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.

Minimalistic Design Featuring Luxurious Real-Wood

Motion 30 combine high-excursion, black aluminum cone woofers and low-turbulence, rear-firing bass ports, and features 5.5-inch drivers paired with an advanced Folded Motion tweeter. Each model creates clear, highly dynamic, and precise sound. Premium, five-way binding posts assure a solid connection.

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.

MartinLogan Motion 40 and Motion 30 Review

"The thing I love most about the Motion 40s and Motion 30 in my surround how revealing they are, without being punishing... Amazingly, with even the most action-packed sequences, the Motion 30 never suffers due to its size, and in fact it holds its own with center channels way, way larger. Dialogue clarity is fantastic, integration with the rest of the system is simply superb, and dispersion is (almost) perfect... So needless to say, I love them, especially for the price."

MartinLogan Motion 40 Speaker System

"This system is so sublime and so thoroughly enthralling that it feels miserly to limit the description to super-premium. The MartinLogan Motion 40 system is one of those rare products that comes along in which every aspect construction, physical appearance, emotional appeal, etc. is so ideally matched in its expression to one another that the finished whole transcends the category that the parts would have normally put it in. This system has that special essence of completeness that’s extremely difficult to find at any price. Marvelous, MartinLogan. Absolutely marvelous."

MartinLogan’s ESL-X Show Why Electrostatic Loudspeakers are so Beloved

"While listening, it brought to mind what may be the best part of listening to the ESL-X speakers: They are forgiving enough to deliver the traits I’ve already mentioned, without sacrificing quality. What I mean by that is that is that some speakers sound good with classical music, others sound good with rock and pop. Throw anything at the ESL-X and I think they will deliver high levels of enjoyment that will make you forget that you are critically listening. Instead, you’ll simply want to bob your head like Angus Young or stomp your feet like Neil Young when cranking up the ESL-Xs."

MartinLogan Motion 4i and 8i Speakers

"If you’re not familiar with the original Motion Series speakers, their performance can best be summed up in two words: “detailed” and “dynamic.” Much like the originals, the amount of sound coming out of these little cabinets is a bit startling. "

MartinLogan Motion 20 Loudspeakers

"MartinLogan’s Motion 20 is a compelling option for anyone shopping for speakers in the range of $1500 to $2000/pair. It conveys music in a detailed manner, with pinpoint imaging and surprisingly powerful bass for its size. And while I generally preferred GoldenEar Technology’s more expensive Triton Five for classical music, the Motion 20 was in some ways the more versatile speaker -- and better equipped to rock out. If you want dynamic, extended sound from a compact floorstander, the MartinLogan Motion 20 can deliver it."

Motion 30 for center channel
About 3 months ago, I invested in a pair ML Motion 40s and the Dynamo 1000. I knew the center channel would be the next purchase as I needed something that would properly pair with the 40s. Well, I got my new Christmas present to myself in the Motion 30 and I'm loving it. Dialogue is crisper than ever and I can actually hear the characters speaking much better than before. Also, when I'm listening to music in 7 channel surround, I am enveloped in a room of sound. The staging is just phenomenal and I couldn't be happier. Yes, $700 is a lot to spend on a speaker, but remember most of your sound actually goes through the center channel! It's the most important speaker in your system! Highly recommend.

Very Pleased
I added the Motion 30 to my Motions 40's and Dynamo 500 system. It truly opens the sound stage and adds depth to the performance. Would recommend to anyone.

Love the clarity!!!
I have just added the Motion 30 to my system, which consists of Preface speakers and the Dynamo 700 subwoofer. It is a good fit. The Motion 30 is extremely clear in its sound delivery. The sound is very full, balanced and covers the spectrum. The Motion 30 is a very good looking speaker, very subtle, it does not need to jump out at you.
