MW4-LCR 4" LCR In-Wall Speaker


One of the most compact in-wall speakers in MartinLogan history, the MW4-LCR expertly blends high performance and maximum flexibility. The MW4-LCR is a true “Left, Center, Right” speaker that can be used as a front, surround or center channel wherever high quality sound and a small footprint are desired.


  • The MartinLogan Sound
    Regardless of the environment, our speakers sound better, more articulate, detailed, and realistic. With Controlled Dispersion and one of the clearest tweeters in the industry, our architectural models can compete with and often exceed the performance of traditional speakers.

  • Controlled Dispersion
    Room acoustics are extremely important. Everything in the listening room has an impact on the sound of your speakers, so we try to minimize the harmful effects by focusing the sound directly on your ears. This increases clarity, and detail regardless of the rooms design.

  • Performance Meets Aesthetics
    While there are many choices of CI speakers out there, MartinLogan stands out for bringing unique, high-performance technologies together in a package that perfectly blends discrete sound with noticeable quality. Performance and Aesthetics, both without compromise.

  • Folded Motion Tweeter
    This miracle of audio engineering gives high efficiency and low distortion a new benchmark. Our signature Folded Motion Tweeter uses an extremely lightweight diaphragm, in a space saving “folded” design, to deliver incredible detail, speed, and accuracy in a small space.

  • Fiberglass Woofers
    All Motion CI speakers feature lightweight woven fiberglass cones specifically engineered for their application to blend seamlessly with the lightning speed of our signature Folded Motion Tweeter.
