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.

The Motion 20 is a breathtaking visual statement regardless
of its compact dimensions. Dual 5-1/2″ aluminum cone woofers are paired
with a rear-firing bass port for extra punch in the low frequencies. With the
addition of our Folded Motion tweeter it’s a design that delivers solid
low-frequency reinforcement, superb sound dispersion and precise, highly
dynamic high frequencies.

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.
