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.
MT 140 AS-XR black anodized diaphragm midrange used in FS 248 BE and FS 249 BE. The midrange driver of the 240 Black Edition Series contains the new "Crystal Membrane" (patent pending) and their design is based on the well-known "Aluminium-Sandwich AS Technology" which avoids noticeable resonances in the diaphragm.The "Full-Roll" fabric surrounding expands the transmission range up to high frequencies to facilitate the crossover to the tweeter. TT 180 AS-XR black anodized diaphragm midbass used in: BS 244 BE and FS 249 BE. The woofers drivers of the 240 BE series contain the new "Crystal Membrane" (patent pending) and their design is based on the well-known "Aluminium-Sandwich AS Technology" which was developed by ELAC a couple of years ago. The crystal-shaped inverse aluminium dome is joined to the paper cone in a special glueing process resulting the desired sandwich construction. The stamping of the aluminium foil looks like the surface of a large crystal, this is where the term "Crystal Membrane" come from. This stamping stiffens the aluminium 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 but also to the bottom of the aluminium dome. 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 ±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 achievemen. |
