MartinLogan Dynamo 1500X 15″ Powered Subwoofer

Description

MartinLogan’s New Flagship Powered Sub for Mega Bass
Excitement

Want mega bass power for infusing movies and movie with
maximum low frequency excitement? Of course you do! You want the Dynamo 1500X.
It features advanced MartinLogan engineering including a 650-watt RMS,
1300-watt peak amplifier and a 15″ low distortion woofer.

The Dynamo 1500X’s XLR, RCA, and 12-volt trigger inputs
guarantee connection flexibility while simplifying system integration. Its
standard down-firing configuration quickly and easily converts into a
front-firing setup for those who prefer a ‘hidden’ installation. And with
MartinLogan’s optional PBK room correction (sold separately), the Dynamo 1500X
is guaranteed to sound exceptional in any room.

Powerful, High-Excursion 15″ Woofer

The Dynamo 1500X features advanced MartinLogan design
concepts. A high-resolution, low-distortion 15″ woofer delivers huge
excursion and sound output while preserving minute bass details, all without a
hint of distortion. The cone material’s exceptional damping properties ensure
the smooth, non-resonant response necessary for seamless blending with
MartinLogan electrostatic panel and Folded Motion driver technologies.

Advanced Ultra-Efficient Amplifier Design

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 most subwoofers in this price
range. The Dynamo 1500X delivers a true 650 watts of continuous power and 1300
watts peak. An energy-conscious design, the Dynamo Series amps consume only 10
watts in standby mode.

Unique Front-Firing, Down-Firing Design

Placement flexibility is maximized by the subwoofer’s
front-firing or down-firing options. When placed in a cabinet or other discreet
location, the Dynamo 1500X subwoofer can easily convert from standard
down-firing to front-firing orientation, with no tools or special skills
required. A grill cover and 90-degree RCA adaptors are provided for use in
front-firing applications. Further flexibility is afforded by custom energy
transfer coupler (ETC™) spikes, which can enhance stability on thick carpets,
or create tighter coupling between subwoofer and floor to enhance overall sound
quality.

Perfect Bass Kit (PBK) Ready

Although correct placement plays a key role in optimizing
subwoofer performance, positioning a subwoofer often requires compromises. Not
anymore, thanks to MartinLogan’s Perfect Bass Kit (PBK, sold separately). The
Dynamo 1500X is MartinLogan’s first subwoofer to feature PBK room correction.
PBK uses a computer and microphone to listen throughout the listening
environment and tailor the sub’s performance to the unique acoustic properties
of a room – resulting in clean, powerful bass down to 20 Hz.

Sealed Cabinet with Extensive Internal Bracing

Although ports are a convenient and cost-effective way of
increasing low-frequency output, when used in small cabinets their reliance on
resonant energy impairs bass quality. A compact, sealed subwoofer system
minimizes transient-blurring group delay while maintaining smooth, consistent
response, regardless of music or movie source material. The Dynamo 1500X’s
cabinet is constructed from the finest composite material for acoustic
integrity. Inside, critically placed structural cross-bracing acts as an
excellent baffle for the woofer, while the added rigidity keeps cabinet-induced
resonances and non-linearities to inaudible levels.

Engineered for Stereo and Home Theater

Comprehensive signal connections along with low-pass
filtering and phase control make the integration of Dynamo 1500X subwoofers
into a multi-channel home theater or stereo music setup a simple and seamless
process. The main left/right line-level inputs feed into a precision low-pass
filter with a cut-off frequency variable from 35 to 150 Hz. For systems in
which a surround processor supplies the crossover, the Dynamo Series offers a
LFE input, via either XLR or RCA connections, which bypass internal filters.
Additionally, a trigger input allows processors to turn the Dynamo 1500X on and
off via a 12V trigger connection.

Energy Transfer Coupler (ETC) Spikes

The Dynamo 1500X 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 sound quality.

The Dynamo 1500X subwoofer system consists of a single woofer
for high SPL output with minimal distortion. The equalization used is
specifically designed to counteract the response of the woofers sealed box
response. This equalization leads to minimal group delay and proper transient
response.
