MartinLogan Renaissance ESL 15A. The Pinnacle of Hybrid Electrostatic Loudspeaker Design
Strikingly iconic and instantly recognizable, the Renaissance ESL 15A stands as the ultimate expression of MartinLogan’s decades-long mastery of electrostatic loudspeaker design. Combining the speed and transparency of a large curvilinear electrostatic panel (CLS) with the power and depth of dual powered woofers, the Renaissance ESL 15A is a bold, elegant presence—visually and sonically.
Hybrid Architecture at Its Finest
At the core of the ESL 15A is a massive 15-inch-wide electrostatic panel, delivering pristine midrange and treble reproduction with signature MartinLogan clarity and coherence. Complementing this are two independently enclosed 12-inch aluminum cone woofers, engineered for deep, tight, and highly articulate bass.
MartinLogan’s proprietary PoweredForce Forward™ Bass technology actively controls rear-wall interactions, ensuring smooth, room-friendly low-frequency performance by minimizing phase cancellations and standing waves.
Room Optimization with Anthem Room Correction
A standout innovation of the Renaissance ESL 15A is its integration with Anthem Room Correction (ARC™)—a sophisticated DSP-based calibration system that precisely tailors the speaker’s low-frequency response to your unique room acoustics, achieving optimal sound in any environment.
Crafted for Acoustic Perfection
The AirFrame™ Blade construction, made from precision-milled aluminum, provides superior rigidity while eliminating enclosure coloration and preserving the electrostatic panel’s open, dipolar radiation pattern. This allows the speaker to reproduce every sonic nuance without compromise.
At the heart of the crossover is MartinLogan’s acclaimed Vojtko topology, hand-built using premium components, and meticulously voiced to ensure flawless integration between the electrostatic panel and the powered bass section—preserving dynamic contrast, harmonic texture, and imaging accuracy.
High-Performance Built-in Amplification
Each bass module is powered by a dedicated 500-watt Class D amplifier, managed by a digital signal processor (DSP) for precision and control. This ensures seamless blending with the electrostatic panel and delivers deep, authoritative bass that’s as fast and transparent as the mids and highs.
