Stage™ is a highly evolved expression of the ideas and engineering that spawned the legendary Logos™ and Theater™ center-channel speakers. Incorporating many of our most refined technologies, including a state-of-the-art XStat™ electrostatic panel, twin 6.5-inch aluminum-cone woofers, and highly sophisticated Vojtko™ crossover, Stage sets a new standard for performance in that function. The precision and intelligibility of its center-channel reproduction are unrivaled.

Stage also takes versatility to the next level, working extremely well as a main or surround speaker, mounted on- or off-wall, horizontally or vertically. Only a handful of speakers – our finest floorstanding electrostats – match or outperform it in any of these applications, and none outpace it in all of them. Its sound is always simply glorious.

Stage (Hybrid Dynamic) HD-XStat technology.

HD-XStat™ (Hybrid Dynamic) Technology

What really sets the Stage apart is a high-resolution neodymium soft dome tweeter embedded directly in the electrostatic panel. By eliminating the need for a bulky tweeter-housing mounted in front of the ESL panel (as found on the Cinema and Theater center channels), the Stage all but eliminates high-frequency diffraction. This unique mounting system also increases mid-range/high-frequency phase coherence and time alignment while offering superior dispersion characteristics (compared to previous MartinLogan center channels).

XStat™ Transducer

Advanced MicroPerf stator technology dramatically increases the sound-producing area of MartinLogan's latest-generation CLS™ electrostatic transducer. This increase in effective radiating area translates to higher efficiency and an even more effortless, unlimited dynamic presentation. The XStat pulls no punches!

But there's more to it than just putting more holes in the stators, which must maintain uniform spacing in front of and behind the diaphragm to exacting tolerances. They cannot flex. Stage firmly anchors the transducer's working elements – stators and diaphragm – around their periphery, while ClearSpar™ spacers stiffen the assembly further across its width. ClearSpars enable precise, consistent tensioning of the Vacuum Bonded diaphragm without obstructing the floating, see-through look that is the visual hallmark of MartinLogan electrostats.

In the end, a speaker cannot outperform the signal feeding it. MartinLogan's state-of-the-art toroidal transformer and electrical interface engineering ensure an absolutely transparent link from amplifier to electrostatic panel. The result is sound of unparalleled purity, precision, clarity, and openness – the next best thing to no speaker at all.

Vacuum Bonding

The components of each XStat™ panel – two insulated, high-purity carbon steel stators, plasma-deposited PET diaphragm, and ClearSpar™ spacers – are fused into a cylindrical-section geometry with an aerospace adhesive whose hold strength exceeds that of welding. Our proprietary Vacuum Bonding process ensures uniform diaphragm tensioning and facilitates the extremely tight tolerances necessary for construction of such a precision transducer.

Curvilinear Line Source Electrostatic Panel

One of MartinLogan's original breakthroughs, CLS™ technology has been an essential ingredient of every electrostatic loudspeaker we've produced. Proprietary manufacturing methods enable construction of electrostatic panels as cylindrical sections. Their gentle horizontal curvature solves the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.

MicroPerf Stators

Although stators are the elements of an electrostatic driver that are supposed to stand still, they carry the audio signals that do the work of propelling the diaphragm back and forth to move air and produce sound. Because the stators sandwich the diaphragm between them, they must be perforated to allow sound to pass through. Yet they must also be rigid enough to remain absolutely stationary despite the strong electrostatic forces pushing and pulling at them during operation.

MartinLogan's MicroPerf design optimizes this tradeoff by reducing the size of the individual holes and using many more of them than in a traditional electrostatic panel. MicroPerf almost doubles effective diaphragm radiating area without compromising structural integrity. The resulting increase in output capability and efficiency allows a panel to be made much smaller without sacrificing performance – or to enjoy a substantial leap in bandwidth and dynamics without growing larger.

Low-Distortion Aluminum-Cone Woofers

By eliminating cone flexure, aluminum diaphragms help our advanced-technology woofers achieve the very low distortion necessary for proper blending with MartinLogan electrostatic panels.

Vojtko™ Crossover

Carefully hand-built using only the finest polypropylene capacitors and air-core coils, the crossover employ's MartinLogan's proprietary Vojtko topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

Application Versatility

Stage is suitable for use in any stereo or multi-channel audio system, mounted either on- or off-wall. And it blends well with other MartinLogan speakers in both sound and appearance, which allows mixing and matching to meet specific installation requirements.

Installation Versatility

Each Stage™ LCR speaker includes a single-pivot bracket/stand that enables easy installation on a set-top, shelf, horizontally/vertically mounted to a wall (under or beside a plasma screen, for example), or resting on a floor .

Easy Installation Low-Voltage Power Supply

A low-voltage DC power supply eliminates the need for a traditional, heavy IEC power cord and increases installation flexibility.

Dipole Sound Radiation

Dipole sound radiation.

The sound we hear from a loudspeaker is a combination of direct radiation from it to our ears and reflections off of room surfaces – walls, floor, and ceiling. How our brains integrate all this information is far from simple. Depending on the angle of incidence to the ears and the arrival-time difference between direct and reflected sound, reflections can either blur detail and stereo imaging or enhance the natural impression of depth and openness.

Stage speaker front view.

True dipole speakers, such as electrostatic panels, have long been noted for their near-ideal radiation patterns. They send very little sound to the sides, thereby minimizing side-wall reflections with short arrival times that tend to interfere with perception of the direct sound. Their strong rear radiation, however, produces a generous amount of ambience-enriching later-arriving reflections off the wall behind them.
