Ever have trouble finding the perfect spot for your sub? Well, with MartinLogan's Dynamo 700W subwoofer, you'll have lots of options. This versatile sub's standard down-firing setup is perfect for placing it in corners or along side walls. But if you're looking for a more discreet placement such as in a cabinet with your other home theater gear, you can easily convert it into a front-firing sub by simply removing and reorienting its detachable feet.
Even if you're willing to place your sub far from your receiver, you might not want a long wire running between the two. No worries, thanks to the 700W's built-in wireless receiver and included transmitter. So you can feel those deep rumbling movie sound effects without tripping over a cable when you get up to get more popcorn.
When you add a subwoofer to your full-range speaker system, your movies and music will sound fuller and more dramatic. The Dynamo 700W accomplishes this without taking up valuable real estate in your living room or home theater. The sealed enclosure is constructed of high-density materials and reinforced with solid internal bracing to minimize cabinet resonance for cleaner sound. The 10-inch speaker is driven by a high-powered built-in amplifier that delivers 300 watts of continuous, clean power. Both are optimized for low noise and distortion, to produce bass that is not only bold, but detailed and tight rather than loose and boomy. That makes this sub a great performer with movies and music — not to mention a great match with MartinLogan's fine lineup of full-range speakers.
The Dynamo 700W's detachable feet let you easily orient the woofer in a down- or front-firing configuration.
A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.
For being a small subwoofer it sure packs a punch . It brought out the lows that I was missing .great addition to my Martin Logan set up.
Pros: It's wireless . I like the small size does not take up to much space.
I'm still amazed at the sound and power of this subwoofer, from a cube that's about 12x12x12 inches. It can literally rattle the walls (which I did accidentally when first setting up). I've had 2 other subs ( Sony and John Thomas) that couldn't hold a candle to this MartinLogan. It took a little playing around to find the optimal location (thank goodness it's wireless except for the power cord), but I found the sweet spot, so the bass seems to come from the PSB X2Ts I also purchased from Crutchfield. I listen almost exclusively to classical music (specifically baroque), and although the PSB X2Ts have dual 6 1/2 inch woofers, this sub adds a true extra dimension. I highly recommend it.
Pros: Quality of construction and (needless to say) sound that you hear and feel, without making your ears bleed.
Cons: None. I do agree with another review that a piece of electrical tape over the lights would be beneficial (they could serve as night lights).
Great sound, exceptionally powerful, fantastic companion to Vision soundbar.
Pros: Great sound, awesomely powerful
Cons: Subwoofer shuts itself off when watching tv shows or video at lower volumes. Have to turn volume up on soundbar to turn sub back off. Controls don't make it easy to fine tune settings.
Wireless was a plus especially for the wife who hated wires around. Have heard bass that I had not with a Bose Acoustimass 15. Blended seamlessly with my Martin Logan LX-16 and Motion 8 Center Channel.
Pros: Ease of use and great sound.
Wireless feature is outstanding for difficult placement situations..Set up is effortless and they blend in perfectly with two Definitive Technology Studio Monitor 55's in a 12 by 20 ft room with large openings at either end.A larger sub would be superfluous.
Pros: versatile and great value for the money
Awesome, I already had a sub and wanted to add a second. I'm using this one in wireless mode, no interference so far. The sound is great, still tweaking the placement and gain. I have it firing downward. Thinking about placing tape over blue light in back. Already I can tell it's the best sub in the house. The only problem was the first sub I got a random thumping noise, I advised Crutchfield and they immediately sent out another. This one worked perfectly. No regrets
Pros: Great addition, I want to say it added warmth to the music. I'm playing a lot of old school R & B, the bass is tight.
Cons: Non, so far
This is a very solid and powerful sub. I have it connected through my Martin Logan Motion View sound bar, and the sub delivers quite a punch when it's active. The key word there is active. If the volume on the sound bar is low or you're watching a sitcom or scene with not a lot of bass, the sub does go into stand by mode. And in order to get it active again, you have to turn the sound up in order for it to register. I have not determined whether this is attributed to the sub being connected through a wireless connection versus a direct connection into the sub. Also, there are times the sub doesn't register a signal during a non HD movie (meaning no surround sound). I would think the sub would still come on, but it does not.
Pros: Powerful sound when hooked up Easy to connect via a wireless connection Configuration options to make it fire down or out
Cons: Inconsistently goes in and out of stand by mode During scenes with heavy dialog and no background music or sound, the sub sometimes transmits a tick / popping sound. Don't know if that is because of wireless interference or something else
Great Product and Great Service.
Pros: Great sound, easy to set up.
Sounds as good as it looks. Located sub about 20ft. away from Yamaha receiver (which is located in an armoire) with no pick-up or distortion issues. If you want a wireless sub you certainly can't go wrong with this one.
Pros: Quality. Ease of installation. No wires !!!!
Big sound. Wifi great. does make a cycling noise when going into energy saver mode that is disconcerting

Dynamo Series Powered Subwoofer: The MartinLogan Dynamo 700w powered subwoofer offers audiophile grade performance and home-friendly aesthetics. Featuring a high-current 300-watt RMS (600-watt peak) amplifier and a 10" cone driver, the Dynamo 700w delivers deep, tight, effortless bass for movie and music soundtracks. It can be configured as a down-firing or front-firing powered sub. The 700w offers both a wired and wireless powered subwoofer connection to your home AV entertainment system.
Advanced, Ultra-Efficient 300-Watt Amp: 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 (600-watts peak).
High-Resolution, Low-Distortion 10" Woofer: The Dynamo 700w's advanced-technology driver pairs a high-power magnet structure with a 10" poly 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 poly cone material also ensure the smooth, non-resonant response necessary for truly seamless blending with MartinLogan's electrostatic panel and Folded Motion driver technologies found in their loudspeakers.
Inverse Mathematical Equalization (IME) Filtering: 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 w/ Internal Bracing: 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. As a result the MartinLogan Dynamo 700w maintains a smooth, consistent response regardless of music or movie source material.
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 grille cover and 90-degree RCA adaptors are provided for use in front-firing applications. Dimensions:
Note: If placing the powered subwoofer inside of a cabinet, it is recommended that there be a minimum of 3" of open space between the cabinet and the front and back sides of the powered sub.
Seamless System Integration: 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 the AV receiver supplies the low-pass crossover, the Dynamo 700w offers an LFE input that bypasses its internal filters. The phase control can be set to 0, 90, or 180-degrees.
Built-in Wireless Receiver: Although correct placement plays a key role in optimizing subwoofer performance, sometimes it imposes the inconvenience 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 which plugs into the subwoofer or LFE output of your home receiver or active soundbar speaker via stereo RCA (cable not included).
Energy Transfer Coupler (ETC) Spikes: The Dynamo 700w comes with custom ETC spikes which can be used along with the pre-installed rubber feet to enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality. The spiked feet add 0.625" of height to the powered sub.
Auto Power On/Off: The powered subwoofer will automatically enter a power saving mode when no audio signal is detected. The subwoofer will automatically come out of power saving mode when an audio signal is detected.
Break-In Period: The Dynamo 700w woofer requires approximately 50 hours of break-in at moderate listening levels before its optimal performance occurs. This will factor in on any critical listening and judgment.
Looked like what I needed [ Steven Jan 01, 2016 ]
Great sounds [ CINDI Dec 13, 2015 ]
I'm not really sure how to answer this except to say that mine is matched up to a McIntosh MA 5200 and it works just fine, but the room is rather small (14x14 w 10' ceiling) so I don't crank the sub up but a little. [ Steven Nov 20, 2015 ]
Yo don't. It has a built in amp. You size the sub to the room. [ JEFFREY Nov 20, 2015 ]
Unfortunately I cannot be of assistance. I purchased my speakers for a move and they are still in the factory packaging. Sorry [ MICHAEL H Nov 20, 2015 ]
The sub is self powered. You just need to connect to your sub pre amp out or LFE. Also this sub is wireless. [ CALVIN L. Nov 20, 2015 ]
Since the Dynamo is a powered subwoofer it should not draw off the receiver. I have a 8 year old H/K receiver with 75 watts per channel. I played the Saint-Saens Organ Symphony and there was absolutely no problem. The wood floor literally shook due to the down firing bass driver. It is also great due it is wireless capability with no wires running from the unit, [ Gordon F. Nov 20, 2015 ]
You can get any receiver. It has gain so you can shape the sound to come in soft for low power or hard for big power. [ BRYAN Nov 20, 2015 ]
