Bi-Wiring
For those interested in the extra detail of treble and bass performance by using separate wires or amplifiers, the ELAC bi-wiring terminal offers
a convenient solution which is easy to access.
High-quality terminals with easily accessible inclined and gilded binding posts are also suitable for larger cable cross sections (16 mm²) as well as for high-quality spade ends (e.g. WBT products).
Crystal
The eye-catching shape of the crystal membrane is far more than just an attractive design: it reinforces the tried-and-proven aluminium sandwich
technique, improving its acoustic behaviour.
All woofers and midrange drivers of this series contain the "Crystal Membrane" (patent pending) and their design is based on the well-known "Aluminum-Sandwich AS Technology" which was developed by ELAC a couple of years ago. The crystal-shaped inverse aluminum dome is joined to the paper cone in a special glueing process resulting the desired sandwich construction.
The stamping of the aluminum foil looks like the surface of a large crystal, this is where the term "Crystal Membrane" come from. This stamping stiffens the aluminum dome considerably which diminishes the membrane-internal resonances resulting in less sound coloration and additionally improves the large signal behaviour noticeably.
The voice coil is not only - like usually - joined to the neck of the paper cone (see position "1" in the picture) but also to the bottom of the aluminum dome (position "2"). This design results in the expansion of the transmission range of the respective woofers or midrange drivers by nearly an octave. Therefore the abbreviation "XR" (eXtended Range) has been introduced.
Due to the specially wide double asymmetrical ('DAS') rubber surround, ELAC's TT 180 woofer can handle up to ±15 mm 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.
Downfiring
For a more flexible speaker placement and to minimize ventilation noise, the bass reflex port is directed to the bottom (downfiring).

Frame w/ Pin
Designed with attention to detail: the cloth frames are mounted with unbreakable metal pins held by rubber grommets in the cabinet – simple and
trouble free.
For perfect grille mounting without any distorting noise at music reproduction, ELAC uses nickel-plated brass pins which smoothly slide into the designated rubber bushings at the loudspeaker cabinet.
JET
High definition audio: ELAC’s JET tweeter fascinates listeners with its dynamic and authentic audio, offering lots of headroom with a distinctly
wider frequency range than conventional dome tweeters.
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.
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. 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.
M8 Speaker Feet
The M8 thread size speaker feet come with a choice of spike or rubber inserts and provide the required stability, whether on parquet flooring or
carpet. Ideal for all speakers with M8 thread inserts.
As a standard, all floorstanders of this series are offered with plinth on adjustable ELAC spikes and rubber feet.
