ELAC FS507 VX-JET

The FS 507 VX-JET combines the innovation and elegance of the larger FS 509 VX-JET in a more compact, 3½-way, bass-reflex design. It makes music come alive like almost no other loudspeaker, and no matter where you position the FS 507 VX-JET, it performs at its best thanks to the VX-JET driver. From the deepest lows to the airiest highs, it creates a breathtaking listening experience.

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 step-less 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 Aluminium-Sandwich technology that deliver maximum stiffness and unrivalled 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.

Delivering true high-definition sound, ELAC’s JET 5 tweeter enthrals 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.
