This is my implementation of a loudspeaker with the unique and famous Manger MSW driver. Unlike with conventional loudspeaker drivers with rigid membranes, the Manger MSW is a bending-wave driver. The movement of the voice coil at the center of the highly flexible membrane induces a wave that travels radially towards the edge of the membrane. This is similar to the surface waves that result from throwing a stone into a pond. The Manger MSW has a flat frequency response from 300 Hz and higher, so it’s highly suitable for a very high-quality FAST (full range and subwoofer technology) loudspeaker system. I designed this small floor-standing loudspeaker around a Manger MSW WO-5 and a Visaton TIW 200 XS woofer mounted on the side of the enclosure. Both the MSW and the woofer are driven by a dedicated power amplifier using DSP filters. The crossover-frequency between the MSW and the woofer is about 300 Hz. Detailed notes and measurements taken during the development of the Mangerbox are available in a separate PDF document.
