The Focus ESL C18 is a very stylized - only 234 mm deep - acoustic screen specifically designed to reproduce the critical central channel of very high performance Home Theater systems in order to guarantee a reproduction of voices and effects of pleasing realism environment . It incorporates an electrostatic panel of 457 mm of width by 191 mm of exclusive height of MartinLogan, one of the innovative speakers of acute with folded diaphragm "Folded Motion" of the same brand and two ultra-compact electrodámicos woofers with cone of aluminum. In the case of the electrostatic panel, this is the most advanced version of the legendary MartinLogan CLS curvature sound source transducer, the CLS XStat, which thanks to a unique configuration as regards both the mobile element - the diaphragm itself - and To the excitation system allows to reproduce the frequencies between 470 and 3000 Hz with an exceptional precision, while the particular profile used guarantees an unprecedented spatial presentation thanks to a unique dispersion pattern. With regard to the "Folded Motion" tweeter, the fundamental element to note is that the "folded" character of its diaphragm allows a substantially larger emission area than a conventional tweeter dome, Speed ​​of response and a higher definition as a consequence of the extremely low mass of said element and the control exerted on it by the powerful magnetic motor that accompanies it. The Focus ESL C18 is supplemented by two 165 mm diameter aluminum cone bass speakers designed for large displacements that, mounted on a non-resonant camera, guarantee perfect reproduction of frequencies up to 50 Hz.
