Martin Logan Theos

Take in on trade. Perfect condition. Works perfectly

MartinLogan is proud to introduce Theos as the most affordable hand-built electrostatic speakers with real wood finishes and custom bi-wire capable binding posts. Descended from MartinLogan's critically acclaimed flagship CLX™ loudspeaker, the Theos features advanced XStat™ electrostatic technology and a proprietary Vojtko™ crossover topology delivering the highest sonic standards of efficiency and precision. A passive 8-inch high excursion woofer and ultra low turbulence down-firing bass port generate unyielding, detailed bass down to 43Hz. Custom coupling spikes and tool-less bi-wire binding posts provide the final touch—providing the ultimate level of flexibility for connection and setup.

XStat™ Transducer
Sharing with its PoweredForce™ counterpart Ethos, a unique XStat™ transducer was developed to exclusively address specific mechanical requirements. Vertically identical in size and dispersion to the flagship Summit™ X, Theos' thinner 9.2-inch (23cm) horizontal panel dimension required a tighter curve to achieve MartinLogan's distinct 30-degree dispersion pattern. To accomplish this MartinLogan engineers reduced the gauge thickness of the steel stators. The reduced gauge does not alter performance characteristics of Theos' electrostatic panel. However, as a natural byproduct of tighter build tolerances, visual transparency of the panel is increased significantly. Theos' new XStat panel is so visually transparent that it nearly vanishes when you're sitting and listening.
