Ushering in a new era for MartinLogan, Renaissance ESL 15A features 15-inch wide Curvilinear Line Source (CLS™) XStat™ vacuumbonded electrostatic transducers, with advanced MicroPerf™ stator technology, and redesigned ultra-rigid AirFrame™ construction; plus, our laser-engineered low-distortion aluminum cone woofers in a compact enclosure, powered by new dual 500-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction) – available in ten beautiful designer finishes.
A Masterpiece in the Making
We consider something a masterpiece when uncommon skill and artistry shapes familiar elements in an unexpected way, revealing an essential truth. For MartinLogan, the essential truth revealed by our skill and artistry is audio realism. Fittingly, their next generation of electrostatic loudspeakers debuts with the new Renaissance ESL 15A. Three decades of audio design and engineering innovation, distilled into a startling fresh loudspeaker ideal.
A Masterpiece of Design & Engineering
The pièce de résistance is the integration of MartinLogan’s award-winning Curvilinear Line Source (CLS) XStat electrostatic (ESL) transducer with its robust woofer section, the revolutionary melding of design and engineering. Now notice some radical refinements: Inspired by our own breakthrough design, MartinLogan has reinvented the Renaissance ESL 15A woofer section. Using two independently enclosed woofers in the compact chamber, exclusive PoweredForce Forward™ bass alignment technology controls the interaction between the rear-firing woofer and the wall behind that woofer. With smart phase-shifting technology, we minimize the effect that wall has on bass information that might bounce back into the listening room. This uniform frequency response results in realistic bass effects you can feel. It’s one more way MartinLogan innovation improves
your listening experience in any room.
Achieving the Laboratory Standard in Your Own Room
For the first time in an electrostatic speaker we are introducing the integration of exclusive Anthem Room Correction (ARC) technology. By engaging ARC, you can experience performance on par with MartinLogan’s audio test lab. ARC measures sound output in your room and compares it to optimal response curves that account for spatial anomalies. The advanced algorithms of ARC then effectively remove the anomalies, leaving only the ideal standard: transparent, natural-sounding performance in the listening space.
Come Closer for More Detail
Clearly, it is this level of ultimate performance that separates the merely excellent from the true masterpiece.
• Two 12-inch Laser-Engineered Low Distortion Aluminum Cone Woofers in a sealed
enclosure – Rigid cast baskets and stiff cones eliminate distortion, while the high
excursion, extended throw drive assemblies produce tremendous amounts of naturallyblended low end in the surprisingly compact, beautifully finished enclosure.
• 15” Wide Curvilinear Line Source (CLS) Electrostatic Panel with gentle horizontal
curvature, enhancing high frequency details produced by the large radiating surface.
• Redesigned Ultra-Rigid AirFrame Technology is precision manufactured from an
aerospace-grade extruded aluminum alloy. The bold, forward-moving styling of this
AirFrame rail system, narrow and strong in front, broad and forceful from the side, is a
modern design statement. It never obstructs playable surface area or interferes with the
panel’s dipole sound radiation pattern. 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 compact
woofer and amplifier section. The breathtaking AirFrame design enhances imaging, lowlevel
sonic detail, accuracy, and speaker efficiency.
• New PoweredForce Forward™ Bass Technology combines two MartinLogan audio
innovations: PoweredForce, which allows small enclosures to accurately produce
massive amounts of bass, and ForceForward, which significantly reduces performancerobbing
front-wall bass reflections. PoweredForce Forward bass technology uses an
advanced crossover topology with phase timed woofers to minimize destructive reflected
energy. By virtually eliminating front-wall bass reflections and working in tandem with the
panel, PoweredForce Foward Bass Technology gives you more placement flexibility,
and enhances the true audio realism of your sound source.
• New Anthem Room Correction (ARC) is an exclusive technology used by
Renaissance ESL 15A to achieve perfect loudspeaker performance in any room. Simply
engage ARC, and the calibrated microphone measures the sound output within your
unique listening space and compares it to optimal response curves. The advanced DSP
algorithms of ARC Technology then instantly adjust your speaker’s output to
accommodate the landscape of your room, virtually eliminating performance-robbing
anomalies such as doors, windows, and other hard surfaces, even furniture.
• New Powerful Dual 500-Watt Class-D Amplification with 24-Bit Vojtko™ Digital
Signal Processing (DSP) Engine produces clean power, in a small space, more
efficiently than ever before. They enable the effortless delivery of exhilarating dynamic
impact, with plenty of overhead. Superior, reliable Class-D technology means there’s
virtually no energy lost between the amplifiers and the woofers.
• Precision-Built Advanced-Topology Vojtko Crossovers are fully 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
driver/ESL integration. This precision-tuned network preserves even the most
microscopic sonic nuances while handling the full dynamics of any source.
• Premium WBT Binding Posts are used to connect your electronics safely and
securely. Their fine silver filigree is highly conductive and free from “eddy current”
effects. These posts are fully insulated for shock protection and topped with an
impressive palladium-plated metal cap, with plenty of room for large-gauge professional
speaker connections.
Renaissance ESL 15A will be available in ten designer finishes, pricing starts at $24,995 per pair (US) and will start shipping in Spring 2016.
