Stage X

Ultimate-Performance Electrostatic Center Speaker

The world's most advanced center-channel speaker, Stage™ X is an ideal home theater companion to our other XStat™-based loudspeakers.

Designed primarily to serve as the center in a home theater incorporating other XStat™-based MartinLogan electrostatic speakers, Stage™ X is versatile enough to handle left-, right-, and surround-channel duties as well. Its dual 6.5-inch aluminum-cone woofers, Folded Motion tweeter, and advanced Vojtko™ crossover seamlessly integrate a solid bass foundation with the astonishingly transparent, detailed midrange and treble produced by its XStat panel. A single-pivot bracket/stand facilitates set-top, shelf, on-wall, or on-floor placement.

MartinLogan Montis and StageX Speaker Review

"The MartinLogan Montis Hybrid Electrostatic Loudspeakers can rightfully be expected to perform exceptionally as stereo music listening speakers, and they do. Mated with the StageX center channel speaker, they can form the heart of a smashing fine home theater system. I can report without reservation that these speakers are excellent choices for either type of duty… The user who wishes for a quick setup will get very good results. And the user seeking audio perfection will find few loudspeaker “tools” to work with like the Montis at anywhere near the price range that are more likely to please."

MartinLogan Stage X Electrostatic Hybrid Center Channel Speaker

"Being a huge fan of electrostatic speakers, I have always been worried about dealing with the center channel, because there weren't any electrostatic center channel speakers available that covered the high frequencies as well as the midrange. I didn't have the opportunity to test the original Stage version of this speaker, but I can say that the Stage X is one superb-sounding center channel, with everything above 450 Hz being covered by flat panel speaker technology. Having the ESL portion in the midrange is a definite plus, as this is the most important region of the audible spectrum"
