The main part of the frequency spectrum of this model — above 300 Hz — is processed by XStat CLS electrostatic converters with a width of 13 inches (about 325 mm). They implement a number of well-known Martin Logan technologies. The CLS panels (Curvilinear Line Source) used in the Martin Logan Expression SL 13A, as in all MartinLogan electrostatic speakers, optimize the transmission of high-frequency information and stereo panoramas.

    ELAC Vela 2.0 VFS409.2

    The ELAC FS 409.2 floorstanding loudspeaker is equipped with a JET VI ribbon tweeter. The ultralight tape membrane provides an instant response to the received signal, resulting in high sound accuracy. Another advantage of such a Twitter is a very wide frequency range with an upper limit of 50 kHz.

    The rounded corners of the housing not only give the ELAC FS 408.2 an elegant appearance, but also eliminate sound distortion caused by acoustic wave diffraction.

  • Vela 2.0 FS407.2

    The speaker body is tilted back at a slight angle. This ensures the most consistent sound of the drivers and aligns the stereo picture. The geometry of the case in cross-section is close to a trapezoid, the width of the slightly convex front panel exceeds the width of the rear wall. This solution makes it possible to effectively deal with internal resonances.

  • Solano 2.0 FS287.2

    Floorstanding loudspeakers

    ELAC Solano 2.0 FS287.2

    Compact 2.5-way floorstanding speakers. Low-frequency drivers with a diameter of 150 mm with combined AS diffusers mounted on a cast basket. JET 6 branded AMT ribbon tweeter of the new generation. The crossover is made of selected components.

  • Concentro 2.0 M.2

    Floorstanding loudspeakers

    ELAC Concentro 2.0 M.2

    The model is a three-band design in which the main part of the frequency range is reproduced by a coaxial concentric driver consisting of a JET 5 ribbon radiator and a Ring Radiator midrange driver with an aluminum diffuser of a complex Crystal Membrane profile.
