Martin Logan - Subwoofer Setup and Optimization

Step Up to Low Frequency Accuracy, Power, and Deeper Bass!

Building on the success of the original Dynamo, our designers went on to create the compact, powerful Dynamo 700. Featuring a high-current 300-watt RMS, 600-watt peak amplifier and 10-inch cone driver, the Dynamo 700 delivers deep, tight, effortless bass for home theater or stereo music. Its standard down-firing configuration quickly (and easily!) converts into a front-firing setup for those who prefer a "hidden" installation. Finishing touch - a wireless receiver for bass aficionados who prefer a clean, minimalist look in the room, no cables in sight.


  • 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 700 incorporates a wireless receiver (digital RF transmission) for use with the optional SWT-1 MartinLogan Subwoofer Wireless Transmitter (sold separately, see dealer) in which case, cable clutter also becomes a moot point!
  • High-Resolution Low-Distortion 10-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 Advanced Thin-Film (ATF) driver technologies.
  • Advanced Ultra-Efficient 300-Watt Amplifier - The Dynamo 700'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 700's amp consumes less than a single watt in Standby mode.
  • 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.
  • Front-Firing or Down-Firing Configuration - To maximize performance when installed inside of a cabinet or other discrete installation, the Dynamo 700'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.
  • Seamless System Integration: Engineered for Stereo and Home Theater - Comprehensive connection options, low-pass filtering and phase control make integrating the Dynamo 700 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 700 offers an LFE input that bypasses its internal filters.
  • Sealed System - 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 music or movie source material. Listen carefully to the sound of a bass drum and you'll hear the difference. The Dynamo 700's cabinet is constructed from the finest composite material for acoustic integrity.
  • Energy Transfer Coupler (ETC) Spikes - The Dynamo 700 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.
