Step Up to Accurate Low Frequency Power
Building on the success of the original Dynamo powered subwoofer, MartinLogan's designers went on to create the compact, powerful Dynamo 700.
Featuring a high-current 300-watt RMS, 600-watt peak amplifier and 10" cone driver, the Dynamo 700 delivers deep, tight, effortless bass for home theater or stereo music. Its standard down-firing configuration quickly converts into a front-firing setup for folks who prefer a "hidden" installation.
The finishing touch is Dynamo's built in wireless receiver wireless receiver, which works with the included SWT-1 wireless transmitter for cable-free hook-up. This great features is just the ticket for bass aficionados who want an uncluttered, minimalist look in the room.
"Forceful and Clean"
"Not only did the Dynamo 700 give me true full-range sound, it had a pinpoint curative effect on the response curves of the partnered speakers," notes Ron Doering in his December 15, 2010 review for SoundstageNetwork.com.
"What did stand out for me was how forceful and clean, but not exaggerated, the bass response was even at low volume levels," reports Robert Silva at HomeTheaterAbout.com. "The Dynamo 700w exhibited very little, if any, unnatural low frequency drop off at any volume level, and had excellent recovery time between dynamic bass peaks."
Affordable Low-Bass Muscle
MartinLogan never lets up! Thanks to the high-end loudspeaker manufacturer's ceaseless research into driver, amplifier, cabinet, and control technologies, it has developed a highly affordable solution for enthusiasts of deep bass. The new family of Dynamo powered subwoofers delivers the low frequency muscle that today's movies and music requires, with an emphasis on highly accurate reproduction.
Front-Firing or Down-Firing Flexibility
Dynamo is user-configurable for either front- or down-firing operation. Just pick up the sub, flip it over 90 degrees on the included stand, and you've changed front front-firing to down-firing, or vice versa. Whether in a corner, behind furniture, or installed in a cabinet, your Dynamo will sound superb.
Inverse Mathematical Equalization
An IME (inverse mathematical equalization) 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 typical of competitively priced subwoofers.
Seamless System Integration
Dynamo's connections and controls are designed to enable easy, seamless integration with any stereo music or multi-channel home theater system. It's main left/right line-level inputs feed into a precision low-pass filter. For systems in which a surround processor supplies the crossover, Dynamo provides an LFE input that completely bypasses its internal filters.
This capability together with flexible crossover controls ensures that Dynamo can deliver excellent bass from any location in your room. No other subwoofer in its class offers Dynamo's combination of bass extension, power, and detail.
Go Wireless with Your MartinLogan Sub
Although correct room placement plays a key role in optimizing subwoofer performance, it can impose the inconvenience (not to mention unsightliness!) of running long lengths of cable through walls, along baseboards or under floors and carpets.
The MartinLogan SWT-1 Subwoofer Wireless Transmitter solves the problem. It allows you to place your Dynamo 700 or Dynamo 1000 subwoofers subwoofer in the exact location where it will deliver the best bass. Cable clutter becomes a thing of the past and actual system setup time can be dramatically reduced. Need to system troubleshoot at a later time? When you go wireless, there will never be an untidy mess of wires to sift through in order to find the right cable.
Solving the Placement Puzzle
While it's true that bass waves are non-directional and, in theory, you should be able to place your subwoofer anywhere in the room without affecting bass performance or the performance of your other speakers, it's never quite that simple. Bass is dramatically affected by the room itself. Dimensions, dead spots, archways, even furniture placement can cause bass to sound bloated or boomy with a lack of definition.
Achieving optimal bass almost always requires experimenting, with the sub in various parts of the room. Ah and there's the rub! While experimenting, you may discover the best place for the subwoofer is all the way across the room, far from the amplifier or receiver. Or maybe a "hidden" install is required. Both situations impose the inconvenience (not to mention unsightliness!) of running a long length of cable through walls, along baseboards or under floors and carpets. That's where the MartinLogan SWT-1 Subwoofer Wireless Transmitter comes in.
MartinLogan Dynamo 700 and Dynamo 1000 subwoofers are designed for wired or wireless operation. A wireless receiver built into each of these subs can be used to establish connection with the SWT-1. The SWT-1 allows you to experiment with subwoofer placement to your heart's content. Unsightly wiring becomes a thing of the past and the actual reduction in system set-up time can be dramatic.
The SWT-1 couldn't be easier to use. Just plug it into the wall, and connect your audio to the left and right / LFE RCA inputs. Press the sync button on the bottom of the transmitter, and you're done. You're ready for stunning bass performance, wirelessly.
Skeptical About Wireless Audio? Relax!
Skeptical about wireless audio? You can relax! Following extensive research and testing, MartinLogan engineers designed the SWT-1 with an uncompressed 16-bit, 48 kHz sampling rate (exceeding the current CD standard of 16-bit, 44.1 kHz), which proved more than adequate (and accurate) for use in the wireless transmission of low-frequency information below 200 Hz. And since the RF transmission is digital, it is error-checked to ensure no deviation from the original signal.
The MartinLogan SWT-1 operates in the 2.4 GHz frequency range. Often, users of wireless technology complain about interference from other noise sources in the room (such as wireless local area networks, portable phones on the same frequency, even microwave ovens). MartinLogan engineers included an integrated RF power amplifier that provides a 15 dBm RF power level to reduce interference. Stray RF interference is also reduced through our use of Adaptive FHSS operation. Think Bluetooth technology; it's similar.
In a typical room situation, the SWT-1's RF transmitter has a maximum unobstructed operating range of 40 feet (12.5 meters) depending on placement of course, and if desired, its compact dimensions allow it to fit neatly into an A/V rack.
MiniETC™ (Energy Transfer Coupler) Spikes
The Dynamo is supplied with sturdy, 1/4-20 MiniETC™ spikes, which can be used in place of the standard feet to enhance stability on thick carpets or to create tighter coupling between speaker and floor.
Although ports are a convenient and cost-effective way of increasing low-frequency output, they rely on resonant energy in a way that impairs bass quality. A good sealed system will exhibit less transient-blurring group delay while maintaining smooth, consistent response regardless of output level or voice-coil temperature. Listen carefully to the sound of a bass drum, and you'll hear the difference.
