Our Review

MartinLogan ElectroMotion ESL C Electrostatic Center Speaker - Gloss Black Review


A center channel speaker is the cornerstone of a home theater audio system, anchoring dialogue and on-screen action directly to the picture for a cohesive audiovisual experience. MartinLogan, a brand synonymous with high-fidelity sound, has long been a pioneer in electrostatic speaker technology. Their ElectroMotion ESL C is a testament to their commitment to audio excellence, promising a transformative listening experience for the discerning audiophile.

Design and Build


The MartinLogan ElectroMotion ESL C's gloss black finish exudes elegance and sophistication, easily becoming the focal point of any home theater setup. However, the speaker's 23-inch width may pose a challenge for those with limited space, necessitating a thoughtful rearrangement of components to accommodate its presence.

Construction Quality

The build quality of the ElectroMotion ESL C is beyond reproach, with a robust construction that speaks to MartinLogan's attention to detail. The high-quality binding posts ensure secure and high-performance wire connections, a subtle but critical feature for maintaining signal integrity.


Advanced Electrostatic Technology

At the heart of the ESL C is the XStat CLS electrostatic transducer, a hallmark of MartinLogan's design philosophy. This technology offers an unparalleled transient response and transparency, with the Folded Motion tweeter complementing it by contributing to a more nuanced and detailed high-frequency reproduction.

Acoustic Engineering

The CenterForce dual woofer system provides a well-integrated low-end, crucial for a center channel speaker. The ported cabinet design further enhances this by extending the bass response, ensuring that the speaker delivers a full-range performance that belies its size.

User Experience

Integrating the ESL C with other ElectroMotion Series speakers is straightforward, promising a seamless soundstage. However, the inclusion of an AC/DC adapter, while necessary for the electrostatic panel, may be seen as a con for those preferring a more traditional setup.


Sound Quality

The ESL C's frequency response and 89 dB sensitivity indicate a speaker capable of delivering a wide soundstage with clarity and precision. The recommended amplifier power range of 20-300 watts offers flexibility, allowing users to drive the speaker with a variety of amplifiers, from modest to powerful.

Electrostatic Speaker Characteristics

Electrostatic speakers are revered for their mid-range reproduction, and the ESL C is no exception. Its ability to render vocals and instrumental textures with lifelike realism is a significant draw. Nevertheless, listeners in certain environments may perceive the sound as overly bright, necessitating careful room treatment and setup.

Bass Response and Clarity

The low-frequency performance is commendable, with the CenterForce system producing a bass that is both deep and well-blended. The high-performance crossover network maintains a coherent sound across the frequency spectrum, ensuring that each note and dialogue is articulated with clarity.

Installation and Setup

Positioning Challenges

Achieving the optimal sound from the ESL C requires meticulous placement. Its electrostatic design is sensitive to room acoustics, and users will need to experiment with positioning to find the sweet spot that yields the best audio fidelity.

Compatibility and Integration

While designed to complement other ElectroMotion speakers, the ESL C may exhibit a slight timbral shift when paired with different towers or bookshelf speakers. Users should be prepared to fine-tune their systems to minimize these discrepancies.

Customer Feedback and Comparisons

Positive Reviews

The ESL C has garnered acclaim for its superior performance, with many users noting a significant improvement in their home theater's vocal clarity and overall soundstage when integrating this center channel.

Criticisms and Comparisons

Some criticisms include the speaker's large size and the necessity for regular maintenance of the gloss black finish. When compared to other high-end center channels, the ESL C holds its ground, particularly in its unique electrostatic qualities, though some may prefer the more conventional dynamic drivers for their warmth.

Final Thoughts

The MartinLogan ElectroMotion ESL C is a formidable center channel speaker that offers a remarkable blend of clarity, detail, and presence. Its electrostatic technology sets it apart from the competition, though this also introduces certain setup challenges. For those willing to invest the time in proper placement and pairing with compatible components, the ESL C will deliver an audio experience that is both immersive and exhilarating. Whether it's the right choice will depend on the user's commitment to achieving the optimal electrostatic sound and their willingness to accommodate its distinct design and setup requirements.
