Know before you buy

The Focus ESL C18 is engineered to blend seamlessly with other MartinLogan electrostatic speakers. Its combination of an electrostatic transducer and Folded Motion tweeter ensures a consistent, immersive soundstage across your front soundstage.
The speaker is compatible with amplifiers rated for 4, 6, or 8 ohms. We recommend an amplifier capable of delivering between 50 and 400 watts per channel to ensure optimal performance and headroom.
The 18-inch XStat CLS electrostatic transducer provides exceptional clarity and detail, particularly in the mid-range. This design minimizes distortion and creates a more realistic, open sound profile than standard cone-based drivers.
Yes, you should adjust the On-Wall/Off-Wall acoustic contour switch located on the speaker. This setting compensates for the boundary effects caused by wall proximity, ensuring the bass and mid-range remain balanced regardless of placement.
The speaker is 43.2 inches wide. Depending on your mounting choice, the depth varies from 9.2 inches for table mounting up to 11.5 inches for angled wall installation, so ensure your furniture or wall space can support its 50-pound weight.
