Martin Logan : CLX ART
MartinLogan is proud to announce a new edition of the world's finest full-range electrostatic line source loudspeaker. The CLX art incorporates our most popular upgrades including Art Frame styling (with an additional piece of hardwood), stainless steel binding posts, and premium power cords. The standard Linear Frame version of the CLX will remain available through special order. Visit a MartinLogan Reserve Dealer and build yours today. Experience Truth in Sound ReproductionCLX represents the culmination of everything we have learned about electrostatic technology since we brought our first product to market in 1983. Purity of sound permeates your entire room and satisfies even the most critical ear. The industry benchmark for resolving detail, CLX utilizes dual electrostatic transducers to render the most complex musical passages as faithfully as a crystal prism disperses the full color spectrum. This is the limitless spectrum of the CLX - the absolute truth in musical reproduction.57-Inch CLS™ XStat™ Electrostatic TransducerMartinLogan's award winning Curvilinear Line Source (CLS) XStat electrostatic (ESL) technology allows smooth unencumbered dispersion of sound throughout the listening area. The result? Perfectly etched imaging and focus achieved through minimal room interaction; optimum natural reproduction of sound with full level response from ultra-linear transducers; reliable operation in open air; compatibility with all electronics; and seamless dispersion of precise sound throughout your listening environment.
Advanced MicroPerf stator technology gives MartinLogan's latest-generation CLS electrostatic transducer almost twice as much exposed diaphragm surface as a traditional electrostatic panel of the same size. This dramatic 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. 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.
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.57-Inch DualForce™ Double Diaphragm, Triple Stator Low-Frequency Electrostatic Transducer With Dipole Phase StabilizationCLX's unique DualForce double diaphragm, triple stator dipole low-frequency electrostatic transducer delivers deep, dynamic bass with twice as much force as a standard ESL. Additionally, CLX's low-frequency dipole stabilization technology reduces low frequency rear wave cancellation inherent to dipole transducers. This is accomplished by increasing the air path length behind the CLX and delaying the out-of-phase back wave. The resulting decrease in low-frequency front-wave cancellation increases overall output while minimizing total harmonic distortion at low frequencies.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. |
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.
Hand-Rubbed Real-WoodCLX art now comes standard with a gently curved Art Frame and will be available in 4 standard hand-rubbed, real-wood finishes; black ash, dark cherry, natural cherry and maple. Of course, CLX may be customized with any exotic wood finish* you desire, as well as a myriad of analine dye colors, linear frame and premium high-gloss options. * Special order exotic wood finishes take additional time to build and deliver, please talk to your local Reserve Dealer for more information. |
