Bookshelf speaker with a Folded Motion® tweeter and luscious
high-gloss finishes. Voice-matched with MartinLogan ESL speakers.
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.
High-Gloss Finishes
Motion 15 is available in three luxurious high-gloss
finishes; Piano Black, White or Black Cherrywood. The high-gloss black
cherrywood finish has deep cherry undertones and appears almost black in low
light, giving them a unique and understated elegance that blends into any
environment.
