The ELAC JET tweeter is one of the most legendary tweeters in the hi-fi trade and has won international renown with its unusual transparent and effortless sound image.

The JET tweeter was developed to perfection on the basis of the famous 'Air Motion Transformer' by loudspeaker pioneer Dr Oskar Heil. Its principle: a concertinaed foil membrane is driven by a strong magnet system of neodymium rods.

This 'motor' drives the air considerably faster than the conventional pistonic technique. High sensitivity and extraordiary dynamics are the result.

The picture at the left displays the new JET III tweeter with its larger sound orifice. Due to many additional design changes (e.g. new neodymium magnet system) a higher efficiency and a smoother sound pressure level frequency response up to 50 kHz was achieved.

The core of the JET tweeter is the folded foil membrane. With a fold width of only 0.84 mm, a major requirement in the JET production is precision.

Folding under the microscope

To guarantee the repetition accuracy and unchanging quality even with high output, this production step has been automised. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring special dexterity human manual skills are irreplaceable.

Only the glueing and handling are now executed by two SCARA robots.
The absolutely reliable precision of the robot in glueing and handling thus ideally supplements the irreplaceable work by hand.

Due to continuous improvement, the JET III tweeter now creates an effortless and airy resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of DVD-A and SACD.

The wall loudspeakers are provided with a tweeter level adjustment control. The standard position is '0 dB' and it can be used for most applications. If the tweeter output is too strong at the listening position, it can be reduced by 2 dB (position '-2dB').

It can also be increased by 2 dB (position '+2dB'), if more trebles is desired.

The sealed enclosure optimizes the bass response while it minimizes the dust build up internally.

ELAC In-wall loudspeakers are ideal for lightweight walls and ceilings.
