“A pretty face and practical too – what’s not to like?… We really [like] the Motion 15s. Their delicate, detailed and agile performance impresses us, and they’re great fun to listen to.” — What Hi-Fi?

“The Folded Motion Tweeter, perforated metal grill, and over sound quality are evidence of this balance. Martin Logan seems to have hit a nice balance with the [Motion 15s], the first speakers of their kind from Martin Logan, there is a lot to like here. If you really want the sound of Martin Logan’s electrostats, but want something in a smaller form factor, then look no further, go out and buy a pair of these. If you are starting to build a 2.1 or 5.1 system, the [Motion 15s] are at least worth a good listen. “ — Cliff Heyne, Audioholics

“…a strong and vibrant well staged sound, with crisp and controlled treble married to a strong stable midrange – for their price and size they do a remarkable job and have a sheer enthusiasm for instruments and vocals rather than punchier electronica. They won’t ever get caught in a speed trap, but the top-end has great pace and the bottom-end doesn’t lag behind or ever seem slow, balancing nicely for a more natural presentation. Overall characterisation is slightly smooth, un-offensive and particularly pleasing in a smaller sized room. The design and finish is great and the included grills protect the delicate ribbon from little hands and is also non-offensive or detrimental to the sound.” — Dan Worth, HiFi Pig

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.
