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 CONCENTRO M 807

    The Concentra M 807 is a masterpiece in form and function. The sculptural case, developed in collaboration with a renowned Hamburg design studio, shows elegant contours, refined surface finishes and a seamless mixture of high-gloss lacquer (black or white) with aluminum accents. The flowing curves and sloping surfaces are not only visually striking — they also serve acoustically and optimize the sound dissipation.

    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.

    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.
