MartinLogan Offers New 15-Inch Dynamo Subwoofer

New subwoofer features a powerful amplifier, a 15-inch woofer, font and down-firing configurability and optional room correction.



Indianapolis, IN – CEDIA 2012 – September 5-8 – Sound Room #9 – MartinLogan, the world’s leader in electrostatic and Folded Motion™ loudspeaker technology, proudly announces a powerful new subwoofer. The Dynamo 1500X, MartinLogan’s first to feature room correction, includes a host of new internal and aesthetic design elements and a powerful 650 watt (1300 watt peak) amplifier.

Although correct placement plays a key role in optimizing subwoofer performance, positioning a subwoofer often requires compromises. Dynamo 1500X is MartinLogan’s first subwoofer to feature room correction. The optional MartinLogan Perfect Bass Kit (PBK, sold separately) 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 20Hz.

The new subwoofer features advanced MartinLogan design concepts. A high-resolution, low-distortion woofer pairs a high-power magnet structure with a 15-inch diaphragm to deliver 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.

Setup flexibility is maximized by the subwoofer 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.

For customers seeking relief from the inconvenience (not to mention the unsightliness) of running long lengths of cable through walls, along baseboards or under floors and carpets, the Dynamo 1500X is fully compatible with MartinLogan’s new SWT-2 transmitter/receiver system (sold separately). SWT-2 technology, already found in MartinLogan’s Dynamo 700W and 1000W subwoofers and the Motion Vision soundbar, uses digital radio frequency (RF) transmission to wirelessly send CD-quality audio to the subwoofer.

Advanced Ultra-Efficient Amplifier Design

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.

Seamless System Integration

Comprehensive signal connections and 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 bypasses internal filters. Additionally, a trigger input allows processors to turn the Dynamo 1500X on and off via a 12V trigger connection.

Sealed System

Although ports are a convenient and cost-effective way of increasing low-frequency output, their reliance on resonant energy impairs bass quality. A good sealed system exhibits less transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material.

Sealed Cabinet with Extensive Internal Bracing

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.

Finish Options & Availability

MartinLogan Dynamo 1500X will be shipping in December 2012 and be available in Satin Black ($1,595 US MSRP) and High-Gloss Piano Black ($1,895 US MSRP). PBK room correction sold separately ($99 US MSRP).
