JORDAN JXR6 HD.

This exciting new driver is the long-awaited successor to the Jordan JX53. It is the world's widest bandwidth 2 inch driver and represents the leading edge of moving cone driver design. It is the culmination of Ted Jordan's 50 years of experience in the field.

The JXR6 HD features the unique Jordan Controflex metal cone in an improved suspension which allows this unit to effortlessly cover the range 100Hz to 30kHz. The resonant frequency of this unit is 80Hz which allows a single unit, in a 1 litre, totally enclosed box, to form the basis for a superb, satellite/sub-bass system. Matched to a suitable powered woofer such as those from MJ Acoustics, a truly discrete, high end, audiophile sound or home cinema system is now possible for the first time.

The JXR6 HD cone sits in a highly advanced chassis. This is constructed of a specialised compound of plastic and polycarbonate, unique to us. It is extremely rigid and resonance-absorbing, making it a very stable, small driver platform. The leadout wires are incorporated into the chassis design, making assembly into cabinets very easy. Manufactured in a specialised facility, the whole unit has a precision camera feel to it.

The JXR6 HD driver may also be used in multiple arrays, facilitated by the rectangular chassis. A Vertical, Linear Array System provides the most dramatic re-creation of live stage realism ever achieved.

Technical note 1

The low frequency response of the JXr-6HD has been extended to a remarkably low limit to enable its in-box performance to be directly matched to appropriate, high quality sub-woofers. To achieve this, the conventional rear suspension has been omitted and the system resonant frequency and 'Q' values are set primarily by the acoustic suspension provided by the volume of air enclosed within a small box. This technique also provides a significant reduction in low frequency distortion.
