Product Description

From the Manufacturer

Inspired by MartinLogan's ultra-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 our exquisite Folded Motion transducers with powerful, compact bass technology. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity. 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. Convenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. So simple, you'll actually enjoy hooking up these speakers.

5.0 out of 5 stars Spectacular speakers for the price, October 22, 2010

(What's this?)

The first impression of these speakers came as I unpacked them. The packaging is excellent as it should be to provide the proper protection. So, no surprise, they were delivered in perfect condition. These speakers are beautiful to look at and come with very classy baffles that connect magnetically to hid the speaker cones. Connecting them was very easy since they come with high quality connections that make it easy to make solidly connect with a variety of different kinds of wire connectors.

These speakers really deliver whether you are listening to Rock and Roll or classical music. My listing choices ranged from ELP's first album to Debussy's La Mer. Both kinds of music, even though wildly different, sounded great. You get the necessary powerful crunch needed to appreciate rock music, and when listening to classical music they very nicely reproduce subtle musical nuances required to fully appreciate the piece. They work very well for watching television or movies. My wife and I found the clarity to be excellent and made understanding vocals, and thus following conversations, easy.

I tested these speakers 3 different ways.

First, I tested them alone as a stereo pair. They seemed to disappear and the sound seems to come from the back wall. This is a great illusion that is a mark of high quality speakers! If you get out of the center sweet spot, the illusion dissipates somewhat but they still sound very good nevertheless. They were lacking a bit in the very lowest bass. For that reason, I would recommend coupling them with a nice sub-woofer for reproduction of frequencies below 60hz. This would probably only be noticeable with certain kinds of music played at fairly high volume levels.

Next, I tested them using a sub-woofer. This really helped get that powerful feeling that comes when these lower frequencies come into play. My subwoofer allows setting the frequency where it takes over and so I chose the 60hz. This worked great and I found that it was basically transparent as far as telling where the sound was coming from - which is a very good thing!

Finally, I tested them along with a center speaker and rear surrounds. All of my speakers were from the same manufacturer and were also of very high quality. When you get all of your speakers from the same vendor in the same speaker family, the good ones are matched with regard to the tone; or overall sound. As a result, properly setup, they can sound almost like a single large speaker that envelopes you. Replacing the two front speakers with these lost that illusion some, but in my opinion, still managed to improve the overall sound quality! The sound seems more accurate, crisp, and powerful! I love it!

That said, from this point on, since the main way I listen to my audio/video system is via a 5.1 surround setup, my remaining comments will be based on that listening experience.

It is very important to understand that the sound that is eventually delivered to your ears is not totally dependent on the speakers themselves. Equally important is the placement of the speakers and the acoustics of the room in which you are doing your listening. Working within the confines and shape of my living room, I placed the speakers 10 inches from the back wall and 7.5 feet apart from each other. My flooring is wood laminate so I didn't use the MiniETC spikes (which are a very nice touch if you are installing on carpet) that were included; instead I chose to use the pre-installed rubber feet. I have absolutely no doubt that these speakers could sound even better of I had different room size and acoustics to work with.

For my listening tests I chose some of my favorite pieces of music and those that I consider to be of the highest quality. Using high a high quality source is extremely important for testing speaker quality. The reason is that if you are testing $5000 speakers using an mp3 recorded at a bit rate of 128kbs, you may as well be listening to a pair of $500 speakers, The more expensive may sound slightly better, but the source itself would limit what the speakers are capable of producing. So, for starters, I have long considered "Emerson, Lake, & Palmer's" first album to be a great way to test any kind of audio gear; partly because of my familiarity with it, and because it is sonically spectacular. I found the experience to be spectacular. In my younger days, I owned Bose 901's, and have always considered them to be the best stereo speakers I have ever heard. These sounded as good and in my humble opinion, that is really saying a lot! Listening is a joy! In all fairness however, the Bose were all by themselves as a speaker pair and I'm listening to these as part of a 5.1 surround system. I can tell you that the sound is definitely an improvement over my previous main speakers. I really wanted to blast these up to ear-shattering levels, but alas, I share walls with 2 neighbors... For a short time however, I did approach that volume and it sounded sweeeeet!

Next up, I chose to listen to an SACD by "Porcupine Tree" titled "In Absentia". This sounded fantastic using my previous speakers. So good in fact that I found it hard to believe it could sound any better but - wow - the Martin Logan's sound even better - amazing.! The power and clarity is almost overwhelming. By the way, I can't recommend this album any more highly. It is one of my favorites in my entire collection.

For one of my classical music listening tests, I chose a piece by Debussy called "La Mer" that was recorded in DTS Surround. Again, I found these speakers to be quite excellent! I could easily hear all kinds of subtleties and make out the individual instruments. Shutting my eyes, I could easily imagine being seated at a live performance. It doesn't get much better than that. Other pieces I listened to were very convincing at reproducing the nuances of the violin and piano.

Not forgetting that an important part of today's home theater system is watching movies and television, I also checked out a few movies and again found that these speakers really deliver. For example, I put in a DVD of "The War of the Worlds" starring Tom Cruise. I jumped to the part where the lightning strikes start happening (close to the beginning of the movie) and was wowed by the awesome power and clarity. Continuing to watch the next 10 minutes of the movie it just sounded great. In fact, everything I've listened to on these sound great. They can definitely deliver crunch and power but still allow voices to be easily heard and understood.

My wife was skeptical about their size but she too has decided she loves these speakers. In most ways she was perfectly happy with our previous setup but what really impressed her the most was how much easier it is to understand dialogs when watching a movie. While she agrees that listening to music sounds even better, that's what really makes her the most happy.

I have listened to other, lesser quality, speakers in the past and find that after an hour or two, I experience what has been called listening fatigue. I think this is because your brain has to work harder to process less than perfect sound. That is clearly not the case with these. I was still immensely enjoying these even after having them on for several hours.

Overall, the words that come to mind to describe the sound these speakers produce are: powerful, controlled, accurate, crisp, tight, solid... For the money, one would be hard pressed to find speakers as good as these. These speakers are well worth considering for anyone who really cares about getting the best sound in the under $3000 price range.

5.0 out of 5 stars Excellent Reproduction for Stereo listening! (and Home Theater as part of a larger system), November 3, 2010

This review is from: MartinLogan Motion 12 Floorstanding Speaker (Black Ash, each) (Electronics)

(What's this?)

These speakers are GREAT! Please read on to discover just WHY I think so......

First, some background and setup info that might come in handy.....

The Martin Logan Motion 12 Floor-standing Speaker belongs to a family of products comprising Martin Logan's "Motion" line and is at the top tier of the Motion series. A pair of these speakers can be used for stereo listening or matched with other members of the Motion line to assemble a full 5.1 home theater system or even more elaborate configurations. All of the Motion line are 'Voice Matched' to provide a seamless tonal and spacial transition between speakers during 5.1 playback.

The speakers come very well packed and fully protected for shipping and include the miniETC floor spikes and detachable magnetic grills, upper and lower for each speaker, manual and warranty card. I was VERY impressed with the packing method used and they emerged from their boxes in absolute pristine condition, wrapped in their own cloth slip cover. Attaching the grills is literally a snap and foolproof.

The speakers themselves are nicely made and exude an air of quality as you might well expect from something of this price. They are heavy enough at 36 pounds not to tip over accidentally and stylish enough to fit into almost any home decor. The black ash wood veneer is real, not plastic. The speaker connections are handled by a push/pull spring loaded terminal but a small removable plastic cover reveals accommodation for a banana plug connection. Finding a place to safely lift the speakers without damaging the grills or speakers themselves is a bit tricky. I found that putting my hand in the rear port and tipping them into my other hand on the front of the top grill seemed safe and easiest since there are no handles or edges that easily lend themselves to moving these things.

Standing almost 43 inches high with a depth of 14 inches, these speakers are substantial. Thought must be given to their proper placement. They are rear ported and therefore should not be placed directly against a wall. As every room is different, experimenting with a number of positions could be beneficial. The included manual will give you some ideas on this.

The Motion 12's feature Martin Logan's proprietary 'Folded Motion Tweeter' , a dipole style 5.25 inch Mid Range driver that sends out sound both front and back and dual 6.5 inch woofers in a rear ported tuned enclosure.

It also should be said that these speakers (and most others) will benefit greatly from some 'burn in' time. Perhaps 72 hours or so at a volume of 90db using a variety of program material should loosen up the stiffness of the materials and allow the drivers to breathe a bit more effortlessly, thus focusing the sound, increasing the bass response and smoothing over any rough edges that may stick out when first powered up. I would not recommend any critical listening with these speakers until after at least 3 or 4 days of continuous 'burn in' . At that point they will sound wonderful and actually get better over time before reaching their audio peak. Straight from the box they are most impressive but will become so much more so after the burn in. Just something to consider before judging the Motion 12's. The speakers are rated at 150 Watts RMS and have a very respectable 92db sensitivity rating.

Finally, bear in mind that while the Motion 12's are advertised as "8 ohm compatible" the true impedance of these speakers is 4 ohms and as such they will greatly benefit from an amplifier that includes 4 ohms in their power rating specs. While it is true you can use a run of the mill AV receiver to power the Motion 12's, any prolonged use at high volume could put a strain on your amp and could cause overheating. Also, an amp rated for 4 ohm operation will provide much more musical headroom and will give these speakers a chance to truly shine and deliver the goods. I purchased a Harmon Kardon HK 3490 Stereo amp/receiver strictly for use with these speakers and that modest investment has paid off well in allowing the Motion 12's to sound their very best while providing them with 150 watts to both channels driven at 4 ohms. I initially tried the Motion 12's with my mid level Denon AVR and the difference between the two amps for use with these speakers is truly night and day.

I currently use a very nice mid priced 5.1 speaker system with sub that I am quite happy with, but always felt that home theater was that brand of speakers forte and that they were severely lacking for 2 channel music reproduction. I was very excited to burn in the Motion 12's, then get down to some serious testing and listening and see how much improvement I would notice between the Martin Logan's and my current 5.1 setup when playing strictly stereo program material. I used a Marantz CD player with good converters for CD playback and my Oppo BDP-83 for SACD and DVD-A playback.

ON to the testing....

The first difference I noticed between my old speakers and the Martin Logan's was the immense sound stage. I truly felt enveloped by the sound and after 'toeing in' the speakers I found the sweet spot and was really very aware of the superior stereo imaging the 12's provided. Wanting the most from these speakers I actually measured the distance between myself sitting in my preferred listening position and the speakers, sitting the same distance away from the speakers as they were from each other and forming a perfect triangle. This allowed the stereo image to magically appear. The Motion 12's stereo imaging is really a wonderful thing to listen to and enjoy. I was impressed!

The next thing I noticed were the immaculate tightly focused highs, almost crystalline in nature. My other setup relies on a horn type of technology and I had always found that a bit too harsh for music. Not so with the Martin Logan ' Folded Motion Tweeter' . This type of high frequency reproduction really shines and to my ears sounds quite natural. I had been using my Sennheiser 650 HD headphones for critical listening but always disliked the much storied 'sonic veil' that seemed to slightly diminish it's high end. With the Martin Logan Motion 12's that is never a problem. The decidedly non technical term of 'Clear as a Bell' comes to mind. Truly a musical tweeter and very unique to anything I have owned before.

On to the all important mid range.. In a word , BEAUTFUL! Going back again to my Sennheiser phones, I had always wished I could get as lush of a mid range from a speaker as I have got from both my 600's and 650's. That is no longer the case as the Motion 12's deliver this lushness in spades. Again, resorting to non tech terms, it is LUSH, rich and creamy and just dripping with mid ranged goodness. This is absolutely apparent when listening to music that features vocals. For my personal ultimate mid range acid test I used the Beatles Stereo remasters of both 'Revolver' and 'Magical Mystery Tour'. These are two albums I know inside and out and know exactly what they SHOULD sound like, having played them on numerous systems since they were released in the 60's. The vocals are EXACTLY where they should be, along with the electric guitars. My other reference recording to test mids is an obscure Toto album called Mindfields. In my humble opinion , it is one of the best engineered and mixed rock albums in my collection. It is also a record that I am on intimate terms with so I know what I expect to hear from it. Again, the Martin Logan Motion 12's totally satisfied my craving for Lush Mid Range satisfaction. At this point I would be totally impressed even without any bass response which is what I focused on next.

With two 6.5 woofers you are pushing a LOT of air. The depth of the cabinets increase towards the bottom of the enclosures and create a very nice space for the bass to emanate from. Also factor in the rear port and you get much more low end out of this speaker than you would have thought. Now days it seems many people are not satisfied listening to music without a ton of over exaggerated heavy bass. However, for MY musical listening needs, which consist mainly of older Classic rock and Pop rock heavy on vocals, Classical , and Jazz, these speakers are more than adequate for what I need in regard to bass response. The bass is tightly defined and the crossover is pretty much seamless, never stepping on any one part of the audio spectrum. The bass response is fast and with proper room placement you should get similar results. Make sure to try these speakers without using your 'loudness' control or artificially boosting the lows which may result in a smearing of the sound and low end in general.

Because these speakers were designed as part of a total SYSTEM I wondered what would happen if I connected my Klipsch front firing 12 inch powered sub woofer along with the Martin Logan's. Well, you certainly could FEEL it a lot more and yes the extension certainly went lower. And for movie/TV soundtracks it is probably preferable, but for plain old school 2 channel stereo listening to MY types of music, the Motion 12's all by themselves more than hold their own. I really do think a sub is optional and not mandatory! I am also quite sure many folks might disagree with that statement, but to each their own. I know precisely how I want my music to sound and Martin Logan Motion 12's deliver the goods without adding any artificial sounding subsonics to my classic rock recordings.

I am sure that an entire speaker system comprised of Martin Logan components would be simply amazing! I inserted them into my 5.1 system to see what difference they made and it was apparent I could easily replace my current speakers with Martin Logan's and it would be a noticeable... Read more ›

4.0 out of 5 stars Good for music, better for home theater, September 20, 2011

By

This review is from: MartinLogan Motion 12 Floorstanding Speaker (Black Ash, each) (Electronics)

Martin Logan Motion 12

I bought the M 12 after I realized that the ML Motion 10 cannot be used as a front/stereo speaker if you have some expectations from the sound in its price range. As soon as the double-boxed package containing the M 12 arrived, I set it up, and immediately noticed that the speakers I received - as opposed to the M 10s I had received 12 days before - may have been burnt in. The sound was as good as it gets from the technology employed in the speakers. The dust on the membranes suggested that this time received store display units. As I had a problem with one of the tweeters (the harmonica membrane was disfigured and the panel edges were touching each other at places), I called ML Customer Support. They got back to me in a few hours, and assured me that the speakers had not been used before, and the dust was from storage. The huge difference in sound quality between the M 10 and the M 12 apparently came from the design. Also, they told me they were sending me a replacement for the defective tweeter immediately. Great customer support!

The packaging is the sturdiest and safest I have ever seen in the music industry.

In my testing, I used a Harman-Kardon AVR 240 7.1 home theater receiver (60W/channel continuous in stereo, 50W/ch in 7.1 mode; other manufacturers indicate the peak that would destroy those amps after a second or two), Audioquest Type IV speaker wires, the M 10s for rear speakers, and a specially designed front that sonically happened to match the M 12 nearly perfectly (surprisingly, they were closer to the M 12 than the M 10 to the M 12). The room has next to no echo because of the furniture and the thick curtains. In order to avoid unwanted speared bass reproduction from the rear-firing bass port, I set up the front speakers about 3 ft from the rear wall. I tested the speakers both in 7.1 surround sound (primarily for movies) and in stereo (primarily for music). I use a Klipsch RW-10D as a subwoofer, and I am considering getting another in order to move more air as long as I can get another for the same $200 I paid for the first). After switching from 5.1 to 7.1, I noticed that a 7.1 setup is incomparably better than a 5.1 when it comes to the movie sound enveloping you.

The Motion 12 belongs to an entirely different universe than the Motion 10; in fact, I insist that the designers of the Motion 10 made a few basic irredeemable mistakes, the largest of which being the inclusion of two mid/bass drivers that restricts the Motion 10 to be a rear speaker in a home theater setup. Theoretically, the design could work in a large room from the distance where the midrange dispersion becomes negligible from 10-12 feet, but the membrane surface of the two mid/bass drivers would not work in an area exceeding 350-400 sq. feet. The good news is that I can use the M 10s as rear speakers with the M 12s, because they represent acceptably similar sound characteristics with the exception of less bass and inferior midrange.

One could call the M 12 the near-perfect design for a 3-way tower, but that does not mean the M 12 is without flaws. However, unless one insists on the lowest one and a half octave being present for music listening, the strengths outweigh the weaknesses.

The cabinet is solidly built; it widens towards the floor, so its mass center is relatively low, meaning it is not so easy to push over. However, there is a slight (less than 1mm) alignment discrepancy between the top (housing the tweeter and the midrange) and the bottom boxes (with the two woofers) of each of the two speakers, so the tweeter/midrange and the bass drivers are not firing in exactly the same direction. Apparently, a single bolt holds the two boxes together, and the alignment is easy to mess up by the turn of the nut when the two boxes are bolted together. After this experience, I simply cannot believe that the two boxes are properly separated and dampened. (The experience of replacing the damaged tweeter supported my suspicion: there is no dampening material under the tweeters. There is even some glue smeared unevenly on the surface the tweeter is sitting on. The internal wiring probably could not get any cheaper either. The only good part is that no soldering is required; the wires are equipped with slide-on connectors. Indeed, the plastic-housed terminals could not take much heat from the soldering iron.)
The two 6" woofers are placed low; while that, along with the asymmetrical design and the user-installable spikes, keeps resonance low too, I can easily imagine someone stepping into the lower one in the dark. Using the protective front cover can prevent such an accident. It is even fairly attractive. Sadly, at the same time, when they are on, they send my hearing on a wild goose chase looking for the sound. Terrible.

The midrange and the tweeter are in an open box from which the sound radiates in all directions and prevents boxy sound above 300Hz from the midrange/treble box. The lower box with the two woofers does not sound boxy either. Moreover, ML managed to avoid the loudness in the upper bass range that characterizes cheap speakers. Classical orchestral music sounds neutral; the M 12 does not emphasize any notes, although the polished sound and controlled bass of speakers that cost at least twice its price are missing. I still believe you get more than what you pay for if you go for the M 12 (assuming you can get a pair for $600 as I did).
The bass port is in the back, which makes the bass reproduction sensitive to the distance between the speaker and the wall (if you place them close to the wall, you get a bass boost for the price of boominess). The midrange and the tweeter are acceptably close to each other so that their distance does not smudge up the sound image (which happens on the M 10). The cheap-plastic-looking tweeter membrane calls for some distrust, but its only limitation comes from a weakening/uneven performance above 15kHz or so (ML claims its frequency response goes above 20KHz, but the chart I found on the net showed otherwise; besides, +-3dB actually means that the sound pressure (= volume) can vary at different frequencies by four times in intensity!!! ML claims these speakers go down to 40Hz; my hearing at the beginning suggested they started dropping around 60Hz or so. However, after about 150 hours of burn-in time, they perform fine. The 12dB/octave crossover hampers dynamics, but it switches at 300 and at 3000 Hz. 300 is as low as it tends to get, and the lower the better if you don't want to hear smeared human voices from your speakers. 3kHz is okay as long as the midrange does its job and the crossover manages to create an acceptable transition between the drivers. While 3kHz might be a bit high for the midrange (mostly because of its directionality), the folded tweeters of the M 12 (the same tweeter can be found in the M 10) simply cannot go any lower without an embarrassing level of distortion (caused by the cheap material, which is actually remedied by the design). Distortion is not a problem with the paper diaphragms of the midrange. ML placed the midrange and the tweeter in the same evenly perforated box that radiates the sound towards the back too, which opens up the sound stage, and prevents boxy sound above 300Hz. I cannot fathom why anyone would use the dust covers that drastically dampen the sound, but I understand there are people who cannot hear the difference. The upper box is covered with some sort of black nylon mesh that is proving to be an effective dust collector.

Before purchasing, I took the time to compare the sound quality of the M 12 with a number of other speakers at BestBuy, and the M 12 seemed to be a matter of taste in its price range (about $860 per pair after tax). However, the next unquestionable step up, the B&W CM5, cost $1,500 (the CM5 is a large bookshelf speaker that still sounded better in a large room than the tower with the same speaker set retailing for the same price). For nearly three times the price I paid for the M 12, the CM5 offers a more polished sound (although the M12 midrange can occasionally beat the 2-way CM5), more powerful and more controlled bass, After the experience, I did not hesitate long to buy a pair of M 12s for $600 when they went on sale at Newegg. After my exceedingly frustrating experience with the M 10, I was somewhat concerned, but my worries turned out to have been mostly unsubstantiated. After a few months I noticed that the M10 cannot reproduce bass in movies, because some films send too much bass to the side and the rear speakers. Eventually, I had to cut the crossover for the M10 at 120Hz to prevent overloading (membrane damage or coil burnout).

The M 12 creates a large sound stage extending on the sides beyond the space between the speakers, although the treble/midrange drivers still require a slight toe-in. The sound dispersion is quite even, especially compared with the M 10, which I do not consider suitable for a front speaker. As the bass port is in the back, 2-3 feet between the speakers and the wall behind them prevents boomy/unpredictable bass response. Theoretically, the M 12 could work in a relatively large room of about 500 sq. feet. The drivers can take a lot of punishment, but despite the two low mid/bass drivers, the speakers are missing a few notes (at least half an octave) from the low end of FM that eliminates them from the group of speakers I would recommend for music. Using 10 gauge or thicker multithreaded speaker wires can improve on the bass response (the Audioquest Type IV I am using at the moment is solid core, which produces a bit less bass; this bass, however, is more controlled. I am going for the Type VI, which is a compromise between the Type IV and a 10-gauge Monster wire). Of course, a subwoofer can complete bass reproduction for your system even if that seems a...
