Ultimate JX92s suggestions

britbug · 18th March 2008, 08:35 PM

Hi all.
I had installed my JX92s in an old bass reflex set of speakers (Gale 4, blast from the past indeed!) and they were so good I haven't gotten round to doing anything else. The lowther's have it on very good recordings, but the Jordans make almost anything bearable (unlike the lowthers).
Still, I would like to build a custom enclosure for these babies, and would like suggestions. At the moment, the toss up is between the Jordan VTL & the BIB, to be used full range as-is.
Thanks all
Graham

You should definitely have a serious look at GMs MLTL enclosures:

Theres plenty of info about them on these forums and they are considered an excellent application of the JX92s

Graham,

I use the GM MLTL as the base enclosure for my 'Jordan with a Ribbon MLTL' design as in the thread:

Jordan with a Ribbon MLTL

If you start with the MLTL enclosure that I suggest, the Jordan JX 92S driver can be used alone--full range with a little baffle step compensation. The baffle step comp circuit is typically a 1.5 mH inductor and parallel with a 4 ohms resistor. That circuit is then placed in series with each JX92S.

The MLTL enclosure is simple to build and makes for a petite floor stander which has much appeal if SAF is a consideration. If later you wish to add the Aurum Cantus G2si ribbons and crossover, you can do so with only a simple tweeter cutout mod to the enclosure.

Go for the BIB! The comparisons I've read (and the single one I've done) put the MLTLs above the VTL, but no one has yet reported on the BIB design. Be a pioneer ...

BTW, nice comment on Lowther vs Jordans; I've often wondered how they would compare.

Hello,

the TUBA would be a solution.

Hi Graham,

I prefer the MLTL over the VTL, I built both. The additional ribbon tweeter as proposed by Jim Griffin gives also cleaner response.

But have in mind, they won't do really deep bass. Therefore I built a sub-woofer for my sister recently.

Regards
Stephan

Hi Stephan - Which MLTL did you build? I found my compact sub didn't really add anything to the 48 MLTL at 30Hz, but I imagine one would go well with the 31.
