The MartinLogan Dynamo Foundation 12 is engineered to bring powerful, accurate bass to high-performance home audio and home theater systems. Combining advanced acoustic engineering with a compact, elegant design, it delivers impressive low-frequency extension while maintaining precise and controlled sound reproduction.
At its core is a custom-designed 12-inch high-excursion Ultra-Rigid Polypropylene (URP) woofer housed in a stamped steel basket. Its rigid cone construction provides excellent strength and minimizes unwanted distortion, allowing the subwoofer to reproduce deep bass with remarkable accuracy and impact.
Powering the driver is MartinLogan's Magnitude MT-700 Class D amplifier, delivering 350W of continuous power and up to 700W peak output. The amplifier works alongside a high-resolution 200MHz DSP engine with 56-bit processing, optimizing performance and ensuring accurate, low-distortion bass reproduction.
The sealed MDF enclosure features a reinforced woofer baffle designed to minimize unwanted cabinet resonance and improve overall acoustic performance. Its down-firing driver configuration provides a clean, grille-less appearance that integrates easily into different room environments.
For flexible system integration, the Dynamo Foundation 12 includes stereo RCA and LFE inputs, making it compatible with a wide range of AV receivers, processors, and stereo amplifiers. It also supports the optional WSK-1 Wireless Subwoofer Kit for convenient wireless connectivity.
With a frequency response extending down to 24 Hz, the Dynamo Foundation 12 delivers powerful, detailed bass for movies, music, and immersive home entertainment systems.
