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 elegant Motion 40 features an advanced resolution Folded
Motion tweeter, a 5-1/2″ aluminum cone midrange driver and dual
6-1/2″ aluminum cone woofers.

Part of the secret to the Motion 40’s outstanding
performance lies in the dual oversized black-aluminum cone woofers paired with
a rear-firing bass port. The oversized woofer design creates increased cone
area delivering higher output and audibly richer, deeper bass performance than
it’s slightly smaller sibling, the Motion 20. The addition of a dedicated
mid-woofer also promotes an even more open, revealing and authentic sound in
the critical midrange.

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.
