What customers say
Customers overwhelmingly praise the Martin Logan Expression ESL 13A for its electrostatic transparency and vast, precise soundstage, delivering unparalleled realism, especially with vocals. A key highlight is the seamless integration of the powered woofer system, producing deep, fast bass that blends perfectly with the panel. The inclusion of Anthem Room Correction is frequently cited as crucial for optimizing performance across different room acoustics. While the design is visually appealing, the primary considerations are the substantial cost and the necessity for careful setup and high quality associated components to fully realize the speaker's reference level potential. Owners consider this a transformative, long-term investment in superior audio.
Know before you buy
Unlike traditional speakers, this model uses a large electrostatic panel that radiates sound from both the front and back. This dipole design creates a more open, spacious soundstage that feels less like a speaker and more like a live performance.
This technology uses dual 10-inch woofers to minimize the 'bass boom' that often occurs when speakers are placed near walls. By controlling how low frequencies interact with your room, it delivers tighter, more accurate bass that doesn't muddy the sound.
While the speakers will function without it, using ARC is highly recommended. It measures your room's unique acoustics and adjusts the DSP to ensure the bass response is balanced and clear, regardless of your room's shape or furniture placement.
Not at all. Because the Expression ESL 13A features built-in 300-watt Class-D amplifiers for the woofers, your external amplifier only needs to power the electrostatic panel. This makes them much easier to drive than many other high-end speakers.
Because they are dipole speakers that radiate sound from the rear, they perform best when placed at least a few feet away from the front wall. This distance allows the rear-firing sound to develop properly, creating the signature depth and transparency MartinLogan is known for.
Electrostatic panels are relatively low-maintenance, but they should be kept free of dust to maintain peak performance. A gentle vacuuming with a soft brush attachment or a light dusting with a microfiber cloth is usually sufficient to keep the panels clean.
