suggest looking for a better sounding driver.

Hi Chris - Ted's always interested in pushing the performance his drive units further and his 50mm format has a long history. If it looks like there's a big enough demand, we might revisit it.

Actually the FR88EX doesn't sound like an aluminum - it just has the ability to hit the solid 20kHz and then some. It does it without huge ringing or breakup.

Yea it does. Not as bad as some and a pretty good driver. Doesn't come with a gasket & the bezel is small enuff that it leaves no room for error (not unsurmountable but a nit). Much better value when they were $30 each (i bought 24 of them)

Not near as good as FF85wk, A6.2m, or A5.2.

Colin, the application is a near field small desktop speaker - basically computer speakers that sit either side of my computer monitor. Current JXR6 speaker is 180mm x 400mm x 150mm (with edges sloped for bsc) and internal volume is 6L. The Elkona I think would look a bit strange in a cabinet of that size due to its diameter.

What about applying the lessons learnt / improvements for the Elkona to make a smaller driver as a replacement for the JXR6? Wasn't there enough demand for the original JXR6 to justify the R&D for a new driver?

Still thinking of trying the new alpair 5.2 as a replacement for the JXR6 but the JXR6 is a great driver & don't want to go backwards for my new project.
