Theos Overview

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.

Advanced Vojtko Filtering

Proprietary Vojtko filtering technology is utilized for Theos’ electrostatic transducer. This audiophile quality network, derived from the CLX, is carefully hand-built using precision point-to-point wiring, polypropylene capacitors, massive air-core coils, and a custom wound E-I core transformer—flawlessly preserving micro-acoustic subtleties while effortlessly handling the broadest range of dynamics contained within even the most demanding sonic source.

Bi-wirable Tool-less Binding Posts and Low-Voltage Power Supply

MartinLogan’s proprietary tool-less binding posts simplify cable connection and management. Two sets are supplied—one connected to the electrostatic panel and the other feeding the woofer. Listeners can choose to vertically/horizontally bi-amp the Theos, or use jumper clips between the binding post sets for a single wire-connection. Theos features bi-wirable binding posts and provide the ultimate level of flexibility for connection and setup. To further simplify setup and cable management, the Theos features a low-voltage DC power supply eliminates the need for a traditional, heavy IEC power cord.
