Dynamo Series Powered Subwoofer: The MartinLogan Dynamo 1000w
powered subwoofer offers audiophile grade performance and home-friendly
aesthetics. Featuring a high-current 500-watt RMS (1,000-watt peak) amplifier and
a 12" cone driver, the Dynamo 1000w delivers deep, tight, effortless bass for
movie and music soundtracks. It can be configured as a down-firing or
front-firing powered sub. The 1000w offers both a wired and wireless powered
subwoofer connection to your home AV entertainment system.
Advanced, Ultra-Efficient 500-Watt Amp: The Dynamo 1000w'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 500-watts of continuous power (1,000-watts peak).
High-Resolution, Low-Distortion 12" Woofer: The Dynamo
1000w's advanced-technology driver pairs a high-power magnet structure with a 12"
polypropylene 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
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 1000w'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 1000w maintains a smooth, consistent response regardless of music or movie
Front-Firing or Down-Firing Configuration: To maximize
performance when installed inside of a cabinet or other discrete installation,
the Dynamo 1000w'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:
- Down-Firing Orientation (default): 13.75" (w) x 14.5625" (h) x 15.0625" (d)
- Front-Firing Orientation: 13.75" (w) x 15.5" (h) x
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 1000w
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 1000w offers an LFE
input that bypasses its internal filters. The phase control can be set to 0, 90,
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 1000w 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
Energy Transfer Coupler (ETC) Spikes: The Dynamo 1000w 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 1000w 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
