MARTINLOGAN INTRODUCES THE DYNAMO SERIES: SUBWOOFERS WITH WIRELESS CAPABILITIES AND MUSCLE
 
The Dynamo 700 and Dynamo 1000 feature proprietary technology and design elements with optional wire-free performance.
 
Atlanta, GA – CEDIA EXPO 2009 – September 10 – 13, 2009 – Hall C Booth SR-10 – MartinLogan, the Great American Speaker Company, is proud to announce the Dynamo 700 and Dynamo 1000 subwoofers. The Dynamo Series models, MartinLogan’s first to feature built-in wireless receivers, include a host of new internal and aesthetic design elements.
 
Although correct placement plays a key role in optimizing subwoofer performance, it often imposes the inconvenience (not to mention the unsightliness) of running long lengths of cable through walls, along baseboards or under floors and carpets. The Dynamo Series solves this problem by incorporating a wireless receiver using digital radio frequency (RF) transmission for use with the optional SWT-1 MartinLogan Subwoofer Wireless Transmitter (sold separately).
 
The new subwoofers feature advanced MartinLogan design concepts exclusive to the Dynamo 700 and 1000. A high-resolution, low-distortion woofer pairs a high-power magnet structure with the diaphragm (12-inch for the 1000, 10-inch for the 700) to deliver huge excursion and sound output while preserving minute bass details, all without a hint of distortion. The cone material’s exceptional damping properties ensure the smooth, non-resonant response necessary for seamless blending with MartinLogan electrostatic panel and Advanced Thin Film (ATF) driver technologies.
 
Setup flexibility is maximized by the Dynamo Series’ front-firing or down-firing options. When placed in a cabinet or other discreet location, each Dynamo Series subwoofer can easily convert from standard down-firing to front-firing orientation, with no tools or special skills required. A grill cover and 90-degree RCA adaptors are provided for use in front-firing applications. Further flexibility is afforded by custom energy transfer coupler (ETC) spikes, which can enhance stability on thick carpets, or create tighter coupling between subwoofer and floor to enhance overall sound quality.
 
 
 
Pricing:
MartinLogan Dynamo 700 - $695 each U.S. Retail
MartinLogan Dynamo 1000 - $995 each U.S. Retail
 
 
Additional MartinLogan Dynamo Series Features:
 
Advanced Ultra-Efficient Amplifier Design
The Dynamo Series’ 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. The Dynamo 1000 delivers a true 500 watts of continuous power; the Dynamo 700 provides a true 300 watts of continuous power. An energy-conscious design, the Dynamo Series amps consume 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 that is far superior to that provided by the simple second-order high-Q filters typically found in subwoofers in this price range.
 
Seamless System Integration
Comprehensive signal connections and low-pass filtering and phase control make the integration of Dynamo Series subwoofers into a multi-channel home theater or stereo music setup a simple and seamless process. 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 Series 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, their reliance on resonant energy impairs bass quality. A good sealed system exhibits less transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material.
 
Sealed Cabinet with Extensive Internal Bracing (Dynamo 1000 only)
The Dynamo 1000’s cabinet is constructed from the finest composite material for acoustic integrity. Inside, critically placed structural cross-bracing acts as an excellent baffle for the woofer, while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.
 
Dynamo subwoofers will ship this month. For more information, please visit www.MartinLogan.com.
