MARTINLOGAN SUB
CONTROL APP

(AVAILABLE FOR iOS AND ANDROID)

MartinLogan’s Subwoofer Control app uses a Bluetooth
connection to simplify setup and configuration of Dynamo 600X, 800X, 1100X, and
1600X. 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. 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.

ARC MOBILE APP

(AVAILABLE FOR iOS AND ANDROID)

In the lab, MartinLogan engineers strive for transparency.
Outside the lab, there’s one wildcard our engineers can never account for—the
listening room. The unique size and shape of a listening space (and its
contents) can make bass waves do unpredictable things, greatly affecting a
subwoofer’s overall performance. Anthem Room Correction measures low-frequency
sound output in a room and 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— realistically
blended, natural-sounding bass. Dynamo 600X, 800X, 1100X, and 1600X utilize a
Bluetooth connection with a smartphone or USB connection with a PC to run
Anthem Room Correction.

UNIQUE FRONT-FIRING
OR DOWN-FIRING DESIGN

When placed in a cabinet or other discreet location, Dynamo
800X, 1100X, and 1600X subwoofers can easily convert from standard down-firing
to front-firing orientation, with no tools or special skills required. A grille
is provided for use in front-firing applications.

OPTIONAL SWT-X WIRELESS INPUT (sold separately)

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, Dynamo 600X, 800X, 1100X, and 1600X include a connection
port for an optional wireless system. MartinLogan’s new SWT-X Wireless
Subwoofer System (sold separately) incorporates the latest in wireless audio
transmission technology, including 2.4GHz dynamic frequency selection, forward
error correction, and a range up to 50 feet. Easy to install in the subwoofer,
the SWT-X receiver requires no external power source or audio connections.

LEFT AND RIGHT
2-CHANNEL INPUTS

Dynamo 400, 600X, 800X, 1100X, and 1600X subwoofers feature
left and right input via RCA line level as well as speaker level connections.
LFE HOME THEATER INPUT
Dynamo 400 and 600X’s right inputs double as an LFE
input for home theater applications. Dynamo 800X ups the ante by adding a
discrete LFE RCA line level input. Dynamo 1100X and 1600X go one step further
by adding both XLR and RCA inputs for LFE connection.

12V TRIGGER INPUT

Dynamo 800X, 1100X, and 1600X feature 12V Trigger Inputs,
allowing an external device to turn the subwoofer on and off.

SIMULTANEOUS LFE AND
2-CHANNEL CONNECTIONS

Dynamo 800X, 1100X, and 1600X subwoofers features left and
right input via robust connection and a control system that allows simultaneous
connection of both 2-channel stereo music and multi-channel home theater and
allows each source to have individual crossover and level settings, giving
listeners a perfect performance in every application. LFE inputs use no
low-pass filter, leaving crossover control to the processor. Left and right
inputs integrate discrete user-adjustable low-pass filters allowing different
level and crossover points when playing back two channel music.

POWERFUL,
HIGH-EXCURSION, LOW-TURBULENCE, INVERTED SURROUND WOOFERS

The latest generation of MartinLogan Dynamo subwoofers
feature advanced-design woofers with inverted surrounds and powerful magnet,
motor, and suspension designs. In front-fire mode the unique inverted surround
design maximizes excursion clearance behind the grill cover. When positioned in
a down-firing configuration, the inverted surround significantly reduces
airflow related turbulence for an articulate and detailed low-frequency
experience. These advanced-technology woofers pair a high-power magnet
structure (significantly more robust than previous generations) with low-mass
diaphragms to provide massive excursions 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 subwoofers has been
meticulously designed to deliver a staggering low-frequency performance – all
without a hint of distortion.

ADVANCED
ULTRA-EFFICIENT SWITCH MODE POWER SUPPLIES AND CLASS-D AMPLIFIERS

Dynamo subwoofer class-D amplifiers operate with extremely
low levels of distortion and deliver 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.

INVERSE MATHEMATICAL
EQUALIZATION (IME) FILTER

The IME filter used in the Dynamo 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.

SEALED CABINET WITH
EXTENSIVE INTERNAL BRACING

Although ports, when correctly designed, are a convenient
and cost-effective way of increasing low-frequency output, when used in small
cabinets their reliance on resonant energy can impair bass quality. Dynamo
800X, 1100X, and 1600X are compact, sealed subwoofer systems that minimize
transient-blurring group delay while maintaining smooth, consistent response,
regardless of music or movie source material. The cabinets are 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 levels.

BUILT-IN ETC^™ (ENERGY
TRANSFER COUPLER) SPIKES

Dynamo 800X, 1100X, and 1600X come with
custom ETC spikes which can be used to enhance stability on thick carpets, or
create tighter coupling between subwoofer and floor to enhance overall sound
quality. The built-in spikes are conveniently and discretely hidden underneath
the rubber feet.
