LINE 400 FS 409

LINE 400 FS 409 is a 3½-way, bass reflex design that offers traditional ELAC performance in a timeless yet contemporary package. The key element to its performance is the Crystal Membrane midrange drive unit of the FS 409. Combined with the JET 5 tweeter, it presents an open sound that incorporates the acoustic characteristics of the surrounding space while maintaining excellent resolution, delivering superior sound with even the most challenging musical material, in every key and in every room.

      • Crystal membrane midrange and bass drivers
        Woofers and midrange drivers in the Line 400 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 used in the FS 409 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 JET tweeter was developed 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. today thanks to additional design changes, 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. 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.
      • Grille magnets
        All Line 400 speakers are equipped with a fabric grille over a wooden frame 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.
      • Bi-wiring
        All Line 400 speakers are equipped with a fabric grille over a wooden frame 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.
      • Speaker feet
        The speaker feet in M8 thread size come with a choice of spike or rubber inserts to provide the required stability, whether on hard flooring or carpet. Both FS 409 and FS 407 floorstanders are offered with a plinth on adjustable ELAC spikes and rubber feet.
      • Down-firing port
        For a more flexible speaker placement and to minimize ventilation noise, the bass reflex port is directed to the floor, exiting the bottom of the speaker cabinet in a down-firing configuration.
      • Aluminum baskets
        To minimize mechanical vibrations and ensure maximum rigidity, the baskets for cone drivers used in the Line 400 speakers are made of cast aluminum instead of pressed or stamped steel.
