MartinLogan’s newest model features hybrid electrostatic transducers and advanced low-frequency technologies.

Dallas, Texas – CEDIA 2016 – September 15, 2016 – SR-2 – MartinLogan, the world’s leader in electrostatic and Folded Motion® loudspeaker technology, proudly announces a new fully passive floorstanding loudspeaker in its new Masterpiece Series, Classic ESL 9.

Retailing for $6,495/pair (US), the Classic ESL 9 features a Curvilinear Line Source (CLS™) XStat™ vacuum-bonded electrostatic transducer with advanced microperf stator technology, redesigned ultra-rigid AirFrame™ Blade construction, and dual 8-inch low-distortion aluminum cone woofers.

Introducing Classic ESL 9

A New Classic
MartinLogan’s masterwork is our award-winning Curvilinear Line Source (CLS) controlled dispersion XStat electrostatic (ESL) transducer and robust woofer systems—a revolutionary melding of design and engineering.

CLS technology is an essential element of every electrostatic loudspeaker MartinLogan has ever designed. Through our proprietary manufacturing methods, we have built-in the panel’s gentle horizontal curvature. This unique design enhances the high frequency detail and dispersion produced by the large radiating surface, without compromising overall sound quality.

Electrostatic panels, which are true dipole speakers, produce a nearly-ideal controlled dispersion radiation pattern. They send very little sound to the sides, thereby minimizing side-wall reflections, whose short arrival times tend to interfere with the perception of the direct sound. Their strong rear radiation, however, produces a generous amount of natural, ambience-enriching later-arriving sonic information. Classic ESL 9 features a dipolar 9.2×44-inch electrostatic transducer, resulting in a radiating area of 405 square inches per side.

MartinLogan’s new Ultra-Rigid AirFrame™ Blade design enhances imaging, low-level sonic detail, accuracy, and speaker efficiency. It is precision manufactured from an aerospace-grade extruded aluminum alloy. The bold, forward-moving styling of this new rail system, narrow and strong in front, broad and forceful from the side, is a modern design statement. It never obstructs the electrostatic panel’s playable surface area or interferes with the dipole sound radiation. It also provides electrical and acoustical isolation, minimizing intermodulation distortion caused by vibration and resonance. The flowing lines emphasize the groundbreaking integration of the panel itself with the woofer enclosure.

Dual 8-inch low-distortion aluminum cone woofers with rigid cast baskets and stiff cones minimize distortion, while the high excursion, extended throw drive assemblies produce tremendous amounts of low end from a surprisingly compact, beautifully finished enclosure. Classic ESL 9’s low-turbulence ported woofer system extends down to 34Hz.

Classic ESL 9’s precision-built, advanced-topology Vojtko™ crossovers are hand-built using only the finest polypropylene capacitors and air-core coils. The crossover employs MartinLogan’s proprietary Vojtko topology for vanishingly low distortion and seamless woofer and electrostatic panel integration. This precision-tuned network preserves the most microscopic sonic nuances while handling the full dynamics of any source.

Classic ESL 9 will be available in three finishes. Pricing is $6,495 per pair (US retail) and will start shipping in November 2016.
