FS 248 Black Edition: Ein Lautsprecher wie aus der nächtlichen Silhouette New Yorks entnommen

Ein Lautsprecher wie aus der nächtlichen Silhouette New Yorks entnommen: Schwarz, hoch und extrem schlank. Sie ist der Skyscraper von ELAC. Optisch wie akustisch. Transparent im Sound besitzt die FS 248 Black Edition präsentere Höhen als jeder andere Lautsprecher dieser Linie. Die perfekte Percussion-Performerin.

Treble Unit

JET III used in all 240 Series range.

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. 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.

Midrange Unit

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.

Midbass Unit

TT 150 AS-XR black anodized diaphragm midbass used in: BS 243 BE, FS 247 BE and FS 248 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.
