Powerful, High-Excursion Woofer: The MartinLogan Dynamo 1100X powered
subwoofer features and advanced-design 12" polypropylene cone woofer with an inverted
rubber surround and stamped steel basket, along with a powerful magnet, motor, and suspension design. This advanced-technology woofer
pairs a high-power magnet structure with a low-mass diaphragm to provide massive
excursion while perfectly preserving the tiniest bass detail. The exceptional
damping properties of the cone ensure a smooth, non-resonant response necessary
for truly seamless blending with high-performance loudspeakers. Every element of
Dynamo 1100X powered subwoofer has been meticulously designed to deliver an
outstanding low-frequency performance without a hint of distortion.
Class D Amplifier Technology: The Dynamo 1100X powered subwoofer's
class-D amplifier is rated at 650 watts (RMS)/1300 watts (Peak), operates with extremely low levels of distortion, and delivers
dynamic impact with plenty of overhead. Low- noise, high-power switching power
supplies produce clean power efficiently in a small space and effortlessly
provide tremendous levels of current. Both feature high-quality MOSFET
transistors, transformers, noise-suppression networks, and control circuitry.
The switching power supply combined with reliable class-D technology means
there's virtually no energy lost in the subwoofer system.
Acoustically Inert Sealed Enclosure: The Dynamo 1100X features a
compact, sealed (acoustic suspension) enclosure that minimizes
transient-blurring group delay while maintaining smooth, consistent response,
regardless of music or movie source material. The cabinet is constructed from
the finest composite material for acoustic integrity. Inside, critically placed
structural cross-bracing provides a stable foundation for the woofer, while the
added rigidity keeps cabinet-induced resonances and non-linearities to inaudible
Inverse Mathematical Equalization (IME) Filter: The IME filter used in
the Dynamo series powered subwoofers is derived from the inverse of the
unfiltered driver response. Precision IME filtering yields extremely accurate
low-frequency response; superior to that provided by the simple second-order
high-Q filters typically found in subwoofers in this price range.
Volume Level Control: The volume level control (min-max) on
the powered subwoofer can be dialed in to match the output level of
your loudspeakers. All other controls (such as the Low Pass Filter,
Phase/Polarity, Listening Modes, and more) are handled through the MartinLogan
Subwoofer Control app for Apple iOS and Android (see below). The volume level
control can also be done from the app (there is a switch on the subwoofer to
between using the volume level dial or the mobile app).
MartinLogan Subwoofer Control App: MartinLogan's Subwoofer Control app
5.0+) uses a Bluetooth connection to simplify setup and configuration of the
Dynamo 1100XX from your compatible smartphone or tablet device. App based
controls include volume level, low-pass filter (frequency and order), phase,
20-30Hz level, three preset listening modes, and control of Anthem Room
Correction. A unique tone sweep feature assists users in locating areas in
listening rooms where troublesome rattles or resonances may occur.
- Volume Control & Tone Sweep: Volume Control allows you to adjust
the loudness of your subwoofer from -40dB to 12dB. A unique Tone Sweep
feature assists users in locating areas in listening rooms where troublesome
rattles or resonances may occur. A single press of a button allows listeners
to initiate a tone sweep from 20-120Hz. If a rattle or resonance occurs in
the room any frequency can be held, allowing the listener to investigate and
identify the source of the unwanted noise
- Low Pass Filter: The Low Pass Filter screen lets you to adjust
the low-pass frequency for the left and right (RCA or speaker level) inputs
and select between a third or fourth order crossover. This setting is not
applied to the LFE input, instead leaving the task of bass management to
your audio/video processor. If you're using this subwoofer as a dedicated
LFE channel, just set the Low Pass Filter to "Bypass".
- Phase/Polarity: The Phase/Polarity screen allows you to adjust
the phase of the subwoofer from 0-180° in increments of 1° and also allows
you to invert the polarity of the phase.
- Listening Modes: Listening Modes let you apply preset listening
modes to the subwoofer output. The Movie listening mode is an aggressive
setting that maximizes device output for an especially explosive experience.
The Music listening mode is balanced for an accurate musical presentation.
The Night listening mode reduces bass output for discrete playback.
- 20-30Hz Level: The 20-30Hz Level control allows you to adjust
subwoofer output from -10dB to +10dB in the 20-30Hz range; a range where
peaks (room gain) and dips of different amplitudes often develop in
listening rooms. This control can also be used to add a little extra bass
boost to your system when you feel the need.
Anthem Room Correction (ARC) Mobile App: The Dynamo 1100X supports the
Anthem Room Correction App (for
Apple iOS 9.2+ and
Android OS 5.0+)
through a Bluetooth connection with your compatible smartphone or tablet device.
The Anthem Room Correction app utilizes the microphone in your compatible mobile
device and measures low-frequency sound output in a room, and then compares it
to optimal response curves that account for spatial anomalies. The advanced
algorithms of Anthem Room Correction effectively remove anomalies, leaving only
the ideal standard with realistically blended, natural-sounding bass.
Line-Level & Speaker-Level Inputs: The MartinLogan
Dynamo 1100X powered subwoofer features left/right stereo inputs via RCA
line-level, a LFE input via RCA and XLR, and speaker-level inputs in the way of banana
- Discrete Stereo & LFE Inputs: The Dynamo 1100X's dedicated stereo
(RCA) and LFE (RCA/XLR) inputs allow simultaneous connection of both two-channel stereo
music and multichannel home theater and allows each source to have
individual crossover and level settings, giving listeners a perfect
performance in every application. The LFE input uses no low-pass filter,
leaving crossover control to your AV receiver. Left and right inputs
integrate discrete user-adjustable low-pass filters allowing different level
and crossover points when playing back two channel music.
- Banana Plug Speaker Terminals: The powered sub's speaker-level inputs consist of banana plugs for
use with single banana connectors only. The speaker level inputs will not support bare
wire connection and do not support dual banana connectors.
Optional Wireless Receiver & Transmitter: The Dynamo 1100X includes
a USB-A connection port for MartinLogan's optional
SWT-X Wireless Receiver & Transmitter (sold separately). The SWT-X Wireless
Receiver Transmitter kit incorporates the latest in wireless audio transmission
technology - including 2.4GHz dynamic frequency selection, forward error
correction, and a range up to 50'. Easy to install, the SWT-X receiver requires
no external power source or audio connections at the powered subwoofer (simply
plug it into the USB-A port on the the 1100X). The SWT-X
transmitter features RCA jacks which will need to be connected to your AV
receiver's subwoofer/LFE output, plus an included external AC power adapter will
need to be plugged into an AC wall outlet.
Mounting Options: The MartinLogan Dynamo 1100X can be configured as a
front or down firing powered subwoofer for different applications. It also comes
with rubber & spike feet for different floor types.
- Front or Down Firing: When placed in a cabinet or other discreet
location, the Dynamo 1100X powered subwoofer can easily convert from a
down-firing to front-firing orientation, with no tools or special skills
required. A grille is provided for use in front-firing applications.
- Rubber & Spike Feet: The Dynamo 1100X comes with custom ETC spikes
which can be used to enhance stability on thick carpets, or create tighter
coupling between the subwoofer and your floor to enhance overall sound
quality. The built-in spikes are conveniently and discretely hidden
underneath the rubber feet.
