Built-In Wireless Receiver offers Extreme Placement Flexibility!

Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience (not to mention unsightliness!) of running long lengths of cable through walls, along baseboards or under floors and carpets. To solve the problem, the Dynamo 700w incorporates a wireless receiver (digital RF transmission) for use with the included SWT-2 MartinLogan Subwoofer Wireless Transmitter in which case, cable clutter also becomes a moot point!

High-Resolution Low-Distortion 12-Inch Woofer

The Dynamo 700's advanced-technology driver pairs a high-power magnet structure with a 10-inch diaphragm to deliver huge excursion and sound output while perfectly preserving the tiniest bass detail... and all without a hint of distortion. The exceptional damping properties of the cone material also ensure the smooth, non-resonant response necessary for truly seamless blending with MartinLogan electrostatic panel and Folded Motion™ driver technologies.

Advanced Ultra-Efficient 300-Watt Amplifier

The Dynamo 700w's ultra-efficient high-power amplifier uses variable audio tracking power supplies to drive its class AB output stage. With lower distortion and less noise than typical Class D switching amplifiers this advanced design allows the amplifier to operate at much higher efficiencies than a typical class AB amplifier, delivering a true 300 watts of continuous power. An energy-conscious design, the Dynamo 700w's amp consumes less than a single watt in Standby mode.

Front-Firing or Down-Firing Configuration

To maximize performance when installed inside of a cabinet or other discrete installation, the Dynamo 700w's standard down-firing configuration easily converts into a front-firing orientation-no tools required! A grill cover and 90 degree RCA adaptors are provided for use in front-firing applications.

Inverse Mathematical Equalization (IME) Filter

An IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response - far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.

Sealed Cabinet with Extensive Internal Bracing

A good sealed system will typically exhibit less transient-blurring group delay while maintaining smooth, consistent response regardless of music or movie source material. On the outside, the Dynamo 700w's cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing acts an excellent baffle for the woofer while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.

Inverse Mathematical Equalization (IME) Filter

An IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response - far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.

Seamless System Integration - Engineered for Stereo and Home Theater

Comprehensive connection options, low-pass filtering and phase control make integrating the Dynamo 700w subwoofer into a multi-channel home theater or stereo music setup simple and seamless. The main left/right line-level inputs feed into a precision low-pass filter with a cut-off frequency variable from 35 to 120 Hz. For systems in which a surround processor supplies the crossover, the Dynamo 700w offers an LFE input that bypasses its internal filters.

Energy Transfer Coupler (ETC) Spikes

The Dynamo 700w comes with custom ETC spikes which can be used in place of the feet to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality.

MartinLogan ElectroMotion 5.1 loudspeaker review

"The depth and agility of the Dynamo sub is a joy to behold, too, providing a solid bass bed without overdoing it, but turn it off and you’ll find the EM-ESLs’ own woofers offer fantastic depth on their own. Throw the EM-C2’s wonderfully clear speech reproduction into the mix, which injects words with presence and subtle nuance, and you have a very accomplished performance."

Martin Logan Motion Vision Soundbar and Dynamo 700W Subwoofer

"MartinLogan’s Vision, especially when supported by the Dynamo 700w sub, makes a very worthy solution. It won’t produce the broad sound-stage of a “real” system, nor genuine surround sound ambience or effects. But it comes close enough, and its impressive accuracy and detail in the playback of voices and instruments warrant close listening — even by an audiophile."

MartinLogan ElectroMotion - Other Speakers Design and Performance

"This coherence is key to its success – the EM-C2, EM-FX2s and Dynamo all fuse tightly with no differences in tone, which is impressive considering how the electrostatic panels work in such a different way to the cones and Folded Motion tweeters used elsewhere... Insightful detail reproduction, authoritative speech, a seamlessly immersive soundstage, rock-solid bass, tight integration… you name it, this system excels at it."

Great Sub but be careful when using the wireless option.
I bought this impressive little sub a few years back and it rocks! It has tons of input/ouput flexibility and plenty of SPLs too. If I had the money I would get another one. I am a 2 channel audio guy mostly with a few movies now and then but mostly heavy metal and techno music. I only have 2 complaints, first the wireless LED doesn't ever stop blinking so I see it on the wall under my tv and then there is the wireless bass option. I wish I knew how to stop the LED from blinking, I guess I could just paint it black but disabling the wireless option would be better. Now, why don't I like the wireless option you ask, well I will say it does work fine but not how I had it setup on my ADCOM GTP450 tuner preamp's ext processor out. Sorry subwoofer options weren't invented yet. So I come home from work and I hear a very loud vibration coming from the general vacinity of my house. I can see my windows are vibrating so I think what the hell is that, I have to get in the house. As soon as I open the door I think oh god my poor old bird he's probably dead, theres no way he could survive this all day and what did people think as they passed by my house. I rush in with hands over my ears and body vibrating to rescue my audio system from a total meltdown to find my subwoofer has walked across the room as far as the power cord would let it go. The power cord connector was on its way to completely rubbing its way through the drywall when I turned it off. After a day of raw uncontrolled bass I knew the poor voice coil was fried so I covered my ears and reset the power to my audio system and braced for the horrible sound you never want to hear in a hifi sytem but it never came. There was just peace and quiet so I fired up a cd and everything sounded fine, and it still is today. I dodged a bullet. As far a I can piece together by the blinking clocks in the house was that the power at my house went out and the wireless link inputs just loved it so when the power returned it decided to go into some kind of crazy ground loop hum oscillation at my ADCOM preamp output which apparently are not relay isolated. When I reset the system in a controlled way the link worked fine but I removed it and hardwired it to the LFE input to be safe and no more problems. Final thought, because my ADCOM preamp was older its outputs were never intended to be connected to a wireless link which is always on and transmitting random noise when the preamp was off. I hope my next preamp has a subout. And yes, my bird (a male cockatiel) is still alive and untramatized at 29 years old.

Perfect Sub. Boom????
Put this into a family room with tall ceilings and about 20' x 20' and Wow.... this thing is great. Wasn't looking to break windows and I might be able to. I've got this on about 50% and it sounds great for music and movies. I can't imagine needing anything more it is very clean and responsive. I will look for more ML speakers in the future.

Manual Quality
The quality of the product is excellent. But the chapter regarding the Optional Wireless Connection is poor. It only says "connect a transmitter to your electronics"...It should say where and how to connect it as you are not going to use cables as shown in figs. 2 and 4, and identifying it is the actual transmitter you are receiving. Also the starting up conditions should be very clear: turn level to a minimum when first used. Also it could be helpfull to know in advance which are the lowest frequency responses for some of the Martin Logan speakers, as a table, to help during installation.

Great Sub!
I recently purchased a Yamaha YSP-5600 soundbar to replace a 5.1 speaker system to make better use of the space we have. I then decided I might as well upgrade my subwoofer and was looking for something with a small footprint and that was also wireless. After reading reviews and looking at different brands I decided on the Martin Logan Dynamo 700w. I was not familiar with their products but decided to go ahead with the purchase. After the initial shock of how small the sub was, I did not think that this was such a good idea. Wrong! This puts my old much larger ported sub to shame. The bass is tight and sounds great!

Perfect for Small - Medium spaces
I bought the Dynamo 700W just under a year ago, and it has really paired well with my setup. The bass is very precise, and clear. For music, I could not have asked for a better sub (I listen to a lot of Jazz). For movies, it has been more then enough. Obviously there are much louder subs on the market, and subs that will reach a lower frequency, but the "quality" of the bass this sub provides is tremendous. I will be adding a second 700w to my setup as soon as my wife allows.

Worthy of 6 star service!
It's one thing to design build and offer a quality product and quite another to stand by your products. A glitch in the wireless transmitter was replaced within 3 days of my initial call into service. Now that's service!

Great subwoofer!!!
The Dynamo 700w replaces a 15 year old Infinity SSW-10 subwoofer and completes my all-Martin Logan 5.1 channel home theater system (front Requests, center Cinema I and Surround Vignettes) Whether played in 5.1 or 2.1 mode, the bass and low level music is so much clearer and distinct now and I've had it only for 3 days and its not even broken in!!! Even in low volume you could hear the bass. And the Infinity is a servo subwoofer and is even larger than the Dynamo! Martin Logan speakers are really incredible!!! Everyone who listens to my ML speakers always say they are so clear and the music is like floating in the air!!! I can't believe the Dynamo is making such a big difference. Thanks ML for making such great products!!!

In the Pocket
Superb quality & finish, Top notch components and interface. This unit was integrated into HiFi using a Yamaha RX-A Series AV Receiver. After break-in and crossover tuning the soundscape is very smooth, with low-end frequencies revealing aural and physical effects previously unheard in the system. I will soon order the Motion 6 centre and 2 series surrounds to create a 5.1 system.

Well I have to say it looks good and feels good. My wireless set up was free it was included with my 1000, need I say you have to Pay For It with other Models “DEF TECH SUPER CUBE” and others but the Martin Logan Dynamo 1000 and my 700 do the BEST!

awesome
This tiny subs are awesome I bought two of them running them in stereo for music and theater. The bass is incredible. You can\'t tell the bass is coming from the subs, is like the front speakers morph with the subwoofers and give out one sound. Very musical and tight and accurate and loud too.

Martin Logan makes it happen!
Dear ML I have the ML CLS IIZ's and have had to deal with my Velodine's 18 sub to add just the little bump on the lower extension. In doing so, I have always had slow lumbering, bloated, muddy base and an audible 60 cycle hum that the support staff at Velodyne told me is within spec. for the 3,000 watt class D amp and nothing could be done to fix the problem. I'm am only telling this story not to slam Velodyne, but to show praise for Martin Logan. Yesterday, I auditioned a stereo pair of the Dynamo 500 subs in my sound room and found them to be quite a speaker for the money. Very nice sound shaping of the lower register. One problem was I still wasn't getting quite the low bass extension that I was looking for and the rear sound ports seamed to be a little bloated sounding. (Very little) In short I still need the Velodyne's help since it goes down to 18 hz. Today, I have just upgrade to the ML Dynamo 700's and I must say... "My quest has come to completion". Very tight, fast, base and not a sound of buzz or hum in the units. (Note: I even have them firing forward) Just beautiful black-black rich base. Great sound shape and low register extension. Finally I can retire the 18" buzzing mud maker. Thank you to ML and your design team. I can only imagine the work that went into pulling this small wonder off. My short term plan is to now stack 4 of these on each side of my CLS IIz's and create a vertical bank of bass for the left and right side. (Something like your Statement speaker) I just have to work out a coupling rack so that they can be spaced, braced and angled for point sourced direction without damaging the beautiful cabinet. Just one small concern/problem on the 700's. Do you have a recommendation on the supplied spikes. They are way to sloppy for good floor coupling the way that they slide into the rubber foot. Is there an alternate solution that I can go with? Maybe a longer spike to replace the supplied "L" foot and rubber foot pad all together. Once again... Thanks for the ride. I am revisiting my whole music library and I can enjoy that lower mid bass in the music. Respectfully, Kevin Franklin

Warranty
I had a Dynamo 700 that went bad after a couple of months and I want to let you know that Martin Logan stands behind its product. I contacted ML and without hesitation they gave me several options on how I wanted to take care of the replacement. I decided to send them the sub directly, I had a new Sub within a few days and was back listening to great music and watching movies with a powerful thump! Thanks ML for your professional service and courtesy.

I am very impressed with this sub. I replaced a 12in sub with the Dynamo 700. I was amazed how much more this sub out preforms the old one.
