MartinLogan Classic ESL 9 Speaker

The 9.2-inch XStat electrostatic transducer uses a thin, lightweight diaphragm that moves with extreme speed and precision. This design minimizes distortion and provides a level of clarity and transparency that traditional cone drivers often struggle to match.

The dual aluminum cone woofers are arranged in an opposing array to cancel out cabinet vibrations. This configuration allows the speaker to produce deep, punchy bass while keeping the sound clean and free from unwanted resonance.

While these speakers are engineered for transparency and work well with a wide range of electronics, they perform best with high-quality amplifiers that can handle their impedance characteristics. Ensure your amplifier is stable into 4-ohm loads to get the most out of the electrostatic panels.

Yes, the speakers feature custom 5-way bi-wire binding posts. These are designed to be tool-less, making it easy to connect your cables securely without needing a wrench or screwdriver.

Each speaker stands 44 inches tall and 9.2 inches wide. Because they utilize an open-back electrostatic design, they perform best when placed a few feet away from the front wall to allow the sound to radiate properly into your room.

The AirFrame Blade is an ultra-rigid structure that holds the electrostatic panel securely in place. By minimizing vibration and maximizing stability, it ensures that the panel remains perfectly positioned to deliver accurate, detailed sound.
