Technologies :
ELAC has a unique position on the market due to its number of outstanding technological innovations in terms of high end and entry level loudspeakers.

Aluminium-Sandwich Technology :

The woofers of the 200 Series are designed in the ELAC proprietary aluminium sandwich technique. In a special glueing procedure, an aluminium foil of 0.2mm is joint to a pulp fibre cone to form a sandwich membrane. The result: reduced partial oscillations, no distortions and an optimised large signal behaviour Due to the specially wide double asymmetrical ('DAS') rubber surround, ELAC's TT 180 woofer can handle up to ± 15mm long stroke. This provides maximum level supply and mellow low bass. For a driver this size, such a large displacement represent a unique engineering achievement. In combination with the aluminium- coloured tweeters, the aluminium sandwich woofers also make innovative technology a visual experience.

Jet Tweeter Technology :

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 delveloped to perfection on the basis of the famous 'Air Motion Transformer' by loudpseaker 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.

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.

X-Jet Technology :

The best placement for a tweeter in theory is to have the tweeter in the center of the woofer. Some brands have tweeters placed in the center of the woofer. But still have some drawback due to alignment

Fundamentals Of Two Way Speakers :

The new X-JET is a unique combination of a flat aluminium honeycomb midrange ring radiator and a concentrically arranged JET tweeter.

The X-JET driver is the perfect point source in that it is not only coaxial, but importantly also coplanar. It covers 7 Octaves (400 Hz – 50 kHz) and enables excellent off axis imaging thanks to phase coherence on all axis. .

The new X-JET system yields a upper cut-off frequency of 50 kHz. This makes the loudspeaker an ideal component for the reproduction of DVD-A and SACD.

All around perfect sound:

The new 4PI PLUS.2 ribbon super-tweeter is an add-on component that creates a perfect, spacious sound impression when installed on conventional loudspeakers. The combination of direct-radiating loudspeakers, providing precise location and imaging and the omni-directional 4PI PLUS.2 ribbon super-tweeter providing an open and airy sound, results in perfect spaciousness not found with any conventional loudspeaker.
