Martin Logan Renaissance ESL 15A

Martin Logan Renaissance ESL 15A — Befitting a loudspeaker of this name, MartinLogan has combined decades of innovations, and more, to reinterpret the uniquely detailed electrostatic loudspeaker. This is a flagship audio achievement for the 21st Century.

 

The pièce de résistance is the integration of MartinLogan’s award-winning 15-inch wide Curvilinear Line Source (CLS™) XStat™ electrostatic (ESL) transducer with its robust woofer section, the revolutionary melding of design and engineering.

 

Look at the familiar elements of the classic MartinLogan electrostatic loudspeaker: Advanced MicroPerf stator technology, which allows for almost twice the exposed electrostatic diaphragm surface as a traditional electrostatic panel of the same size. The panel is reinforced with rigid ClearSpar™ spacers, keeping an exact level of tension on the vacuum-bonded diaphragm without obscuring the beautiful see-through design. Add the slender, pointed-arrow design of the new AirFrame™ Blade construction; a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet.

 

Now notice some radical refinements: Inspired by our own breakthrough design, we have reinvented the Renaissance ESL 15A woofer section, powered by new dual 500-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).

 

Using two 12-inch laser-engineered low-distortion aluminum cone woofers in independently enclosed compact chambers, exclusive PoweredForce Forward™ bass alignment technology controls the interaction between the rear-firing woofer and the wall behind that woofer. With smart phase-shifting logic, 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.

 

Renaissance ESL 15A XStat panels are joined to their speaker cabinets using MartinLogan’s redesigned AirFrame Blade construction, precision manufactured from an aerospace-grade extruded aluminum alloy. This material, and this exclusive manufacturing process, makes the panels extremely rigid.

 

The bold, forward-moving styling of this AirFrame Blade 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 Blade design enhances imaging, low-level sonic detail, accuracy, and speaker efficiency.

 

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 performance-robbing 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 Forward Bass Technology gives you more placement flexibility, and enhances the true audio realism of your sound source.

 

Connect your electronics safely and securely using 5-Way audiophile WBT Binding Posts. Their pure copper connection plate is highly conductive and free from “eddy current” effects. These posts are insulated for shock protection, and fully damped against vibrations. They give you plenty of room for large-gauge professional speaker connections.

 

The performance of Renaissance ESL 15A has been reconsidered from the ground up. Taking full advantage of innovations like PoweredForce Forward and ARC Technology, and the integration of the electrostatic panel with the woofer array, required daring thinking about power and efficiency. Our new dual 500-watt amplifiers produce 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.
