Summary
The entry-level model in MartinLogan’s Masterpiece series, the Classic ESL 9 brings the high-end experience of electrostatic speakers to a more compact enclosure. If you are shopping for a unique hi-fi experience, the Classic ESL 9 is guaranteed to delight.
In detail
MartinLogan’s ElectroMotion series brings the magic of electrostatics to a wider audience, thanks to its affordable price points. While there is no denying the value of those models, the Masterpiece series elevates your audiophile game to an entirely new plane.
The Classic ESL 9 is the entry-level model in this series. It will most often be compared to the ElectroMotion ESL X and it is clear that, in every regard, the Classic ESL 9 is superior. The larger electrostatic panel offers not only a grander presentation but also greater sense of effortlessness. The dual-woofer configuration also adds heft and authority to the bass performance of the speaker. From top to bottom, the Classic ESL 9 is a true Masterpiece.
Key Features
9” CLS XStat electrostatic panel.
Dual 8” woofers in balanced array.
Technology
The Curvilinear Line Source (CLS) XStat electrostatic panel is at the heart of every MartinLogan electrostatic design. The gentle curve of the panel allows for a wider dispersion of sound. MartinLogan’s Advanced MicroPerf stator technology exposes almost twice the diaphragm area of the electrostatic panel when compared to a traditional panel of the same size. The panels are joined to the speaker cabinet with MartinLogan’s ultra-rigid AirFrame Blade construction using aerospace-grade extruded aluminum alloy. Without obstructing the radiating area of the electrostatic speaker, it ensures rigid mounting the bass cabinet of the speaker.
To match the performance of the electrostatic panel, the Classic ESL 9 features a pair of high-excursion 8-inch laser-engineered aluminum cone woofers. The drivers are balanced using an opposing array: one faces forward, one faces to the back. The effect is to dramatically reduce cabinet resonances, maintaining clarity in the bass frequencies. The rear woofer has been tuned to minimize rear-wall interactions and a flared rear port improves efficiency and extends bass extension without distortion.

Sound Advice
The MartinLogan Classic ESL 9 will sound great right out of the box, but will sound its best after 100 hours of use when the drivers have had the opportunity to break in.
It is recommended that the back of the bass cabinet be no closer than 8” to the wall behind it. For best results, we recommend 15-24”.
