Because bass requires sufficient acoustic volume, currently available small speaker systems struggle to provide adequate low frequency content in a small enclosure. The goal of this project was to create a small speaker system with two passive radiators but in a more efficient implementation. One of the passive radiators would use the speaker as the mass for the passive radiator, saving space. Package volume is compressed by locating the rear passive radiator adjacent to the front passive radiator, resulting in an ultra-thin package. The rear passive radiator is also lightly loaded, but force-balanced through area matching to the front passive radiator. An analysis of the design and its efficiency; along with 3D fabrication details and operational performance are discussed in this report.
