In this article, Zami Schwartzman shares his personal journey to design and perfect his own accelerometer-based motion feedback desktop subwoofers, including plate amplifiers with MFB control, crossover and voice coil thermal protection that can be matched with any low frequency MFB driver. The proof of concept demonstrated the ability to perfectly complement popular active nearfield monitors, mitigating the effects of room reflection.
