Inspired by MartinLogan's high-end electrostatic loudspeakers, the Motion Series was created to provide stunning sound for your ultimate-performance home theater or stereo. MartinLogan's dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends their exquisite Folded Motion transducers with powerful, compact bass technology. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.

Focusing on clarity and detail as MartinLogan's other high-end electrostatic loudspeakers, Motion 8 features an exquisite Folded Motion tweeter and powerful bass technology in a compact and affordable package. Key to Motion 8’s performance is the lightning fast response of the tweeter’s light-weight diaphragm combined with a large surface area (8-times that of a typical one-inch dome tweeter) which together achieve a smooth, refined sound with stunning dynamic range and jaw-dropping clarity - certain to inspire envy in audiophiles and non-audiophiles alike.

  • newegg Curve Appeal Complementing Motion's sonic accuracy is elegant yet understated styling. Flawless high-gloss, piano black finishes and subtle curves, along with MartinLogan’s signature perforated grille, give Motion 8 an elegant and timeless look.
  • newegg Folded Motion Tweeter The Folded Motion Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90% less excursion than the typical 1" 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.
  • newegg Premium Components Featuring dual 4-inch woofers, paper cones doped for stability and damping, and rigid structure dust cap, precision Vojtko crossover with custom air core coil and low DCR steel laminate inductors, and polyester film and low DF electrolytic capacitors, the Motion 8 speakers delivers clear, highly dynamic and precise sound.
  • newegg Flexible Installation Easy-to-install wall mount brackets allow for both horizontal and vertical on-wall installation to meet your various listening needs.
  • newegg Effortless Connection Convenient push-style binding posts take the frustration out of cable connection and easily adapt to accept banana plugs.

5 out of 5 eggsFantastic Speakers

Pros: "Folded Motion Tweeter" (an Air Motion Transformer) is, to my ears, one of the more phenomenal tweeters I have heard. It gives you clean, clear reproduction of high frequencies without giving that overly-crisp, overly harsh sound that you get out of many other tweeters on speakers. The rest of the speaker is pretty nice too, but I can think of nothing about this that is plain about it.

Good sound. Good vocals. If you want decent left/right speakers, theses are solid and they would be great as a Center channel (which is more or less what it was designed for).

It's also nice that you can get away with giving it less power than some of the other audiophile class speakers. But keep in mind if you put a horribly cheap amp on this you will probably get distortion just like with any other speaker. Your system is only as good as your weakest link.

Cons: Price? But it's really not a bad price for the amount of clarity that you get from it.

Other Thoughts: I thought that I needed to chime in because Martin Logan is a phenomenal company who make great sounding speakers even at entry level (for an audiophile) prices. I have talked with several people who have had nothing but great things to say about how Martin Logan treats their customers and handles warranty claims. I own several of their speakers and plan to own several more.
