The high-gloss black Dynamo 1500X 15” Subwoofer from MartinLogan features a 650W (1300W peak) amplifier and a 15” low distortion woofer with a powerful magnet structure to deliver huge excursion and output while preserving subtle bass detail. It features XLR, RCA, and 12V trigger inputs for connection flexibility while simplifying system integration. With the separately available PBK (Perfect Bass Kit) room correction system, you can tailor the subwoofer's performance to the acoustic properties of your listening environment, using your computer and a microphone.
Powerful, High-Excursion 15" Woofer
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 damping properties ensure a smooth, non-resonant response.
Front-Firing and Down-Firing Design
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 skills required.
Advanced Ultra-Efficient Amplifier Design and Inverse Mathematical Equalization (IME) Filter
An IME filter is derived from the inverse of the unfiltered driver response. Precision IME filtering yields extremely accurate low-frequency response. The Dynamo 1500X delivers a true 650W of continuous power and 1300W peak. An energy-conscious design, the Dynamo Series amps consume only 10W in standby mode.
Sealed Cabinet with Internal Bracing
A compact, sealed subwoofer system minimizes transient-blurring group delay while maintaining smooth, consistent response, regardless of music or movie source material. Inside, critically placed structural cross-bracing acts as a baffle for the woofer, while the added rigidity keeps cabinet-induced resonances and non-linearities to inaudible levels.
Seamless System Integration
Comprehensive signal connections along with low-pass filtering and phase control make the integration of Dynamo 1500X subwoofer 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.
ETC (Energy Transfer Coupler) Spikes
The Dynamo 1500X comes with custom ETC spikes that 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.
Perfect Bass Kit (PBK) Ready
The Dynamo 1500X features PBK room correction, it uses a computer and microphone to listen throughout the listening environment and tailor the woofer's performance to the acoustic properties of a room-resulting in clean, powerful bass down to 20 Hz.
