Jordan JX92S build - Anyone tried this design?

[hifimaker]

I'm thinking about building a pair of full range Jordan JX92S's. I'm wondering if anyone has experience with this particular build?

Seems like this cabinet produces great full range response. Certainly 35hz is pretty low for a FR driver set-up.

Thank you for your comments.

Well yes, I have experience with these as I built them.

They have been a real show stopper for me since completion. I have not had the urge to build anything else since finishing these. That says something to me. I doubt they go that low to be honest, but in my small (9' x 12') room the bass has a real snap and thump to it. Highs are nice and rounded to my ears. They were a crowd favorite at a local audio get together this summer as well.

I'm not good with reviews and words, but feel free to ask anything you may have questions on.

Those are tall enuff that they would be ML-TLs, WinISD isn't going to be able to accurately model them. Those same cosmetics could eaasily be used on a GM 31" ML-TL.

Thanks guys for the help.

Gary, have you combined these speakers with a sub? My room is 12'x17' in size, so pretty similar.

Where are you located in MN? I'm originally from Duluth.

I'm in St Paul.

I have not used a sub yet. I picked up an old M&K sealed sub, but the driver needs some work. As a good friend said to me the last time he listened, "a sub will be an experiment in this room." They really do bass well, the best I've heard from a fullranger.

The drivers in them now have the EnABL treatment. Not a big difference in sound from the stock drivers, but a tad different sound.

Gary, How did you arrive at the cabinet dimensions? Did you experiment with different size boxes, sim, or listen to other designs? Your wood work is impressive - very attractive choices on veneer and finish.

Dave, From your experience (which is considerable) is this a good cabinet dimension? Are there other sizes to consider?

Thank you!

Hi David


I built something very similar to these:

I used a bottom firing port, and a slightly smaller cross section. I have been listening to them for about 6 months and I am very pleased. I am waiting for Dave to draw up plans for the half-jimi chang. Scott has designed the half-jimi, and Dave is going to draw the plans for me. I will email him today to see if he has had time.

Hey Jim.

I'll be watching for you're thoughts on the half-jimi as I have a pair of Jordans looking for a cabinet design.

That is a nice looking bass reflex implementation with the JX92S. Over the years I enjoyed all of my Jordan designs (mini-monitor and MLTL variants).

The looks of the bass reflex is akin to both of Greg Monfort's (GM) 48 and 31 inch MLTL designs. These designs are mentioned on the Jordan website and have been discussed here on the DIYAudio.com site. Several people have successfully built this design and have reported excellent results. These MLTL versions are straight transmission lines so implementation is similar to the bass reflex version except stuffing is used around the driver.

Furthermore, the MLTL design accounts for the distance between the driver and port inherent within the tower. Most bass reflex box design software programs do not account for the height of the tower. You'll need baffle step comp with the MLTK implementation unless you use the speaker against the wall.

I have a Jordan JX92S with a ribbon design that uses Greg's basic 48" MLTL but adds an Aurum Cantus G2si ribbon tweeter to take the design to a new level. With the 48 inches MLTL you can achieve low end F3 performance in the mid 30 Hzs area. Again you can search for the DIYAudio.com threads that cover details about this with ribbon design.

Jim, Thank you. This was incredibly helpful and informative. Thank you also for the research pointers and sharing your experiences - really appreciated.
