Motion® i Compact Speakers

Inspired by the clarity and detail of MartinLogan’s ultra-high-end electrostatic loudspeakers, Motion 2i, 4i, 6i, and 8i feature exquisite Folded Motion tweeters and powerful bass technology in compact and affordable packages.

Curve Appeal

Complementing Motion's sonic accuracy is elegant yet understated styling. Flawless high-gloss, piano black finishes and subtle curves, along with our signature perforated grille, give Motion Series speakers an elegant and timeless look. Tower models feature a real-wood veneer finish and a stylish aesthetic certain to blend with any decor.

The curves also serve a purpose; they allow Motion compact bookshelves to mount at two different angles with the included wall bracket (or with aftermarket using 1/4 x 20" threaded insert). This means you can point sound directly toward the desired listening area for high or low wall mounting applications. Beauty and brains!

Hook-Ups, Simplified.

Motion 4 speakers feature convenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. So simple, you'll actually enjoy hooking up these speakers.

Folded Motion™ Cascading Bass Port

MartinLogan engineers were faced with a daunting task—create a compact speaker with low-end bass reproduction found in speakers much, much larger. After many sleepless night and a myriad of prototypes, they created the Folded Motion Cascading Bass Port. This brilliant solution allows a long tuned port, which is folded over itself (think of a trombone's tuning arm) to be compacted and squeezed into the Motion 4. The result is amazingly detailed low bass that can play at high volumes with minimum distortion—all thanks to the elegantly simple cascading fold that slows down and controls the air motion of the bass waves.
