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.

Minimalistic Design Featuring Luxurious Real-Wood

Motion 30 combine high-excursion, black aluminum cone
woofers and low-turbulence, rear-firing bass ports, and features 5.5-inch
drivers paired with an advanced Folded Motion tweeter. Each model creates
clear, highly dynamic, and precise sound. Premium, five-way binding posts
assure a solid connection.

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.
