Stage X Overview

Martin Logan is an American loudspeaker manufacturer, specialising in the construction of premium electrostatic speakers and subwoofers, including floorstanding, wall mounted and in-wall models. Often regarded as the epitome of electrostatic design, Martin Logan speakers have claimed the hearts of critics and consumers alike thanks to their attention to detail, wide and realistic soundstage and their punchy, immersive portrayal of the sound that they are bringing to life. 

Martin Logan describe the Stage X as being the world's most advanced center channel speaker, utilising Martin Logan renowned and state of the art XStat electrostatic panel technology, as well as a Folded Motion tweeter, twin 6.5-inch aluminium-cone woofers, and topped with highly intelligent Vojtko crossover.

One of the main aspects of the Stage X's superiority is the innovative Folded Motion tweeter, which is located right behind the XStat electrostatic panel within a special housing that offers the aesthetic appearance of a seamless electrostatic panel. This completely irradiated the necessity for a bulky and invasive tweeter-housing, mounted to the front of the ESL panel, the Stage X practically eliminates all high-frequency diffraction.

This specialised mounting method also enhances the mid-range/high-frequency phase coherence and time alignment, while delivering phenomenal dispersion characterises to form a superior sound-stage.

The Folded Motion tweeter technology proves an ideal match for the electrostatic transducers, providing lightning fast transient response combined with a large surface area (8-times that of a typical 1" dome tweeter) to create clear, dynamic and precise sound.
