Dynamo 400

Product Highlights

  • 8-inch
    inverted surround poly cone woofer
  • 150
    Watts (peak) amplifier
  • Low-turbulance,
    ported design
  • RCA and
    speaker level inputs

 

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.

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.

LOW-TURBULANCE PORTS

When properly optimized and executed, ports are
a convenient, cost- effective way to increase low-frequency output. Dynamo 400
and 600X feature tuned, long low-turbulence ports designed to provide superb
low-end extension while minimizing port induced distortion.
