Martin Logan Dynamo 700 Black Subwoofer - DYN700WD (Sold As Each)
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 included SWT-1 MartinLogan Subwoofer Wireless
Transmitter (included) 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
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
