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.

The Motion 20 is a breathtaking visual statement regardless of its compact dimensions. Dual 5-1/2" aluminum cone woofers are paired with a rear-firing bass port for extra punch in the low frequencies. With the addition of our Folded Motion tweeter it's a design that delivers solid low-frequency reinforcement, superb sound dispersion and precise, highly dynamic high frequencies.


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 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."

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. "

Terrific for Music!
I've had my Motion 20's for a few weeks now, and they sound like they're broken in. When looking for speakers in the 1600 USD price range it was hard to find many reviews of the Motion 20's, but I was able to audition them at Audio Visions locally. I compared them with others I could hear locally, B&W, Paradigm, Monitor, Definitive, Revel, Golden Ear and a few more. All speakers in this price range sound good, but not all speakers in this price range look good, too. I had heard the Motion 20's first and then went on my months long search. After some time I mostly remembered how much I liked the looks of the Motion 20's, but the sound is more important. The Motion 20's were the shortest and narrowest of what I auditioned, and I wondered if they would be big enough for my 13X17X10 living room. It's an odd room with very little reflection. With the competition fresh in mind, I went back and checked out the Motion 20's again, thinking I'd probably have to go up to the 40's if I stayed with Martin Logan. I was wrong - the Motion 20's definitely hold their own and fill my room with well balanced, articulate sound. I listen to mostly guitar based Rock and don't watch movies with these. My sub is currently not hooked up. So far, I haven't missed the sub at all. I toed in the speakers slightly and they're about 15 inches from the back wall and over 2 feet away from any side wall. The bass is solid and has nice depth. It's not just a one note thump. The highs are just better than most of the competition. The Motion 20's play music louder without losing control and getting muddy or losing their soundstage than most speakers. I read somewhere that the Motion series was just a placeholder for Martin Logan. I can't disagree with this statement more. These sound different from the Electrostatic speakers. There are advantages and disadvantages to both designs and Martin Logan has certainly become a major player in both, which can only be good news for people looking for speakers. There's a Motion speaker for every sized room, and the Motion 20's are perfect for mine. I love the sound foremost, but the visual appeal really can't be overlooked. The Motion 20's are quite stunning to look at. A lot of speakers in this price range use flat black vinyl or just a big cloth sock as a cover. The soft corners and glossy black finish and the metal grills of the Motion 20's don't seem to call attention to themselves, but so far, when people have noticed them, they have to go up and look at them. The 1600 dollar a pair range is a lot for some of us, and the Motion 20's don't give up anything in terms of looks or sound. I couldn't be happier with this decision.

WOW
I have had a lot of great speakers but these are my first Martin Logan's. I've wanted a pair for years and I so glad I bought these. Amazing right out of the box. Using a Carver to run them and they respond very well even at low volume. The ribbon tweeter is so crisp and smooth at the same time, no shrill highs. And the bass from these is well amazing, you'd swear there is a sub hooked up to them. If you want value and great sound these are for you. Dave

Motion 20 speakers....Very Pleased!
After upgrading my TV, I was going to replace my large, 20+ year old Polk Aidio speakers with a higher end sound bar. I had all but handed over my credit card when I walked into the audio room. I listened to a variety of speakers including the Motion 40s. The 40s were above my price range, but, wow! Anyway, the sales person suggested the Motion 20s. They did not have any to demo, but, after listening to the 40s, I took a chance and bought the Motion 20s on faith. I could not be more happy! I spent more money than I had planned and I'm glad I did. Sound bars are fine, but, nothing beats a nice pair of analog speakers. I new to Martin Logan, and am an instant fan. If you are considering the Motion series, don't hesitate. Pure quality.

Best of the Bunch
The Motion series speakers are a group that is underrated and over preforming. After continually comparing Motion 20's to other loud speakers in the same price range from other brands like B&W, Paradigm, Definitive Technology and even some pioneer elites. it was a 2 way battle. the B&W 683 S2 and the motion 20s. with a pricing difference of about 50 bucks price would no longer be considered. The 683's have a wide sound stage, well controlled and fairly deep bass, and are a pleasure to listen too. the major downfall here is the tweeter. the highs really suffered on female voices and some high pitched guitar solos. With the motion 20's the soundstage was equally as large as the B&W's the midrange faired as well as the bowers, but in no way better. the highs were airy, flowing, clean, and seemingly endless. the folded motion tweeter that ML developed puts the high frequency reproduction in the motion speakers above some speakers that are 10 times the cost. unfortunately for the motion 20 model at least, the bass lacked a solid "umph" which can break the immersion in 2 Channel music with a dynamic sway. after weighing out the pros and cons i quickly realized that you can always get bass from a subwoofer to compensate for the towers but you can't do much to improve the highs. Motion 20 is the winner. and I would buy them again and again.
