MartinLogan Classic ESL 9 Electrostatic Floorstanding Speakers (Pair)

Timeless Design. Extraordinary Electrostatic Performance.

Experience the remarkable transparency, detail, and musical realism of the MartinLogan Classic ESL 9, a premium hybrid electrostatic floorstanding loudspeaker from MartinLogan's acclaimed Masterpiece Series.

Combining MartinLogan's legendary XStat CLS electrostatic technology with powerful dual 8-inch woofers, the Classic ESL 9 delivers an exceptionally open soundstage, natural vocals, precise imaging, and deep, articulate bass.

Its large curvilinear electrostatic panel reproduces music with breathtaking speed and clarity, revealing subtle details and textures that conventional loudspeakers can struggle to capture.

Electrostatic Precision Meets Powerful Bass

The Classic ESL 9 features a 44-inch XStat CLS electrostatic panel supported by MartinLogan's rigid AirFrame Blade construction.

Dual 8-inch aluminum-cone woofers, arranged in a carefully engineered cabinet, deliver impactful low-frequency performance while maintaining the speed and accuracy of the electrostatic panel.

A precision Vojtko crossover ensures seamless integration between the electrostatic and dynamic drivers.

The result is a speaker equally capable of reproducing intimate acoustic recordings, full-scale orchestral performances, and dynamic home theater soundtracks.
