Motion MC4

The most compact in-ceiling speaker in the MartinLogan Motion series; the MC4 is also one of the most versatile. The stunning clarity of its Folded Motion Tweeter paired with a lightweight woven fiberglass woofer all wrapped 
up in a built-in enclosure means you get incredible, and predictable sound exactly where you want it. Perfectly 
suited for a whole house music system, a dedicated home theater or even as a low-profile height effect channel, 
the MC4 is a fantastic all-around performer.
