Giants of sound.
Perhaps the greatest innovation of the Line 500 is the ELAC VX-JET transducer. The acclaimed drive unit, which combines the renowned JET tweeter with a ring-radiator midrange driver in a concentric arrangement, provides the foundation of these speakers’ remarkable sound. What sets it apart is the variable X-JET suspension, hence the designation VX-JET.
The thinking behind this drive unit draws from the fact that every room presents different acoustic characteristics and that the same loudspeaker will produce different results from one room to another. A mechanism on the rear of the loudspeaker allows for stepless adjustment of the entire drive unit by up to 8 mm in front of and behind the front baffle.
By changing the position of the VX-JET, it is possible to fine tune the sound dispersion characteristics in the middle to high-frequency range. This not only alters the tonal balance, but also the relationship between direct and diffuse sound arriving at the listening position. As a result, the VX-JET makes it possible for the first time to create a uniform and precisely etched three-dimensional sound stage in different rooms and at varying listening distances.
Each model in the Line 500 combines the innovative VX-JET with other refinements to make a loudspeaker of true distinction. Critical to the high performance of the Line 500 are Crystal Membrane midrange and bass drivers based on Aluminum-Sandwich technology that deliver maximum stiffness and unrivaled performance within their frequency ranges. Inside are the finest crossover components and outside, beautifully finished cabinets—wherever you look, you’ll discover the ELAC passion for perfect detail.
Crystal membrane midrange and bass drivers
The eye-catching surface of the crystal membrane is more than just an attractive design feature. All woofers and midrange drivers of the Line 500 employ the Crystal Membrane (patent pending) and their design is based on ELAC’s Aluminum-Sandwich AS Technology. The crystal-shaped inverse aluminum dome is joined to the paper cone in a special gluing process to result in the desired sandwich construction. Resembling the surface of a large crystal, the aluminum-foil stamping stiffens the aluminum dome, diminishing resonances and minimizing coloration, while improving power handling and dynamics. The voice coil design of the midrange and bass drivers results in an expanded range of the respective drivers by nearly an octave. The wide, double-asymmetrical rubber surround of ELAC’s TT 180 woofer can handle up to ±15 mm excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.
JET 5 tweeter
Delivering true high-definition sound, ELAC’s JET 5 tweeter enthralls with its lightning-fast response and wide dynamic range, offering minimal distortion, lots of headroom and a distinctly wider frequency range than conventional dome tweeters. The ELAC JET tweeter is one of the most legendary tweeters in the industry and has won international praise with its 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 operating principle is based on a concertinaed-foil membrane, driven by a strong magnet system of neodymium rods. This motor drives the air considerably faster than the pistonic motion of a conventional driver, with gains in higher sensitivity and extraordinary dynamics. Due to many additional design changes, like an improved new neodymium magnet system, even higher efficiency, higher sound pressure levels and 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 repeated accuracy and unchanging quality even with high production capacity, gluing and handling are now executed by two SCARA robots. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring extreme precision, the manual dexterity of skilled technicians is irreplaceable. Due to continuous improvement, the JET 5 tweeter creates an effortless, airy and 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.
All Line 500 speakers are equipped with a metal grille that is attached only through the force of magnets hidden beneath the surface of the cabinet. Listeners who prefer to look at their speakers and listen without a grill will appreciate the clean design and uninterrupted surfaces of the impeccable ELAC cabinetry.
Listeners seeking ultimate treble and bass frequency detail will appreciate two pairs of terminals that offer a convenient solution for bi-wiring or bi-amping the FS 509 VX-JET and FS 507 VX-JET speaker systems. These high-quality, gold-plated terminals offer easy and are suitable for larger cable cross sections s well as for high-quality spade lugs.
The high definition spikes on the bottom of each Line 500 speaker are machined from solid brass with a bright chrome finish. These massive spikes use a M10 thread, and ensure secure positioning and solid, stable footing while providing necessary clearance to the floor.
To minimize mechanical vibrations and ensure maximum rigidity, the baskets for cone drivers used in the Line 500 speakers are made of cast aluminum instead of pressed or stamped steel.
