Kits
The following are just some of the people making enclosures to match our units. Please note that we have not heard the results in all cases, so cannot vouch for them. Contact the manufacturer directly for more information.
Raw Acoustics - Jim Griffin's JX92S mini-monitor designs.
Designs on the Web
The JX92S in particular has been spectacularly successful among the DIY community, generating a number of enclosure designs. We have not heard many of these designs but there have been good reports. Please note that we cannot answer queries about them - the authors will have provided the necessary details and further help is available on the DIY community forums.
We have our own DIY section where we will publish proven designs which have received attention elsewhere. The first to be featured is the MLTL, described below.
JX92S ML-TL - this evolving design has arisen through the Fullrange Driver and DIYaudio forums. Dimensions and plans are given with the designer's approval. There is an attractive implementation of the triangular MLTL here.
J-Low - a no-compromise, back-loaded exponential horn using the JX92S, designed by Nelson Pass.
zHorn - in addition to handmade cabinets based on our VTL, this designer has produced an interesting small rear-loaded horn for the JX92S.
Tuba - a rear-loaded horn for the JX92S, which originally featured in the German hi-fi press.
Peter Millet TQWT - a tapered, quarter wave design from Audio Xpress writer Peter Millet. It uses the JX92S in another MathCad design to produce a loudspeaker capable of taking the JX92S to 35Hz. For further details, visit Peter's website.
Bigger is Better - a six foot tall, half-wavelength, tapered design which has come directly from the DIYaudio community. This website explains the principle and links to the original forum. Click on the Jordan logo for the JX92S design.
Jim Griffin Reflex - winner of the 2001 Atlanta DIY competition, this 7.4 litre JX92S reflex has proved very popular. The designer has supplemented it with a new design incorporating a ribbon tweeter (not a route we necessarily condone but it has been thoughtfully executed and the designer gives his reasons for it). The new design was winner of the 2004 Atlanta DIY competition and a PDF of the design can be downloaded from this link. The enclosure design for both versions are identical.
Robert Cheng, one of the judges for the 2001 competition, was kind enough to send us his impressions of the original JX92S Griffin design:
"The winning design in the open class was a single JX92 in a small vented box, with a shelving filter to help bring up the low end. All judging was done blind with a grille cloth curtain. I was one of the judges and rated this design for best sound quality. I just couldn't believe my eyes when I finally saw what the winner was. Having never heard a 'successfull' full-range driver, I immediately was biased against it when I saw it before judging. However during judging we all found that it had a well controlled low end, though full extension obviously wasn't there, and a very liquid, involving, dynamic character all the way up to the top end. It was missing just a little bit of air, but perhaps that was because of the standard positioning we used for all the entrants, causing the Jordans to be off axis about 10-15 degrees from the judge's sweet-spot chair."
Finally, two forums which often mention our drive units:
Although these drive units are currently unavailable, we are aware that there are still a number of them in use. In response to requests, we have put the original graphs and specifications for the JX125 and JX150 online here. We have included suggested enclosures, including two MLTL cabinets, kindly designed for us by Greg Monfort.
The original JX53 specification page is on site here.
We will update and add to these links as more become available.
