Engineering Genius  

What makes the Motion Series sound so amazing? MartinLogan's dedicated in-house engineering team started by utilizing and refining the most advanced, compact technologies and combining them with innovative engineering.  The result is an emotionally engaging sound that rivals (and most times trounces) traditional loudspeakers of similar size and price.  



Folded Motion® Tweeters  

The signature Folded Motion tweeters utilize extremely low mass diaphragms that "squeeze" air, and require significantly less excursion than the typical 1-inch dome tweeter, which drastically minimizes distortion while providing a lightning fast response time.  The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
