MartinLogan may be known for their innovative electrostatic speakers. But they know a few things about more conventional designs, too. Their Motion 40 speaker is proof, offering sublime high-end detail, smooth midrange accuracy, and deep bass extension. These beautiful speakers offer wide-open sound that seems to breathe with clarity and depth. The Motion series caught our attention when MartinLogan played them for us at a recent demonstration. We're anxious to hear more from the Motion 40. A lot more.
Perched above the Motion 40's midrange woofer is the source of this speaker's impressive high-frequency performance — MartinLogan's innovative Folded Motion tweeter. Its pleated diaphragm works similarly to an accordion by "squeezing" air to create sound. Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time is drastically reduced along with distortion. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage.
The Motion 40 speakers excel at delivering airy high-end detail.
Glorious high-end transparency is just part of the Motion 40's story. A 5-1/2" woofer keeps those crucial midrange frequencies warm and neutral, so vocals sound almost as if the singer were in the room. What about the bass? Two 6-1/2" woofers ensure the Motion 40 goes plenty low. These oversized drivers increase low-frequency output, making sure bass response isn't an afterthought or left for a subwoofer to worry about. The rear-firing bass port helps efficiently enhance bass response without adding distortion to this speaker's clean performance.
MartinLogan knows how to catch ears and eyes. The Motion 40 comes in your choice of Gloss Black or Black Cherrywood finishes. The cabinet features an angled top and soft corners, making it stand out from the typical box-shaped tower speaker. Removable spiked feet offer stability while preserving this speaker's natural sound.
Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.
Started using ESL's in 1964, Quad, Maggie's, and Martin Logan, and more. These are the first speakers to beat ESL's. These speakers are accurate, detailed, and when you close your eyes, you are There, at a live concert! Small light, gorgeous cherry wood cabinet, 4 feet tall and seamless integration with 2 Rel subwoofers, and Motion 15's
Pros: Sound, small size, cabinet, accuracy
Amazing! Bought a pair of ML40's with an ML30 center channel, Dynamo 1000 sub and Motion 4 rears and am literally blown away. I've never been much of a real music enthusiast, nor a real moviegoer, but these speakers have completely changed my appreciation for both. The sound is so full, clear and clean that I've been completely pulled in! It seems every music track I listen to I'm hearing little dialogue or instruments I've never heard before! They're in a great room that is right off an open concept kitchen. The combined space is 38x25 with a sloped ceiling 8' to 17' so I had real concerns about sound. This setup is nothing short of spectacular in my opinion. I hiccuped with ordering the wrong color (the cherry is pretty darn red) so much, much thanks to Crutchfield for accepting the return without question.
Pros: Beautiful speakers very well crafted. Such great crisp clean sound over a full range. Bass for music is very adequately (and primarily) driven out of the 40 speakers with some supplemental sub rounding it off.
Beautiful speakers and great sound. Still in break-in period.
Pros: Finish and construction, sound.
Cons: none so far
I bought these speakers to upgrade from Infinity Primus. While the Primus were a good value for the price, the Motion 40's are a definite step up. They really perform well when cranking up the volume compared to the Primus. Nice low end, really do not feel the need to have subwoofer when playing music. I like the bright and detailed sound from the tweeters. They look really nice with smaller foot print (wife friendly). I looked at the ESLs but did not appreciate enough improvement in sound for the price. I looked at the B&W CMs but liked the sound and look of the 40's better as well as the lower price tag. Wife was initially leery of the price but ended up really liking them too.
Pros: Sound great, look great
Stepped up from B&W bookshelf speakers and I've been extremely pleased with the Motion40's. The sound quality is dynamic and they look very nice as well. These are without a doubt the best speakers I've ever owned.
Pros: Nice, wide and detailed sound field. Best tweeters I've ever heard.
Cons: They make me want to stay in my music room too much.
The appearance and sound quality of these speakers is outstanding.
Pros: Excellent appearance, Excellent sound.
Cons: 72 hr. @ 92 db break in period. However, It's a requirement one can live with
Very nice sounding and looking speakers
I'm giving these a 5 because they honestly sound really good. I originally bought the instead of the ESL's because I heard the ESL's are finicky. While the motion 40 are really good, and I would recommend them to anyone considering a traditional speaker at this price, I now recommend the ESL's.
Pros: Great sound.
Cons: None, but they have a better bigger brother
I have never heard speakers that sound this good. Words cannot describe how realistic they sound. I feel like I'm in the recording booth with the artists. I believe I still have a ways to go until the are completely broken in. Well worth the money.
Pros: The most amazing speakers I have ever owned.

3-Way Tower Loudspeaker: The MartinLogan Motion 40 tower loudspeaker employs a 3-way speaker design and features MartinLogan's advanced resolution Folded Motion Tweeter, a 5.5" aluminum cone midrange driver, and two 6.5" aluminum cone bass woofers. Pairing these trio of woofers together with the Folded Motion Tweeter creates a dynamic full-range sound with an expansive soundstage.
Precision Vojtko Crossovers: To seamlessly blend the audio output from the Folded Motion Tweeter, 5.5" midrange driver, and dual 6.5" bass woofers, the Motion 40 tower speaker features two precision Vojtko crossovers (500/2,600Hz) utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.
Bi-Wirable Binding Post: The MartinLogan Motion 40 features bi-wirable binding posts and provide the ultimate level of flexibility for connection and setup. MartinLogan's proprietary tool-less binding posts simplify cable connection and management. Two sets are supplied; one connected to the tweeter and midrange, while the other is connected to the dual woofers. You can choose to bi-wire/bi-amp the Motion 40 loudspeaker, or use jumper clips between the binding post sets for a single wire-connection. The binding posts will accept bare wire (16- to 8-gauge), pin-connectors, spade-connectors, and banana plugs (single only).
High-Gloss Cabinet: Complementing the Motion 40 loudspeaker's sonic accuracy is its elegant, yet understated styling. A high-gloss, piano black or black cherrywood finish, along with MartinLogan's signature perforated grille, give the Motion 40 speaker an elegant and timeless look that will blend into almost any decor.
Interchangeable Feet: The MartinLogan Motion 40 tower loudspeaker includes four pre-installed rubber feet for tile and hardwood floors. You can replace the pre-installed rubber feet with four metal spiked feet for carpeted flooring. Both the rubber and spiked feet are threaded so they can be adjusted to non-level floors. The spiked feed add approximately 0.875" to the height of the speaker.
Placement: Although the speakers are designed to deliver a superb sonic performance when placed close to a wall, you may notice improved imaging and detail if you are able to place the speakers (measured from the tweeter and woofers) 2' to 3' from the front wall and 2' or more from the side walls. To achieve optimum stereo imaging it is recommend that you aim the speakers toward your primary listening position.
Break-in Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.
Listen to them and they sounded great. Great reviews too... [ Keith Dec 27, 2015 ]
I've had the Martin Logan Motion 40's for about 7 months and I spent the time breaking them in per ML recommendation. My current setup is a Marantz integrated amp 7005, Marantz CD 6005 and a Pro-Ject Carbon turntable. My listening space is in my attic, somewhat small, carpeted with a pitch ceiling. The speakers are around 9' apart and roughly the same distance to my typical listening position. I've spent a fair amount of time playing with the positioning of the speakers relative to my seating position and each speaker's relation to side and back wall. Incrementally moving them does make a difference and, yes, I think there is a sweet spot, but that is intentional on my part as I've set them up to be at their best where I typically sit. At the same time the speakers put up a big sound image in my space and I don't feel that when I'm casually listening and just want some music going while I work that there is any issue with sound. They still sound great walking around the room. I've come back to the Hi-Fi world after many years listening to bad music via surround sound. I used to have a set of Magnaplaners and understand your imaging concern. The ML's sound great and for the money and my use I think they're a great buy. [ RICHARD Feb 02, 2016 ]
Nope. I returned the electrostats for that reason. [ BERVICK Feb 02, 2016 ]
I think the sweet spot will always be optimal, but the Motion series seems to be more forgiving than the Electrostats. I have 3 theater recliners, the center is always the best, but the outside seats have good sound as well, just not quite as good imaging as center. [ Matthew Feb 02, 2016 ]
No, not at all... I have mine in a tight spot about 10"-12" from the wall in a smaller room and they sound amazing. I wouldn't worry too much about placement. [ wesley Feb 01, 2016 ]
They do not. They have a fairly wide dispersion angle, unlike the ESLs. Great speakers. [ DANIEL Feb 01, 2016 ]
less so, I think. [ Eric Feb 01, 2016 ]
NOt as much as electrostatics much better dispersion [ Branko Feb 01, 2016 ]
I do not know what comparison you are making. Every 'stereo' (2 channel system) has a 'sweet spot'. so this thing does. It also depends your room structure and size since you hear reflections too. [ INTAE Feb 01, 2016 ]
the company recommends placement and there is a sweet spot; however: I did not follow their recommendations and they still sound fantastic. [ Dominick Feb 01, 2016 ]
With the folded motion tweeter you get a ton of highs, but it certainly isn't harsh by any means. I haven't listen to these without my ML Dynamo 700 subwoofer so I can't comment on the bass, but there doesn't seem to be any frequencies lacking. The key to good bass with these is being able to pull them 1.5-2 feet off the front wall as they are rear ported. The biggest improvement I saw with these is the soundstage. It's huge! Watching movies it sounds like things are 4 feet beyond the speaker, and the speakers really melt away. Worth the price is going to be highly subjective. I'm quite happy with them personally, but I was also able to demo them locally before purchasing here. [ Matthew Aug 28, 2014 ]
Speakers have very sharp crisp highs. I think they sounded sharper than the more expensive electrostatic models. They also have excellent bass. If you want serious chest pounding bass that will shake the floorboards you will probably want to consider a subwoofer still. I think the speakers are well worth the price. I did quite a bit of demoing before I chose these. Hope this helps in your decision. [ Erik Aug 28, 2014 ]
