JORDAN BASS DRIVERS.

The JX125 and JX150 are enhanced technology, high performance bass drive units, designed to complement the JORDAN JX53. Used in conjunction with a first order crossover, they provide a seamless, step free sound quality throughout the audio spectrum. The unique JORDAN Axiline suspension system keeps parameter values constant at all power levels, facilitating accurate enclosure design.

Although the units are no longer available, the basic specifications are given below for those who still have these units. Greg Monfort, the designer of the MLTL enclosure for the JX92S has also supplied MLTL designs for these drivers.

ENCLOSURES

The JX125 and JX150 will work with either closed or vented enclosures. Recommended volumes are:

MLTL ENCLOSURES

Using Martin King's MathCad program, Greg Monfort has kindly provided the following designs for the JX125 and JX150. (Please note that we are unable to enter into correspondence regarding this design.)

MLTL-JX125 Height - 57.28" Width - 8.3" Depth - 10" Driver centred 20" from top Port - 1.5" diameter x 4.75" or 6" long (experiment with port length to give the desired in-room roll-off) Stuffing - 0.2lbs per cubic foot Polyfil   MLTL-JX150 Height - 59.1" Width - 10" Depth - 11.37" Driver centred 21.33" from top Port - 1.5" diameter x 4.5" long Stuffing - 0.2lbs per cubic foot Polyfil   GENERAL NOTES All dimensions are INTERNAL. The stuffing (shown in grey on the drawing) is based on computer simulations - as always adjust to suit. Recommended material is 18-25mm birch ply. The backside of the driver cutout should be bevelled at 45 degrees to reduce reflections. The internal depth, width and shape can be adjusted as long as the overall cross-sectional area remains the same. The port exits through the front panel and should be placed as close to the bottom of the enclosure as practical.
